This makes it impossible for a malicious sender to try to make + the receiver use an unsafe destination path for a transferred file, such + as a just-sent symlink. + BUG FIXES: - - ... + - Change the checksum seed order in the per-block checksums. This prevents + someone from trying to create checksum blocks that match in sum but not + content. + - Fixed a with the per-dir filter files (using -FF) that could trigger an + assert failure. + - Only skip set_modtime() on a transferred file if the time is exactly + right. + - Don't create an empty backup dir for a transferred file that doesn't + exist yet. + - Fixed a bug where --link-dest and --xattrs could cause rsync to exit if + a filename had a matching dir of the same name in the alt-dest area. + - Allow more than 32 group IDs per user in the daemon's gid=LIST config. + - Fix the logging of %b & %c via --log-file (daemon logging was already + correct, as was --out-format='%b/%c'). + - Fix erroneous acceptance of --info=5 & --debug=5 (an empty flag name is + not valid). ENHANCEMENTS: - Added "(DRY RUN)" info to the --debug=exit output line. - - Added a few extra long options to rrsync script, which will make BackupPC happier. + - Use usleep() for our msleep() function if it is available. + - Added a few extra long-option names to rrsync script, which will make + BackupPC happier. + - Made configure choose to use linux xattrs on netbsd (rather than not + supporting xattrs). + - Added -wo (write-only) option to rrsync support script. + - Misc. manpage tweaks. DEVELOPER RELATED: - Fixed a bug with the Makefile's use of INSTALL_STRIP. + - Improve a test in the suite that could get an erroneous timestamp error. - Tweaks for newer versions of git in the packaging tools. + - Improved the m4 generation rules and some autoconf idioms. @@ -3650,6 +3650,7 @@ Changes since 2.4.6: Partial Protocol History RELEASE DATE VER.

It can +copy locally, to/from another host over any remote shell, or to/from a +remote rsync daemon. It offers a large number of options that control +every aspect of its behavior and permit very flexible specification of the +set of files to be copied. It is famous for its delta\-transfer algorithm, +which reduces the amount of data sent over the network by sending only the +differences between the source files and the existing files in the +destination. Rsync is widely used for backups and mirroring and as an +improved copy command for everyday use. +.PP +Rsync finds files that need to be transferred using a \(dq\&quick check\(dq\& +algorithm (by default) that looks for files that have changed in size or +in last\-modified time. Any changes in the other preserved attributes (as +requested by options) are made on the destination file directly when the +quick check indicates that the file\(cq\&s data does not need to be updated. +.PP +Some of the additional features of rsync are: +.PP +.IP o +support for copying links, devices, owners, groups, and permissions +.IP o +exclude and exclude\-from options similar to GNU tar +.IP o +a CVS exclude mode for ignoring the same files that CVS would ignore +.IP o +can use any transparent remote shell, including ssh or rsh +.IP o +does not require super\-user privileges +.IP o +pipelining of file transfers to minimize latency costs +.IP o +support for anonymous or authenticated rsync daemons (ideal for +mirroring) + +.PP +.SH "GENERAL" + +.PP +Rsync copies files either to or from a remote host, or locally on the +current host (it does not support copying files between two remote hosts). +.PP +There are two different ways for rsync to contact a remote system: using a +remote\-shell program as the transport (such as ssh or rsh) or contacting an +rsync daemon directly via TCP. The remote\-shell transport is used whenever +the source or destination path contains a single colon (:) separator after +a host specification. Contacting an rsync daemon directly happens when the +source or destination path contains a double colon (::) separator after a +host specification, OR when an rsync:// URL is specified (see also the +\(dq\&USING RSYNC\-DAEMON FEATURES VIA A REMOTE\-SHELL CONNECTION\(dq\& section for +an exception to this latter rule). +.PP +As a special case, if a single source arg is specified without a +destination, the files are listed in an output format similar to \(dq\&ls \-l\(dq\&. +.PP +As expected, if neither the source or destination path specify a remote +host, the copy occurs locally (see also the \fB\-\-list\-only\fP option). +.PP +Rsync refers to the local side as the \(dq\&client\(dq\& and the remote side as the +\(dq\&server\(dq\&. Don\(cq\&t confuse \(dq\&server\(dq\& with an rsync daemon \-\- a daemon is always a +server, but a server can be either a daemon or a remote\-shell spawned process. +.PP +.SH "SETUP" + +.PP +See the file README for installation instructions. +.PP +Once installed, you can use rsync to any machine that you can access via +a remote shell (as well as some that you can access using the rsync +daemon\-mode protocol). For remote transfers, a modern rsync uses ssh +for its communications, but it may have been configured to use a +different remote shell by default, such as rsh or remsh. +.PP +You can also specify any remote shell you like, either by using the \fB\-e\fP +command line option, or by setting the RSYNC_RSH environment variable. +.PP +Note that rsync must be installed on both the source and destination +machines. +.PP +.SH "USAGE" + +.PP +You use rsync in the same way you use rcp. You must specify a source +and a destination, one of which may be remote. +.PP +Perhaps the best way to explain the syntax is with some examples: +.PP +.RS +\f(CWrsync \-t *.c foo:src/\fP +.RE + +.PP +This would transfer all files matching the pattern *.c from the +current directory to the directory src on the machine foo. If any of +the files already exist on the remote system then the rsync +remote\-update protocol is used to update the file by sending only the +differences in the data. Note that the expansion of wildcards on the +commandline (*.c) into a list of files is handled by the shell before +it runs rsync and not by rsync itself (exactly the same as all other +posix\-style programs). +.PP +.RS +\f(CWrsync \-avz foo:src/bar /data/tmp\fP +.RE + +.PP +This would recursively transfer all files from the directory src/bar on the +machine foo into the /data/tmp/bar directory on the local machine. The +files are transferred in \(dq\&archive\(dq\& mode, which ensures that symbolic +links, devices, attributes, permissions, ownerships, etc. are preserved +in the transfer. Additionally, compression will be used to reduce the +size of data portions of the transfer. +.PP +.RS +\f(CWrsync \-avz foo:src/bar/ /data/tmp\fP +.RE + +.PP +A trailing slash on the source changes this behavior to avoid creating an +additional directory level at the destination. You can think of a trailing +/ on a source as meaning \(dq\© the contents of this directory\(dq\& as opposed +to \(dq\© the directory by name\(dq\&, but in both cases the attributes of the +containing directory are transferred to the containing directory on the +destination. In other words, each of the following commands copies the +files in the same way, including their setting of the attributes of +/dest/foo: +.PP +.RS +\f(CWrsync \-av /src/foo /dest\fP +.br +\f(CWrsync \-av /src/foo/ /dest/foo\fP +.br +.RE + +.PP +Note also that host and module references don\(cq\&t require a trailing slash to +copy the contents of the default directory. For example, both of these +copy the remote directory\(cq\&s contents into \(dq\&/dest\(dq\&: +.PP +.RS +\f(CWrsync \-av host: /dest\fP +.br +\f(CWrsync \-av host::module /dest\fP +.br +.RE + +.PP +You can also use rsync in local\-only mode, where both the source and +destination don\(cq\&t have a \(cq\&:\(cq\& in the name. In this case it behaves like +an improved copy command. +.PP +Finally, you can list all the (listable) modules available from a +particular rsync daemon by leaving off the module name: +.PP +.RS +\f(CWrsync somehost.mydomain.com::\fP +.RE + +.PP +See the following section for more details. +.PP +.SH "ADVANCED USAGE" + +.PP +The syntax for requesting multiple files from a remote host is done by +specifying additional remote\-host args in the same style as the first, +or with the hostname omitted. For instance, all these work: +.PP +.RS +\f(CWrsync \-av host:file1 :file2 host:file{3,4} /dest/\fP +.br +\f(CWrsync \-av host::modname/file{1,2} host::modname/file3 /dest/\fP +.br +\f(CWrsync \-av host::modname/file1 ::modname/file{3,4}\fP +.RE + +.PP +Older versions of rsync required using quoted spaces in the SRC, like these +examples: +.PP +.RS +\f(CWrsync \-av host:'\&dir1/file1 dir2/file2'\& /dest\fP +.br +\f(CWrsync host::'\&modname/dir1/file1 modname/dir2/file2'\& /dest\fP +.RE + +.PP +This word\-splitting still works (by default) in the latest rsync, but is +not as easy to use as the first method. +.PP +If you need to transfer a filename that contains whitespace, you can either +specify the \fB\-\-protect\-args\fP (\fB\-s\fP) option, or you\(cq\&ll need to escape +the whitespace in a way that the remote shell will understand. For +instance: +.PP +.RS +\f(CWrsync \-av host:'\&file\e name\e with\e spaces'\& /dest\fP +.RE + +.PP +.SH "CONNECTING TO AN RSYNC DAEMON" + +.PP +It is also possible to use rsync without a remote shell as the transport. +In this case you will directly connect to a remote rsync daemon, typically +using TCP port 873. (This obviously requires the daemon to be running on +the remote system, so refer to the STARTING AN RSYNC DAEMON TO ACCEPT +CONNECTIONS section below for information on that.) +.PP +Using rsync in this way is the same as using it with a remote shell except +that: +.PP +.IP o +you either use a double colon :: instead of a single colon to +separate the hostname from the path, or you use an rsync:// URL. +.IP o +the first word of the \(dq\&path\(dq\& is actually a module name. +.IP o +the remote daemon may print a message of the day when you +connect. +.IP o +if you specify no path name on the remote daemon then the +list of accessible paths on the daemon will be shown. +.IP o +if you specify no local destination then a listing of the +specified files on the remote daemon is provided. +.IP o +you must not specify the \fB\-\-rsh\fP (\fB\-e\fP) option. + +.PP +An example that copies all the files in a remote module named \(dq\&src\(dq\&: +.PP +.nf + rsync \-av host::src /dest +.fi + +.PP +Some modules on the remote daemon may require authentication. If so, +you will receive a password prompt when you connect. You can avoid the +password prompt by setting the environment variable RSYNC_PASSWORD to +the password you want to use or using the \fB\-\-password\-file\fP option. This +may be useful when scripting rsync. +.PP +WARNING: On some systems environment variables are visible to all +users. On those systems using \fB\-\-password\-file\fP is recommended. +.PP +You may establish the connection via a web proxy by setting the +environment variable RSYNC_PROXY to a hostname:port pair pointing to +your web proxy. Note that your web proxy\(cq\&s configuration must support +proxy connections to port 873. +.PP +You may also establish a daemon connection using a program as a proxy by +setting the environment variable RSYNC_CONNECT_PROG to the commands you +wish to run in place of making a direct socket connection. The string may +contain the escape \(dq\&%H\(dq\& to represent the hostname specified in the rsync +command (so use \(dq\&%%\(dq\& if you need a single \(dq\&%\(dq\& in your string). For +example: +.PP +.nf + export RSYNC_CONNECT_PROG='\&ssh proxyhost nc %H 873'\& + rsync \-av targethost1::module/src/ /dest/ + rsync \-av rsync:://targethost2/module/src/ /dest/ +.fi + +.PP +The command specified above uses ssh to run nc (netcat) on a proxyhost, +which forwards all data to port 873 (the rsync daemon) on the targethost +(%H). +.PP +.SH "USING RSYNC\-DAEMON FEATURES VIA A REMOTE\-SHELL CONNECTION" + +.PP +It is sometimes useful to use various features of an rsync daemon (such as +named modules) without actually allowing any new socket connections into a +system (other than what is already required to allow remote\-shell access). +Rsync supports connecting to a host using a remote shell and then spawning +a single\-use \(dq\&daemon\(dq\& server that expects to read its config file in the +home dir of the remote user. This can be useful if you want to encrypt a +daemon\-style transfer\(cq\&s data, but since the daemon is started up fresh by +the remote user, you may not be able to use features such as chroot or +change the uid used by the daemon. (For another way to encrypt a daemon +transfer, consider using ssh to tunnel a local port to a remote machine and +configure a normal rsync daemon on that remote host to only allow +connections from \(dq\&localhost\(dq\&.) +.PP +From the user\(cq\&s perspective, a daemon transfer via a remote\-shell +connection uses nearly the same command\-line syntax as a normal +rsync\-daemon transfer, with the only exception being that you must +explicitly set the remote shell program on the command\-line with the +\fB\-\-rsh=COMMAND\fP option. (Setting the RSYNC_RSH in the environment +will not turn on this functionality.) For example: +.PP +.nf + rsync \-av \-\-rsh=ssh host::module /dest +.fi + +.PP +If you need to specify a different remote\-shell user, keep in mind that the +user@ prefix in front of the host is specifying the rsync\-user value (for a +module that requires user\-based authentication). This means that you must +give the \(cq\&\-l user\(cq\& option to ssh when specifying the remote\-shell, as in +this example that uses the short version of the \fB\-\-rsh\fP option: +.PP +.nf + rsync \-av \-e \(dq\&ssh \-l ssh\-user\(dq\& rsync\-user@host::module /dest +.fi + +.PP +The \(dq\&ssh\-user\(dq\& will be used at the ssh level; the \(dq\&rsync\-user\(dq\& will be +used to log\-in to the \(dq\&module\(dq\&. +.PP +.SH "STARTING AN RSYNC DAEMON TO ACCEPT CONNECTIONS" + +.PP +In order to connect to an rsync daemon, the remote system needs to have a +daemon already running (or it needs to have configured something like inetd +to spawn an rsync daemon for incoming connections on a particular port). +For full information on how to start a daemon that will handling incoming +socket connections, see the \fBrsyncd.conf\fP(5) man page \-\- that is the config +file for the daemon, and it contains the full details for how to run the +daemon (including stand\-alone and inetd configurations). +.PP +If you\(cq\&re using one of the remote\-shell transports for the transfer, there is +no need to manually start an rsync daemon. +.PP +.SH "SORTED TRANSFER ORDER" + +.PP +Rsync always sorts the specified filenames into its internal transfer list. +This handles the merging together of the contents of identically named +directories, makes it easy to remove duplicate filenames, and may confuse +someone when the files are transferred in a different order than what was +given on the command\-line. +.PP +If you need a particular file to be transferred prior to another, either +separate the files into different rsync calls, or consider using +\fB\-\-delay\-updates\fP (which doesn\(cq\&t affect the sorted transfer order, but +does make the final file\-updating phase happen much more rapidly). +.PP +.SH "EXAMPLES" + +.PP +Here are some examples of how I use rsync. +.PP +To backup my wife\(cq\&s home directory, which consists of large MS Word +files and mail folders, I use a cron job that runs +.PP +.RS +\f(CWrsync \-Cavz . arvidsjaur:backup\fP +.RE + +.PP +each night over a PPP connection to a duplicate directory on my machine +\(dq\&arvidsjaur\(dq\&. +.PP +To synchronize my samba source trees I use the following Makefile +targets: +.PP +.nf + get: + rsync \-avuzb \-\-exclude '\&*~'\& samba:samba/ . + put: + rsync \-Cavuzb . samba:samba/ + sync: get put +.fi + +.PP +this allows me to sync with a CVS directory at the other end of the +connection. I then do CVS operations on the remote machine, which saves a +lot of time as the remote CVS protocol isn\(cq\&t very efficient. +.PP +I mirror a directory between my \(dq\&old\(dq\& and \(dq\&new\(dq\& ftp sites with the +command: +.PP +\f(CWrsync \-az \-e ssh \-\-delete ~ftp/pub/samba nimbus:\(dq\&~ftp/pub/tridge\(dq\&\fP +.PP +This is launched from cron every few hours. +.PP +.SH "OPTIONS SUMMARY" + +.PP +Here is a short summary of the options available in rsync.

By default, rsync works silently. A +single \fB\-v\fP will give you information about what files are being +transferred and a brief summary at the end. Two \fB\-v\fP options will give you +information on what files are being skipped and slightly more +information at the end. More than two \fB\-v\fP options should only be used if +you are debugging rsync. +.IP +In a modern rsync, the \fB\-v\fP option is equivalent to the setting of groups +of \fB\-\-info\fP and \fB\-\-debug\fP options. You can choose to use these newer +options in addition to, or in place of using \fB\-\-verbose\fP, as any +fine\-grained settings override the implied settings of \fB\-v\fP. Both +\fB\-\-info\fP and \fB\-\-debug\fP have a way to ask for help that tells you +exactly what flags are set for each increase in verbosity. +.IP +However, do keep in mind that a daemon\(cq\&s \(dq\&max verbosity\(dq\& setting will limit how +high of a level the various individual flags can be set on the daemon side. +For instance, if the max is 2, then any info and/or debug flag that is set to +a higher value than what would be set by \fB\-vv\fP will be downgraded to the +\fB\-vv\fP level in the daemon\(cq\&s logging. +.IP +.IP "\fB\-\-info=FLAGS\fP" +This option lets you have fine\-grained control over the +information +output you want to see. An individual flag name may be followed by a level +number, with 0 meaning to silence that output, 1 being the default output +level, and higher numbers increasing the output of that flag (for those +that support higher levels). Use +\fB\-\-info=help\fP +to see all the available flag names, what they output, and what flag names +are added for each increase in the verbose level. Some examples: +.IP +.nf + rsync \-a \-\-info=progress2 src/ dest/ + rsync \-avv \-\-info=stats2,misc1,flist0 src/ dest/ +.fi + +.IP +Note that \fB\-\-info=name\fP\(cq\&s output is affected by the \fB\-\-out\-format\fP and +\fB\-\-itemize\-changes\fP (\fB\-i\fP) options. See those options for more +information on what is output and when. +.IP +This option was added to 3.1.0, so an older rsync on the server side might +reject your attempts at fine\-grained control (if one or more flags needed +to be send to the server and the server was too old to understand them). +See also the \(dq\&max verbosity\(dq\& caveat above when dealing with a daemon. +.IP +.IP "\fB\-\-debug=FLAGS\fP" +This option lets you have fine\-grained control over the debug +output you want to see. An individual flag name may be followed by a level +number, with 0 meaning to silence that output, 1 being the default output +level, and higher numbers increasing the output of that flag (for those +that support higher levels). Use +\fB\-\-debug=help\fP +to see all the available flag names, what they output, and what flag names +are added for each increase in the verbose level. Some examples: +.IP +.nf + rsync \-avvv \-\-debug=none src/ dest/ + rsync \-avA \-\-del \-\-debug=del2,acl src/ dest/ +.fi + +.IP +Note that some debug messages will only be output when \fB\-\-msgs2stderr\fP is +specified, especially those pertaining to I/O and buffer debugging. +.IP +This option was added to 3.1.0, so an older rsync on the server side might +reject your attempts at fine\-grained control (if one or more flags needed +to be send to the server and the server was too old to understand them). +See also the \(dq\&max verbosity\(dq\& caveat above when dealing with a daemon. +.IP +.IP "\fB\-\-msgs2stderr\fP" +This option changes rsync to send all its output +directly to stderr rather than to send messages to the client side via the +protocol (which normally outputs info messages via stdout). This is mainly +intended for debugging in order to avoid changing the data sent via the +protocol, since the extra protocol data can change what is being tested. +The option does not affect the remote side of a transfer without using +\fB\-\-remote\-option\fP \-\- e.g. \fB\-M\-\-msgs2stderr\fP. +Also keep in mind that a daemon connection does not have a stderr channel to send +messages back to the client side, so if you are doing any daemon\-transfer +debugging using this option, you should start up a daemon using \fB\-\-no\-detach\fP +so that you can see the stderr output on the daemon side. +.IP +This option has the side\-effect of making stderr output get line\-buffered so +that the merging of the output of 3 programs happens in a more readable manner. +.IP +.IP "\fB\-q, \-\-quiet\fP" +This option decreases the amount of information you +are given during the transfer, notably suppressing information messages +from the remote server. This option is useful when invoking rsync from +cron. +.IP +.IP "\fB\-\-no\-motd\fP" +This option affects the information that is output +by the client at the start of a daemon transfer. This suppresses the +message\-of\-the\-day (MOTD) text, but it also affects the list of modules +that the daemon sends in response to the \(dq\&rsync host::\(dq\& request (due to +a limitation in the rsync protocol), so omit this option if you want to +request the list of modules from the daemon. +.IP +.IP "\fB\-I, \-\-ignore\-times\fP" +Normally rsync will skip any files that are +already the same size and have the same modification timestamp. +This option turns off this \(dq\&quick check\(dq\& behavior, causing all files to +be updated. +.IP +.IP "\fB\-\-size\-only\fP" +This modifies rsync\(cq\&s \(dq\&quick check\(dq\& algorithm for +finding files that need to be transferred, changing it from the default of +transferring files with either a changed size or a changed last\-modified +time to just looking for files that have changed in size. This is useful +when starting to use rsync after using another mirroring system which may +not preserve timestamps exactly. +.IP +.IP "\fB\-\-modify\-window\fP" +When comparing two timestamps, rsync treats the +timestamps as being equal if they differ by no more than the modify\-window +value. This is normally 0 (for an exact match), but you may find it useful +to set this to a larger value in some situations. In particular, when +transferring to or from an MS Windows FAT filesystem (which represents +times with a 2\-second resolution), \fB\-\-modify\-window=1\fP is useful +(allowing times to differ by up to 1 second). +.IP +.IP "\fB\-c, \-\-checksum\fP" +This changes the way rsync checks if the files have +been changed and are in need of a transfer. Without this option, rsync +uses a \(dq\&quick check\(dq\& that (by default) checks if each file\(cq\&s size and time +of last modification match between the sender and receiver. This option +changes this to compare a 128\-bit checksum for each file that has a +matching size. Generating the checksums means that both sides will expend +a lot of disk I/O reading all the data in the files in the transfer (and +this is prior to any reading that will be done to transfer changed files), +so this can slow things down significantly. +.IP +The sending side generates its checksums while it is doing the file\-system +scan that builds the list of the available files. The receiver generates +its checksums when it is scanning for changed files, and will checksum any +file that has the same size as the corresponding sender\(cq\&s file: files with +either a changed size or a changed checksum are selected for transfer. +.IP +Note that rsync always verifies that each \fItransferred\fP file was +correctly reconstructed on the receiving side by checking a whole\-file +checksum that is generated as the file is transferred, but that +automatic after\-the\-transfer verification has nothing to do with this +option\(cq\&s before\-the\-transfer \(dq\&Does this file need to be updated?\(dq\& check. +.IP +For protocol 30 and beyond (first supported in 3.0.0), the checksum used is +MD5. For older protocols, the checksum used is MD4. +.IP +.IP "\fB\-a, \-\-archive\fP" +This is equivalent to \fB\-rlptgoD\fP. It is a quick +way of saying you want recursion and want to preserve almost +everything (with \-H being a notable omission). +The only exception to the above equivalence is when \fB\-\-files\-from\fP is +specified, in which case \fB\-r\fP is not implied. +.IP +Note that \fB\-a\fP \fBdoes not preserve hardlinks\fP, because +finding multiply\-linked files is expensive. You must separately +specify \fB\-H\fP. +.IP +.IP "\-\-no\-OPTION" +You may turn off one or more implied options by prefixing +the option name with \(dq\&no\-\(dq\&. Not all options may be prefixed with a \(dq\&no\-\(dq\&: +only options that are implied by other options (e.g. \fB\-\-no\-D\fP, +\fB\-\-no\-perms\fP) or have different defaults in various circumstances +(e.g. \fB\-\-no\-whole\-file\fP, \fB\-\-no\-blocking\-io\fP, \fB\-\-no\-dirs\fP). You may +specify either the short or the long option name after the \(dq\&no\-\(dq\& prefix +(e.g. \fB\-\-no\-R\fP is the same as \fB\-\-no\-relative\fP). +.IP +For example: if you want to use \fB\-a\fP (\fB\-\-archive\fP) but don\(cq\&t want +\fB\-o\fP (\fB\-\-owner\fP), instead of converting \fB\-a\fP into \fB\-rlptgD\fP, you +could specify \fB\-a \-\-no\-o\fP (or \fB\-a \-\-no\-owner\fP). +.IP +The order of the options is important: if you specify \fB\-\-no\-r \-a\fP, the +\fB\-r\fP option would end up being turned on, the opposite of \fB\-a \-\-no\-r\fP. +Note also that the side\-effects of the \fB\-\-files\-from\fP option are NOT +positional, as it affects the default state of several options and slightly +changes the meaning of \fB\-a\fP (see the \fB\-\-files\-from\fP option for more +details). +.IP +.IP "\fB\-r, \-\-recursive\fP" +This tells rsync to copy directories +recursively. See also \fB\-\-dirs\fP (\fB\-d\fP). +.IP +Beginning with rsync 3.0.0, the recursive algorithm used is now an +incremental scan that uses much less memory than before and begins the +transfer after the scanning of the first few directories have been +completed. This incremental scan only affects our recursion algorithm, and +does not change a non\-recursive transfer. It is also only possible when +both ends of the transfer are at least version 3.0.0. +.IP +Some options require rsync to know the full file list, so these options +disable the incremental recursion mode. These include: \fB\-\-delete\-before\fP, +\fB\-\-delete\-after\fP, \fB\-\-prune\-empty\-dirs\fP, and \fB\-\-delay\-updates\fP. +Because of this, the default delete mode when you specify \fB\-\-delete\fP is now +\fB\-\-delete\-during\fP when both ends of the connection are at least 3.0.0 +(use \fB\-\-del\fP or \fB\-\-delete\-during\fP to request this improved deletion mode +explicitly). See also the \fB\-\-delete\-delay\fP option that is a better choice +than using \fB\-\-delete\-after\fP. +.IP +Incremental recursion can be disabled using the \fB\-\-no\-inc\-recursive\fP +option or its shorter \fB\-\-no\-i\-r\fP alias. +.IP +.IP "\fB\-R, \-\-relative\fP" +Use relative paths. This means that the full path +names specified on the command line are sent to the server rather than +just the last parts of the filenames. This is particularly useful when +you want to send several different directories at the same time. For +example, if you used this command: +.IP +.RS +\f(CW rsync \-av /foo/bar/baz.c remote:/tmp/\fP +.RE + +.IP +\&... this would create a file named baz.c in /tmp/ on the remote +machine. If instead you used +.IP +.RS +\f(CW rsync \-avR /foo/bar/baz.c remote:/tmp/\fP +.RE + +.IP +then a file named /tmp/foo/bar/baz.c would be created on the remote +machine, preserving its full path. These extra path elements are called +\(dq\&implied directories\(dq\& (i.e. the \(dq\&foo\(dq\& and the \(dq\&foo/bar\(dq\& directories in the +above example). +.IP +Beginning with rsync 3.0.0, rsync always sends these implied directories as +real directories in the file list, even if a path element is really a +symlink on the sending side. This prevents some really unexpected +behaviors when copying the full path of a file that you didn\(cq\&t realize had +a symlink in its path. If you want to duplicate a server\-side symlink, +include both the symlink via its path, and referent directory via its real +path. If you\(cq\&re dealing with an older rsync on the sending side, you may +need to use the \fB\-\-no\-implied\-dirs\fP option. +.IP +It is also possible to limit the amount of path information that is sent as +implied directories for each path you specify. With a modern rsync on the +sending side (beginning with 2.6.7), you can insert a dot and a slash into +the source path, like this: +.IP +.RS +\f(CW rsync \-avR /foo/./bar/baz.c remote:/tmp/\fP +.RE + +.IP +That would create /tmp/bar/baz.c on the remote machine. (Note that the +dot must be followed by a slash, so \(dq\&/foo/.\(dq\& would not be abbreviated.) +For older rsync versions, you would need to use a chdir to limit the +source path. For example, when pushing files: +.IP +.RS +\f(CW (cd /foo; rsync \-avR bar/baz.c remote:/tmp/) \fP +.RE + +.IP +(Note that the parens put the two commands into a sub\-shell, so that the +\(dq\&cd\(dq\& command doesn\(cq\&t remain in effect for future commands.) +If you\(cq\&re pulling files from an older rsync, use this idiom (but only +for a non\-daemon transfer): +.IP +.RS +\f(CW rsync \-avR \-\-rsync\-path=\(dq\&cd /foo; rsync\(dq\& \e \fP +.br +\f(CW remote:bar/baz.c /tmp/\fP +.RE + +.IP +.IP "\fB\-\-no\-implied\-dirs\fP" +This option affects the default behavior of the +\fB\-\-relative\fP option. When it is specified, the attributes of the implied +directories from the source names are not included in the transfer. This +means that the corresponding path elements on the destination system are +left unchanged if they exist, and any missing implied directories are +created with default attributes. This even allows these implied path +elements to have big differences, such as being a symlink to a directory on +the receiving side. +.IP +For instance, if a command\-line arg or a files\-from entry told rsync to +transfer the file \(dq\&path/foo/file\(dq\&, the directories \(dq\&path\(dq\& and \(dq\&path/foo\(dq\& +are implied when \fB\-\-relative\fP is used. If \(dq\&path/foo\(dq\& is a symlink to +\(dq\&bar\(dq\& on the destination system, the receiving rsync would ordinarily +delete \(dq\&path/foo\(dq\&, recreate it as a directory, and receive the file into +the new directory. With \fB\-\-no\-implied\-dirs\fP, the receiving rsync updates +\(dq\&path/foo/file\(dq\& using the existing path elements, which means that the file +ends up being created in \(dq\&path/bar\(dq\&. Another way to accomplish this link +preservation is to use the \fB\-\-keep\-dirlinks\fP option (which will also +affect symlinks to directories in the rest of the transfer). +.IP +When pulling files from an rsync older than 3.0.0, you may need to use this +option if the sending side has a symlink in the path you request and you +wish the implied directories to be transferred as normal directories. +.IP +.IP "\fB\-b, \-\-backup\fP" +With this option, preexisting destination files are +renamed as each file is transferred or deleted. You can control where the +backup file goes and what (if any) suffix gets appended using the +\fB\-\-backup\-dir\fP and \fB\-\-suffix\fP options. +.IP +Note that if you don\(cq\&t specify \fB\-\-backup\-dir\fP, (1) the +\fB\-\-omit\-dir\-times\fP option will be implied, and (2) if \fB\-\-delete\fP is +also in effect (without \fB\-\-delete\-excluded\fP), rsync will add a \(dq\&protect\(dq\& +filter\-rule for the backup suffix to the end of all your existing excludes +(e.g. \fB\-f \(dq\&P *~\(dq\&\fP). This will prevent previously backed\-up files from being +deleted. Note that if you are supplying your own filter rules, you may +need to manually insert your own exclude/protect rule somewhere higher up +in the list so that it has a high enough priority to be effective (e.g., if +your rules specify a trailing inclusion/exclusion of \(cq\&*\(cq\&, the auto\-added +rule would never be reached). +.IP +.IP "\fB\-\-backup\-dir=DIR\fP" +In combination with the \fB\-\-backup\fP option, this +tells rsync to store all backups in the specified directory on the receiving +side. This can be used for incremental backups. You can additionally +specify a backup suffix using the \fB\-\-suffix\fP option +(otherwise the files backed up in the specified directory +will keep their original filenames). +.IP +Note that if you specify a relative path, the backup directory will be +relative to the destination directory, so you probably want to specify +either an absolute path or a path that starts with \(dq\&../\(dq\&. If an rsync +daemon is the receiver, the backup dir cannot go outside the module\(cq\&s path +hierarchy, so take extra care not to delete it or copy into it. +.IP +.IP "\fB\-\-suffix=SUFFIX\fP" +This option allows you to override the default +backup suffix used with the \fB\-\-backup\fP (\fB\-b\fP) option. The default suffix is a ~ +if no \-\fB\-backup\-dir\fP was specified, otherwise it is an empty string. +.IP +.IP "\fB\-u, \-\-update\fP" +This forces rsync to skip any files which exist on +the destination and have a modified time that is newer than the source +file. (If an existing destination file has a modification time equal to the +source file\(cq\&s, it will be updated if the sizes are different.) +.IP +Note that this does not affect the copying of dirs, symlinks, or other special +files. Also, a difference of file format between the sender and receiver +is always considered to be important enough for an update, no matter what +date is on the objects. In other words, if the source has a directory +where the destination has a file, the transfer would occur regardless of +the timestamps. +.IP +This option is a transfer rule, not an exclude, so it doesn\(cq\&t affect the +data that goes into the file\-lists, and thus it doesn\(cq\&t affect deletions. +It just limits the files that the receiver requests to be transferred. +.IP +.IP "\fB\-\-inplace\fP" +This option changes how rsync transfers a file when +its data needs to be updated: instead of the default method of creating +a new copy of the file and moving it into place when it is complete, rsync +instead writes the updated data directly to the destination file. +.IP +This has several effects: +.IP +.RS +.IP o +Hard links are not broken. This means the new data will be visible +through other hard links to the destination file. Moreover, attempts to +copy differing source files onto a multiply\-linked destination file will +result in a \(dq\&tug of war\(dq\& with the destination data changing back and forth. +.IP o +In\-use binaries cannot be updated (either the OS will prevent this from +happening, or binaries that attempt to swap\-in their data will misbehave or +crash). +.IP o +The file\(cq\&s data will be in an inconsistent state during the transfer +and will be left that way if the transfer is interrupted or if an update +fails. +.IP o +A file that rsync cannot write to cannot be updated. While a super user +can update any file, a normal user needs to be granted write permission for +the open of the file for writing to be successful. +.IP o +The efficiency of rsync\(cq\&s delta\-transfer algorithm may be reduced if +some data in the destination file is overwritten before it can be copied to +a position later in the file. This does not apply if you use \fB\-\-backup\fP, +since rsync is smart enough to use the backup file as the basis file for the +transfer. +.RE + +.IP +WARNING: you should not use this option to update files that are being +accessed by others, so be careful when choosing to use this for a copy. +.IP +This option is useful for transferring large files with block\-based changes +or appended data, and also on systems that are disk bound, not network +bound. It can also help keep a copy\-on\-write filesystem snapshot from +diverging the entire contents of a file that only has minor changes. +.IP +The option implies \fB\-\-partial\fP (since an interrupted transfer does not delete +the file), but conflicts with \fB\-\-partial\-dir\fP and \fB\-\-delay\-updates\fP. +Prior to rsync 2.6.4 \fB\-\-inplace\fP was also incompatible with \fB\-\-compare\-dest\fP +and \fB\-\-link\-dest\fP. +.IP +.IP "\fB\-\-append\fP" +This causes rsync to update a file by appending data onto +the end of the file, which presumes that the data that already exists on +the receiving side is identical with the start of the file on the sending +side. If a file needs to be transferred and its size on the receiver is +the same or longer than the size on the sender, the file is skipped. This +does not interfere with the updating of a file\(cq\&s non\-content attributes +(e.g. permissions, ownership, etc.) when the file does not need to be +transferred, nor does it affect the updating of any non\-regular files. +Implies \fB\-\-inplace\fP, +but does not conflict with \fB\-\-sparse\fP (since it is always extending a +file\(cq\&s length). +.IP +The use of \fB\-\-append\fP can be dangerous if you aren\(cq\&t 100% sure that the files +that are longer have only grown by the appending of data onto the end. You +should thus use include/exclude/filter rules to ensure that such a transfer is +only affecting files that you know to be growing via appended data. +.IP +.IP "\fB\-\-append\-verify\fP" +This works just like the \fB\-\-append\fP option, but +the existing data on the receiving side is included in the full\-file +checksum verification step, which will cause a file to be resent if the +final verification step fails (rsync uses a normal, non\-appending +\fB\-\-inplace\fP transfer for the resend). +.IP +Note: prior to rsync 3.0.0, the \fB\-\-append\fP option worked like +\fB\-\-append\-verify\fP, so if you are interacting with an older rsync (or the +transfer is using a protocol prior to 30), specifying either append option +will initiate an \fB\-\-append\-verify\fP transfer. +.IP +.IP "\fB\-d, \-\-dirs\fP" +Tell the sending side to include any directories that +are encountered. Unlike \fB\-\-recursive\fP, a directory\(cq\&s contents are not copied +unless the directory name specified is \(dq\&.\(dq\& or ends with a trailing slash +(e.g. \(dq\&.\(dq\&, \(dq\&dir/.\(dq\&, \(dq\&dir/\(dq\&, etc.). Without this option or the +\fB\-\-recursive\fP option, rsync will skip all directories it encounters (and +output a message to that effect for each one). If you specify both +\fB\-\-dirs\fP and \fB\-\-recursive\fP, \fB\-\-recursive\fP takes precedence. +.IP +The \fB\-\-dirs\fP option is implied by the \fB\-\-files\-from\fP option +or the \fB\-\-list\-only\fP option (including an implied +\fB\-\-list\-only\fP usage) if \fB\-\-recursive\fP wasn\(cq\&t specified (so that +directories are seen in the listing). Specify \fB\-\-no\-dirs\fP (or \fB\-\-no\-d\fP) +if you want to turn this off. +.IP +There is also a backward\-compatibility helper option, \fB\-\-old\-dirs\fP (or +\fB\-\-old\-d\fP) that tells rsync to use a hack of \(dq\&\-r \-\-exclude=\(cq\&/*/*\(cq\&\(dq\& to get +an older rsync to list a single directory without recursing. +.IP +.IP "\fB\-l, \-\-links\fP" +When symlinks are encountered, recreate the +symlink on the destination. +.IP +.IP "\fB\-L, \-\-copy\-links\fP" +When symlinks are encountered, the item that +they point to (the referent) is copied, rather than the symlink. In older +versions of rsync, this option also had the side\-effect of telling the +receiving side to follow symlinks, such as symlinks to directories. In a +modern rsync such as this one, you\(cq\&ll need to specify \fB\-\-keep\-dirlinks\fP (\fB\-K\fP) +to get this extra behavior. The only exception is when sending files to +an rsync that is too old to understand \fB\-K\fP \-\- in that case, the \fB\-L\fP option +will still have the side\-effect of \fB\-K\fP on that older receiving rsync. +.IP +.IP "\fB\-\-copy\-unsafe\-links\fP" +This tells rsync to copy the referent of +symbolic links that point outside the copied tree. Absolute symlinks +are also treated like ordinary files, and so are any symlinks in the +source path itself when \fB\-\-relative\fP is used. This option has no +additional effect if \fB\-\-copy\-links\fP was also specified. +.IP +.IP "\fB\-\-safe\-links\fP" +This tells rsync to ignore any symbolic links +which point outside the copied tree. All absolute symlinks are +also ignored. Using this option in conjunction with \fB\-\-relative\fP may +give unexpected results. +.IP +.IP "\fB\-\-munge\-links\fP" +This option tells rsync to (1) modify all symlinks on +the receiving side in a way that makes them unusable but recoverable (see +below), or (2) to unmunge symlinks on the sending side that had been stored in +a munged state. This is useful if you don\(cq\&t quite trust the source of the data +to not try to slip in a symlink to a unexpected place. +.IP +The way rsync disables the use of symlinks is to prefix each one with the +string \(dq\&/rsyncd\-munged/\(dq\&. This prevents the links from being used as long as +that directory does not exist. When this option is enabled, rsync will refuse +to run if that path is a directory or a symlink to a directory. +.IP +The option only affects the client side of the transfer, so if you need it to +affect the server, specify it via \fB\-\-remote\-option\fP. (Note that in a local +transfer, the client side is the sender.) +.IP +This option has no affect on a daemon, since the daemon configures whether it +wants munged symlinks via its \(dq\&munge symlinks\(dq\& parameter. See also the +\(dq\&munge\-symlinks\(dq\& perl script in the support directory of the source code. +.IP +.IP "\fB\-k, \-\-copy\-dirlinks\fP" +This option causes the sending side to treat +a symlink to a directory as though it were a real directory. This is +useful if you don\(cq\&t want symlinks to non\-directories to be affected, as +they would be using \fB\-\-copy\-links\fP. +.IP +Without this option, if the sending side has replaced a directory with a +symlink to a directory, the receiving side will delete anything that is in +the way of the new symlink, including a directory hierarchy (as long as +\fB\-\-force\fP or \fB\-\-delete\fP is in effect). +.IP +See also \fB\-\-keep\-dirlinks\fP for an analogous option for the receiving +side. +.IP +\fB\-\-copy\-dirlinks\fP applies to all symlinks to directories in the source. If +you want to follow only a few specified symlinks, a trick you can use is to +pass them as additional source args with a trailing slash, using \fB\-\-relative\fP +to make the paths match up right. For example: +.IP +.RS +\f(CWrsync \-r \-\-relative src/./ src/./follow\-me/ dest/\fP +.RE + +.IP +This works because rsync calls \fBlstat\fP(2) on the source arg as given, and the +trailing slash makes \fBlstat\fP(2) follow the symlink, giving rise to a directory +in the file\-list which overrides the symlink found during the scan of \(dq\&src/./\(dq\&. +.IP +.IP "\fB\-K, \-\-keep\-dirlinks\fP" +This option causes the receiving side to treat +a symlink to a directory as though it were a real directory, but only if it +matches a real directory from the sender. Without this option, the +receiver\(cq\&s symlink would be deleted and replaced with a real directory. +.IP +For example, suppose you transfer a directory \(dq\&foo\(dq\& that contains a file +\(dq\&file\(dq\&, but \(dq\&foo\(dq\& is a symlink to directory \(dq\&bar\(dq\& on the receiver. Without +\fB\-\-keep\-dirlinks\fP, the receiver deletes symlink \(dq\&foo\(dq\&, recreates it as a +directory, and receives the file into the new directory. With +\fB\-\-keep\-dirlinks\fP, the receiver keeps the symlink and \(dq\&file\(dq\& ends up in +\(dq\&bar\(dq\&. +.IP +One note of caution: if you use \fB\-\-keep\-dirlinks\fP, you must trust all +the symlinks in the copy! If it is possible for an untrusted user to +create their own symlink to any directory, the user could then (on a +subsequent copy) replace the symlink with a real directory and affect the +content of whatever directory the symlink references. For backup copies, +you are better off using something like a bind mount instead of a symlink +to modify your receiving hierarchy. +.IP +See also \fB\-\-copy\-dirlinks\fP for an analogous option for the sending side. +.IP +.IP "\fB\-H, \-\-hard\-links\fP" +This tells rsync to look for hard\-linked files in +the source and link together the corresponding files on the destination. +Without this option, hard\-linked files in the source are treated +as though they were separate files. +.IP +This option does NOT necessarily ensure that the pattern of hard links on the +destination exactly matches that on the source. Cases in which the +destination may end up with extra hard links include the following: +.IP +.RS +.IP o +If the destination contains extraneous hard\-links (more linking than +what is present in the source file list), the copying algorithm will not +break them explicitly. However, if one or more of the paths have content +differences, the normal file\-update process will break those extra links +(unless you are using the \fB\-\-inplace\fP option). +.IP o +If you specify a \fB\-\-link\-dest\fP directory that contains hard links, +the linking of the destination files against the \fB\-\-link\-dest\fP files can +cause some paths in the destination to become linked together due to the +\fB\-\-link\-dest\fP associations. +.RE + +.IP +Note that rsync can only detect hard links between files that are inside +the transfer set. If rsync updates a file that has extra hard\-link +connections to files outside the transfer, that linkage will be broken. If +you are tempted to use the \fB\-\-inplace\fP option to avoid this breakage, be +very careful that you know how your files are being updated so that you are +certain that no unintended changes happen due to lingering hard links (and +see the \fB\-\-inplace\fP option for more caveats). +.IP +If incremental recursion is active (see \fB\-\-recursive\fP), rsync may transfer +a missing hard\-linked file before it finds that another link for that contents +exists elsewhere in the hierarchy. This does not affect the accuracy of +the transfer (i.e. which files are hard\-linked together), just its efficiency +(i.e. copying the data for a new, early copy of a hard\-linked file that could +have been found later in the transfer in another member of the hard\-linked +set of files). One way to avoid this inefficiency is to disable +incremental recursion using the \fB\-\-no\-inc\-recursive\fP option. +.IP +.IP "\fB\-p, \-\-perms\fP" +This option causes the receiving rsync to set the +destination permissions to be the same as the source permissions. (See +also the \fB\-\-chmod\fP option for a way to modify what rsync considers to +be the source permissions.) +.IP +When this option is \fIoff\fP, permissions are set as follows: +.IP +.RS +.IP o +Existing files (including updated files) retain their existing +permissions, though the \fB\-\-executability\fP option might change just +the execute permission for the file. +.IP o +New files get their \(dq\&normal\(dq\& permission bits set to the source +file\(cq\&s permissions masked with the receiving directory\(cq\&s default +permissions (either the receiving process\(cq\&s umask, or the permissions +specified via the destination directory\(cq\&s default ACL), and +their special permission bits disabled except in the case where a new +directory inherits a setgid bit from its parent directory. +.RE + +.IP +Thus, when \fB\-\-perms\fP and \fB\-\-executability\fP are both disabled, +rsync\(cq\&s behavior is the same as that of other file\-copy utilities, +such as \fBcp\fP(1) and \fBtar\fP(1). +.IP +In summary: to give destination files (both old and new) the source +permissions, use \fB\-\-perms\fP. To give new files the destination\-default +permissions (while leaving existing files unchanged), make sure that the +\fB\-\-perms\fP option is off and use \fB\-\-chmod=ugo=rwX\fP (which ensures that +all non\-masked bits get enabled). If you\(cq\&d care to make this latter +behavior easier to type, you could define a popt alias for it, such as +putting this line in the file ~/.popt (the following defines the \fB\-Z\fP option, +and includes \-\-no\-g to use the default group of the destination dir): +.IP +.RS +\f(CW rsync alias \-Z \-\-no\-p \-\-no\-g \-\-chmod=ugo=rwX\fP +.RE + +.IP +You could then use this new option in a command such as this one: +.IP +.RS +\f(CW rsync \-avZ src/ dest/\fP +.RE + +.IP +(Caveat: make sure that \fB\-a\fP does not follow \fB\-Z\fP, or it will re\-enable +the two \(dq\&\-\-no\-*\(dq\& options mentioned above.) +.IP +The preservation of the destination\(cq\&s setgid bit on newly\-created +directories when \fB\-\-perms\fP is off was added in rsync 2.6.7. Older rsync +versions erroneously preserved the three special permission bits for +newly\-created files when \fB\-\-perms\fP was off, while overriding the +destination\(cq\&s setgid bit setting on a newly\-created directory. Default ACL +observance was added to the ACL patch for rsync 2.6.7, so older (or +non\-ACL\-enabled) rsyncs use the umask even if default ACLs are present. +(Keep in mind that it is the version of the receiving rsync that affects +these behaviors.) +.IP +.IP "\fB\-E, \-\-executability\fP" +This option causes rsync to preserve the +executability (or non\-executability) of regular files when \fB\-\-perms\fP is +not enabled. A regular file is considered to be executable if at least one +\(cq\&x\(cq\& is turned on in its permissions. When an existing destination file\(cq\&s +executability differs from that of the corresponding source file, rsync +modifies the destination file\(cq\&s permissions as follows: +.IP +.RS +.IP o +To make a file non\-executable, rsync turns off all its \(cq\&x\(cq\& +permissions. +.IP o +To make a file executable, rsync turns on each \(cq\&x\(cq\& permission that +has a corresponding \(cq\&r\(cq\& permission enabled. +.RE + +.IP +If \fB\-\-perms\fP is enabled, this option is ignored. +.IP +.IP "\fB\-A, \-\-acls\fP" +This option causes rsync to update the destination +ACLs to be the same as the source ACLs. +The option also implies \fB\-\-perms\fP. +.IP +The source and destination systems must have compatible ACL entries for this +option to work properly. See the \fB\-\-fake\-super\fP option for a way to backup +and restore ACLs that are not compatible. +.IP +.IP "\fB\-X, \-\-xattrs\fP" +This option causes rsync to update the destination +extended attributes to be the same as the source ones. +.IP +For systems that support extended\-attribute namespaces, a copy being done by a +super\-user copies all namespaces except system.*. A normal user only copies +the user.* namespace. To be able to backup and restore non\-user namespaces as +a normal user, see the \fB\-\-fake\-super\fP option. +.IP +Note that this option does not copy rsyncs special xattr values (e.g. those +used by \fB\-\-fake\-super\fP) unless you repeat the option (e.g. \-XX). This +\(dq\© all xattrs\(dq\& mode cannot be used with \fB\-\-fake\-super\fP. +.IP +.IP "\fB\-\-chmod\fP" +This option tells rsync to apply one or more +comma\-separated \(dq\&chmod\(dq\& modes to the permission of the files in the +transfer. The resulting value is treated as though it were the permissions +that the sending side supplied for the file, which means that this option +can seem to have no effect on existing files if \fB\-\-perms\fP is not enabled. +.IP +In addition to the normal parsing rules specified in the \fBchmod\fP(1) +manpage, you can specify an item that should only apply to a directory by +prefixing it with a \(cq\&D\(cq\&, or specify an item that should only apply to a +file by prefixing it with a \(cq\&F\(cq\&. For example, the following will ensure +that all directories get marked set\-gid, that no files are other\-writable, +that both are user\-writable and group\-writable, and that both have +consistent executability across all bits: +.IP +.RS +\-\-chmod=Dg+s,ug+w,Fo\-w,+X +.RE + +.IP +Using octal mode numbers is also allowed: +.IP +.RS +\-\-chmod=D2775,F664 +.RE + +.IP +It is also legal to specify multiple \fB\-\-chmod\fP options, as each +additional option is just appended to the list of changes to make. +.IP +See the \fB\-\-perms\fP and \fB\-\-executability\fP options for how the resulting +permission value can be applied to the files in the transfer. +.IP +.IP "\fB\-o, \-\-owner\fP" +This option causes rsync to set the owner of the +destination file to be the same as the source file, but only if the +receiving rsync is being run as the super\-user (see also the \fB\-\-super\fP +and \fB\-\-fake\-super\fP options). +Without this option, the owner of new and/or transferred files are set to +the invoking user on the receiving side. +.IP +The preservation of ownership will associate matching names by default, but +may fall back to using the ID number in some circumstances (see also the +\fB\-\-numeric\-ids\fP option for a full discussion). +.IP +.IP "\fB\-g, \-\-group\fP" +This option causes rsync to set the group of the +destination file to be the same as the source file. If the receiving +program is not running as the super\-user (or if \fB\-\-no\-super\fP was +specified), only groups that the invoking user on the receiving side +is a member of will be preserved. +Without this option, the group is set to the default group of the invoking +user on the receiving side. +.IP +The preservation of group information will associate matching names by +default, but may fall back to using the ID number in some circumstances +(see also the \fB\-\-numeric\-ids\fP option for a full discussion). +.IP +.IP "\fB\-\-devices\fP" +This option causes rsync to transfer character and +block device files to the remote system to recreate these devices. +This option has no effect if the receiving rsync is not run as the +super\-user (see also the \fB\-\-super\fP and \fB\-\-fake\-super\fP options). +.IP +.IP "\fB\-\-specials\fP" +This option causes rsync to transfer special files +such as named sockets and fifos. +.IP +.IP "\fB\-D\fP" +The \fB\-D\fP option is equivalent to \fB\-\-devices\fP \fB\-\-specials\fP. +.IP +.IP "\fB\-t, \-\-times\fP" +This tells rsync to transfer modification times along +with the files and update them on the remote system. Note that if this +option is not used, the optimization that excludes files that have not been +modified cannot be effective; in other words, a missing \fB\-t\fP or \fB\-a\fP will +cause the next transfer to behave as if it used \fB\-I\fP, causing all files to be +updated (though rsync\(cq\&s delta\-transfer algorithm will make the update fairly efficient +if the files haven\(cq\&t actually changed, you\(cq\&re much better off using \fB\-t\fP). +.IP +.IP "\fB\-O, \-\-omit\-dir\-times\fP" +This tells rsync to omit directories when +it is preserving modification times (see \fB\-\-times\fP). If NFS is sharing +the directories on the receiving side, it is a good idea to use \fB\-O\fP. +This option is inferred if you use \fB\-\-backup\fP without \fB\-\-backup\-dir\fP. +.IP +This option also has the side\-effect of avoiding early creation of directories +in incremental recursion copies. The default \fB\-\-inc\-recursive\fP copying +normally does an early\-create pass of all the sub\-directories in a parent +directory in order for it to be able to then set the modify time of the parent +directory right away (without having to delay that until a bunch of recursive +copying has finished). This early\-create idiom is not necessary if directory +modify times are not being preserved, so it is skipped. Since early\-create +directories don\(cq\&t have accurate mode, mtime, or ownership, the use of this +option can help when someone wants to avoid these partially\-finished +directories. +.IP +.IP "\fB\-J, \-\-omit\-link\-times\fP" +This tells rsync to omit symlinks when +it is preserving modification times (see \fB\-\-times\fP). +.IP +.IP "\fB\-\-super\fP" +This tells the receiving side to attempt super\-user +activities even if the receiving rsync wasn\(cq\&t run by the super\-user. These +activities include: preserving users via the \fB\-\-owner\fP option, preserving +all groups (not just the current user\(cq\&s groups) via the \fB\-\-groups\fP +option, and copying devices via the \fB\-\-devices\fP option. This is useful +for systems that allow such activities without being the super\-user, and +also for ensuring that you will get errors if the receiving side isn\(cq\&t +being run as the super\-user. To turn off super\-user activities, the +super\-user can use \fB\-\-no\-super\fP. +.IP +.IP "\fB\-\-fake\-super\fP" +When this option is enabled, rsync simulates +super\-user activities by saving/restoring the privileged attributes via +special extended attributes that are attached to each file (as needed). This +includes the file\(cq\&s owner and group (if it is not the default), the file\(cq\&s +device info (device & special files are created as empty text files), and +any permission bits that we won\(cq\&t allow to be set on the real file (e.g. +the real file gets u\-s,g\-s,o\-t for safety) or that would limit the owner\(cq\&s +access (since the real super\-user can always access/change a file, the +files we create can always be accessed/changed by the creating user). +This option also handles ACLs (if \fB\-\-acls\fP was specified) and non\-user +extended attributes (if \fB\-\-xattrs\fP was specified). +.IP +This is a good way to backup data without using a super\-user, and to store +ACLs from incompatible systems. +.IP +The \fB\-\-fake\-super\fP option only affects the side where the option is used. +To affect the remote side of a remote\-shell connection, use the +\fB\-\-remote\-option\fP (\fB\-M\fP) option: +.IP +.RS +\f(CW rsync \-av \-M\-\-fake\-super /src/ host:/dest/\fP +.RE + +.IP +For a local copy, this option affects both the source and the destination. +If you wish a local copy to enable this option just for the destination +files, specify \fB\-M\-\-fake\-super\fP. If you wish a local copy to enable +this option just for the source files, combine \fB\-\-fake\-super\fP with +\fB\-M\-\-super\fP. +.IP +This option is overridden by both \fB\-\-super\fP and \fB\-\-no\-super\fP. +.IP +See also the \(dq\&fake super\(dq\& setting in the daemon\(cq\&s rsyncd.conf file. +.IP +.IP "\fB\-S, \-\-sparse\fP" +Try to handle sparse files efficiently so they take +up less space on the destination. Conflicts with \fB\-\-inplace\fP because it\(cq\&s +not possible to overwrite data in a sparse fashion. +.IP +.IP "\fB\-\-preallocate\fP" +This tells the receiver to allocate each destination +file to its eventual size before writing data to the file. Rsync will only use +the real filesystem\-level preallocation support provided by Linux\(cq\&s +\fBfallocate\fP(2) system call or Cygwin\(cq\&s \fBposix_fallocate\fP(3), not the slow +glibc implementation that writes a zero byte into each block. +.IP +Without this option, larger files may not be entirely contiguous on the +filesystem, but with this option rsync will probably copy more slowly. If the +destination is not an extent\-supporting filesystem (such as ext4, xfs, NTFS, +etc.), this option may have no positive effect at all. +.IP +.IP "\fB\-n, \-\-dry\-run\fP" +This makes rsync perform a trial run that doesn\(cq\&t +make any changes (and produces mostly the same output as a real run). It +is most commonly used in combination with the \fB\-v, \-\-verbose\fP and/or +\fB\-i, \-\-itemize\-changes\fP options to see what an rsync command is going +to do before one actually runs it. +.IP +The output of \fB\-\-itemize\-changes\fP is supposed to be exactly the same on a +dry run and a subsequent real run (barring intentional trickery and system +call failures); if it isn\(cq\&t, that\(cq\&s a bug. Other output should be mostly +unchanged, but may differ in some areas. Notably, a dry run does not +send the actual data for file transfers, so \fB\-\-progress\fP has no effect, +the \(dq\&bytes sent\(dq\&, \(dq\&bytes received\(dq\&, \(dq\&literal data\(dq\&, and \(dq\&matched data\(dq\& +statistics are too small, and the \(dq\&speedup\(dq\& value is equivalent to a run +where no file transfers were needed. +.IP +.IP "\fB\-W, \-\-whole\-file\fP" +With this option rsync\(cq\&s delta\-transfer algorithm +is not used and the whole file is sent as\-is instead. The transfer may be +faster if this option is used when the bandwidth between the source and +destination machines is higher than the bandwidth to disk (especially when the +\(dq\&disk\(dq\& is actually a networked filesystem). This is the default when both +the source and destination are specified as local paths, but only if no +batch\-writing option is in effect. +.IP +.IP "\fB\-x, \-\-one\-file\-system\fP" +This tells rsync to avoid crossing a +filesystem boundary when recursing. This does not limit the user\(cq\&s ability +to specify items to copy from multiple filesystems, just rsync\(cq\&s recursion +through the hierarchy of each directory that the user specified, and also +the analogous recursion on the receiving side during deletion. Also keep +in mind that rsync treats a \(dq\&bind\(dq\& mount to the same device as being on the +same filesystem. +.IP +If this option is repeated, rsync omits all mount\-point directories from +the copy. Otherwise, it includes an empty directory at each mount\-point it +encounters (using the attributes of the mounted directory because those of +the underlying mount\-point directory are inaccessible). +.IP +If rsync has been told to collapse symlinks (via \fB\-\-copy\-links\fP or +\fB\-\-copy\-unsafe\-links\fP), a symlink to a directory on another device is +treated like a mount\-point. Symlinks to non\-directories are unaffected +by this option. +.IP +.IP "\fB\-\-existing, \-\-ignore\-non\-existing\fP" +This tells rsync to skip +creating files (including directories) that do not exist +yet on the destination. If this option is +combined with the \fB\-\-ignore\-existing\fP option, no files will be updated +(which can be useful if all you want to do is delete extraneous files). +.IP +This option is a transfer rule, not an exclude, so it doesn\(cq\&t affect the +data that goes into the file\-lists, and thus it doesn\(cq\&t affect deletions. +It just limits the files that the receiver requests to be transferred. +.IP +.IP "\fB\-\-ignore\-existing\fP" +This tells rsync to skip updating files that +already exist on the destination (this does \fInot\fP ignore existing +directories, or nothing would get done). See also \fB\-\-existing\fP. +.IP +This option is a transfer rule, not an exclude, so it doesn\(cq\&t affect the +data that goes into the file\-lists, and thus it doesn\(cq\&t affect deletions. +It just limits the files that the receiver requests to be transferred. +.IP +This option can be useful for those doing backups using the \fB\-\-link\-dest\fP +option when they need to continue a backup run that got interrupted. Since +a \fB\-\-link\-dest\fP run is copied into a new directory hierarchy (when it is +used properly), using \fB\-\-ignore existing\fP will ensure that the +already\-handled files don\(cq\&t get tweaked (which avoids a change in +permissions on the hard\-linked files). This does mean that this option +is only looking at the existing files in the destination hierarchy itself. +.IP +.IP "\fB\-\-remove\-source\-files\fP" +This tells rsync to remove from the sending +side the files (meaning non\-directories) that are a part of the transfer +and have been successfully duplicated on the receiving side. +.IP +Note that you should only use this option on source files that are quiescent. +If you are using this to move files that show up in a particular directory over +to another host, make sure that the finished files get renamed into the source +directory, not directly written into it, so that rsync can\(cq\&t possibly transfer +a file that is not yet fully written. If you can\(cq\&t first write the files into +a different directory, you should use a naming idiom that lets rsync avoid +transferring files that are not yet finished (e.g. name the file \(dq\&foo.new\(dq\& when +it is written, rename it to \(dq\&foo\(dq\& when it is done, and then use the option +\fB\-\-exclude='\&*.new'\&\fP for the rsync transfer). +.IP +Starting with 3.1.0, rsync will skip the sender\-side removal (and output an +error) if the file\(cq\&s size or modify time has not stayed unchanged. +.IP +.IP "\fB\-\-delete\fP" +This tells rsync to delete extraneous files from the +receiving side (ones that aren\(cq\&t on the sending side), but only for the +directories that are being synchronized. You must have asked rsync to +send the whole directory (e.g. \(dq\&dir\(dq\& or \(dq\&dir/\(dq\&) without using a wildcard +for the directory\(cq\&s contents (e.g. \(dq\&dir/*\(dq\&) since the wildcard is expanded +by the shell and rsync thus gets a request to transfer individual files, not +the files\(cq\& parent directory. Files that are excluded from the transfer are +also excluded from being deleted unless you use the \fB\-\-delete\-excluded\fP +option or mark the rules as only matching on the sending side (see the +include/exclude modifiers in the FILTER RULES section). +.IP +Prior to rsync 2.6.7, this option would have no effect unless \fB\-\-recursive\fP +was enabled. Beginning with 2.6.7, deletions will also occur when \fB\-\-dirs\fP +(\fB\-d\fP) is enabled, but only for directories whose contents are being copied. +.IP +This option can be dangerous if used incorrectly! It is a very good idea to +first try a run using the \fB\-\-dry\-run\fP option (\fB\-n\fP) to see what files are +going to be deleted. +.IP +If the sending side detects any I/O errors, then the deletion of any +files at the destination will be automatically disabled. This is to +prevent temporary filesystem failures (such as NFS errors) on the +sending side from causing a massive deletion of files on the +destination. You can override this with the \fB\-\-ignore\-errors\fP option. +.IP +The \fB\-\-delete\fP option may be combined with one of the \-\-delete\-WHEN options +without conflict, as well as \fB\-\-delete\-excluded\fP. However, if none of the +\-\-delete\-WHEN options are specified, rsync will choose the +\fB\-\-delete\-during\fP algorithm when talking to rsync 3.0.0 or newer, and +the \fB\-\-delete\-before\fP algorithm when talking to an older rsync. See also +\fB\-\-delete\-delay\fP and \fB\-\-delete\-after\fP. +.IP +.IP "\fB\-\-delete\-before\fP" +Request that the file\-deletions on the receiving +side be done before the transfer starts. +See \fB\-\-delete\fP (which is implied) for more details on file\-deletion. +.IP +Deleting before the transfer is helpful if the filesystem is tight for space +and removing extraneous files would help to make the transfer possible. +However, it does introduce a delay before the start of the transfer, +and this delay might cause the transfer to timeout (if \fB\-\-timeout\fP was +specified). It also forces rsync to use the old, non\-incremental recursion +algorithm that requires rsync to scan all the files in the transfer into +memory at once (see \fB\-\-recursive\fP). +.IP +.IP "\fB\-\-delete\-during, \-\-del\fP" +Request that the file\-deletions on the +receiving side be done incrementally as the transfer happens. The +per\-directory delete scan is done right before each directory is checked +for updates, so it behaves like a more efficient \fB\-\-delete\-before\fP, +including doing the deletions prior to any per\-directory filter files +being updated. This option was first added in rsync version 2.6.4. +See \fB\-\-delete\fP (which is implied) for more details on file\-deletion. +.IP +.IP "\fB\-\-delete\-delay\fP" +Request that the file\-deletions on the receiving +side be computed during the transfer (like \fB\-\-delete\-during\fP), and then +removed after the transfer completes. This is useful when combined with +\fB\-\-delay\-updates\fP and/or \fB\-\-fuzzy\fP, and is more efficient than using +\fB\-\-delete\-after\fP (but can behave differently, since \fB\-\-delete\-after\fP +computes the deletions in a separate pass after all updates are done). +If the number of removed files overflows an internal buffer, a +temporary file will be created on the receiving side to hold the names (it +is removed while open, so you shouldn\(cq\&t see it during the transfer). If +the creation of the temporary file fails, rsync will try to fall back to +using \fB\-\-delete\-after\fP (which it cannot do if \fB\-\-recursive\fP is doing an +incremental scan). +See \fB\-\-delete\fP (which is implied) for more details on file\-deletion. +.IP +.IP "\fB\-\-delete\-after\fP" +Request that the file\-deletions on the receiving +side be done after the transfer has completed. This is useful if you +are sending new per\-directory merge files as a part of the transfer and +you want their exclusions to take effect for the delete phase of the +current transfer. It also forces rsync to use the old, non\-incremental +recursion algorithm that requires rsync to scan all the files in the +transfer into memory at once (see \fB\-\-recursive\fP). +See \fB\-\-delete\fP (which is implied) for more details on file\-deletion. +.IP +.IP "\fB\-\-delete\-excluded\fP" +In addition to deleting the files on the +receiving side that are not on the sending side, this tells rsync to also +delete any files on the receiving side that are excluded (see \fB\-\-exclude\fP). +See the FILTER RULES section for a way to make individual exclusions behave +this way on the receiver, and for a way to protect files from +\fB\-\-delete\-excluded\fP. +See \fB\-\-delete\fP (which is implied) for more details on file\-deletion. +.IP +.IP "\fB\-\-ignore\-missing\-args\fP" +When rsync is first processing the explicitly +requested source files (e.g. command\-line arguments or \fB\-\-files\-from\fP +entries), it is normally an error if the file cannot be found. This option +suppresses that error, and does not try to transfer the file. This does not +affect subsequent vanished\-file errors if a file was initially found to be +present and later is no longer there. +.IP +.IP "\fB\-\-delete\-missing\-args\fP" +This option takes the behavior of (the implied) +\fB\-\-ignore\-missing\-args\fP option a step farther: each missing arg will become +a deletion request of the corresponding destination file on the receiving side +(should it exist). If the destination file is a non\-empty directory, it will +only be successfully deleted if \-\-force or \-\-delete are in effect. Other than +that, this option is independent of any other type of delete processing. +.IP +The missing source files are represented by special file\-list entries which +display as a \(dq\&*missing\(dq\& entry in the \fB\-\-list\-only\fP output. +.IP +.IP "\fB\-\-ignore\-errors\fP" +Tells \fB\-\-delete\fP to go ahead and delete files +even when there are I/O errors. +.IP +.IP "\fB\-\-force\fP" +This option tells rsync to delete a non\-empty directory +when it is to be replaced by a non\-directory. This is only relevant if +deletions are not active (see \fB\-\-delete\fP for details). +.IP +Note for older rsync versions: \fB\-\-force\fP used to still be required when +using \fB\-\-delete\-after\fP, and it used to be non\-functional unless the +\fB\-\-recursive\fP option was also enabled. +.IP +.IP "\fB\-\-max\-delete=NUM\fP" +This tells rsync not to delete more than NUM +files or directories. If that limit is exceeded, all further deletions are +skipped through the end of the transfer. At the end, rsync outputs a warning +(including a count of the skipped deletions) and exits with an error code +of 25 (unless some more important error condition also occurred). +.IP +Beginning with version 3.0.0, you may specify \fB\-\-max\-delete=0\fP to be warned +about any extraneous files in the destination without removing any of them. +Older clients interpreted this as \(dq\&unlimited\(dq\&, so if you don\(cq\&t know what +version the client is, you can use the less obvious \fB\-\-max\-delete=\-1\fP as +a backward\-compatible way to specify that no deletions be allowed (though +really old versions didn\(cq\&t warn when the limit was exceeded). +.IP +.IP "\fB\-\-max\-size=SIZE\fP" +This tells rsync to avoid transferring any +file that is larger than the specified SIZE. The SIZE value can be +suffixed with a string to indicate a size multiplier, and +may be a fractional value (e.g. \(dq\&\fB\-\-max\-size=1.5m\fP\(dq\&). +.IP +This option is a transfer rule, not an exclude, so it doesn\(cq\&t affect the +data that goes into the file\-lists, and thus it doesn\(cq\&t affect deletions. +It just limits the files that the receiver requests to be transferred. +.IP +The suffixes are as follows: \(dq\&K\(dq\& (or \(dq\&KiB\(dq\&) is a kibibyte (1024), +\(dq\&M\(dq\& (or \(dq\&MiB\(dq\&) is a mebibyte (1024*1024), and \(dq\&G\(dq\& (or \(dq\&GiB\(dq\&) is a +gibibyte (1024*1024*1024). +If you want the multiplier to be 1000 instead of 1024, use \(dq\&KB\(dq\&, +\(dq\&MB\(dq\&, or \(dq\&GB\(dq\&. (Note: lower\-case is also accepted for all values.) +Finally, if the suffix ends in either \(dq\&+1\(dq\& or \(dq\&\-1\(dq\&, the value will +be offset by one byte in the indicated direction. +.IP +Examples: \-\-max\-size=1.5mb\-1 is 1499999 bytes, and \-\-max\-size=2g+1 is +2147483649 bytes. +.IP +Note that rsync versions prior to 3.1.0 did not allow \fB\-\-max\-size=0\fP. +.IP +.IP "\fB\-\-min\-size=SIZE\fP" +This tells rsync to avoid transferring any +file that is smaller than the specified SIZE, which can help in not +transferring small, junk files. +See the \fB\-\-max\-size\fP option for a description of SIZE and other information. +.IP +Note that rsync versions prior to 3.1.0 did not allow \fB\-\-min\-size=0\fP. +.IP +.IP "\fB\-B, \-\-block\-size=BLOCKSIZE\fP" +This forces the block size used in +rsync\(cq\&s delta\-transfer algorithm to a fixed value. It is normally selected based on +the size of each file being updated. See the technical report for details. +.IP +.IP "\fB\-e, \-\-rsh=COMMAND\fP" +This option allows you to choose an alternative +remote shell program to use for communication between the local and +remote copies of rsync. Typically, rsync is configured to use ssh by +default, but you may prefer to use rsh on a local network. +.IP +If this option is used with \fB[user@]host::module/path\fP, then the +remote shell \fICOMMAND\fP will be used to run an rsync daemon on the +remote host, and all data will be transmitted through that remote +shell connection, rather than through a direct socket connection to a +running rsync daemon on the remote host. See the section \(dq\&USING +RSYNC\-DAEMON FEATURES VIA A REMOTE\-SHELL CONNECTION\(dq\& above. +.IP +Command\-line arguments are permitted in COMMAND provided that COMMAND is +presented to rsync as a single argument. You must use spaces (not tabs +or other whitespace) to separate the command and args from each other, +and you can use single\- and/or double\-quotes to preserve spaces in an +argument (but not backslashes). Note that doubling a single\-quote +inside a single\-quoted string gives you a single\-quote; likewise for +double\-quotes (though you need to pay attention to which quotes your +shell is parsing and which quotes rsync is parsing). Some examples: +.IP +.RS +\f(CW \-e '\&ssh \-p 2234'\&\fP +.br +\f(CW \-e '\&ssh \-o \(dq\&ProxyCommand nohup ssh firewall nc \-w1 %h %p\(dq\&'\&\fP +.br +.RE + +.IP +(Note that ssh users can alternately customize site\-specific connect +options in their .ssh/config file.) +.IP +You can also choose the remote shell program using the RSYNC_RSH +environment variable, which accepts the same range of values as \fB\-e\fP. +.IP +See also the \fB\-\-blocking\-io\fP option which is affected by this option. +.IP +.IP "\fB\-\-rsync\-path=PROGRAM\fP" +Use this to specify what program is to be run +on the remote machine to start\-up rsync. Often used when rsync is not in +the default remote\-shell\(cq\&s path (e.g. \-\-rsync\-path=/usr/local/bin/rsync). +Note that PROGRAM is run with the help of a shell, so it can be any +program, script, or command sequence you\(cq\&d care to run, so long as it does +not corrupt the standard\-in & standard\-out that rsync is using to +communicate. +.IP +One tricky example is to set a different default directory on the remote +machine for use with the \fB\-\-relative\fP option. For instance: +.IP +.RS +\f(CW rsync \-avR \-\-rsync\-path=\(dq\&cd /a/b && rsync\(dq\& host:c/d /e/\fP +.RE + +.IP +.IP "\fB\-M, \-\-remote\-option=OPTION\fP" +This option is used for more advanced +situations where you want certain effects to be limited to one side of the +transfer only. For instance, if you want to pass \fB\-\-log\-file=FILE\fP and +\fB\-\-fake\-super\fP to the remote system, specify it like this: +.IP +.RS +\f(CW rsync \-av \-M \-\-log\-file=foo \-M\-\-fake\-super src/ dest/\fP +.RE + +.IP +If you want to have an option affect only the local side of a transfer when +it normally affects both sides, send its negation to the remote side. Like +this: +.IP +.RS +\f(CW rsync \-av \-x \-M\-\-no\-x src/ dest/\fP +.RE + +.IP +Be cautious using this, as it is possible to toggle an option that will cause +rsync to have a different idea about what data to expect next over the socket, +and that will make it fail in a cryptic fashion. +.IP +Note that it is best to use a separate \fB\-\-remote\-option\fP for each option you +want to pass. This makes your useage compatible with the \fB\-\-protect\-args\fP +option. If that option is off, any spaces in your remote options will be split +by the remote shell unless you take steps to protect them. +.IP +When performing a local transfer, the \(dq\&local\(dq\& side is the sender and the +\(dq\&remote\(dq\& side is the receiver. +.IP +Note some versions of the popt option\-parsing library have a bug in them that +prevents you from using an adjacent arg with an equal in it next to a short +option letter (e.g. \f(CW\-M\-\-log\-file=/tmp/foo\fP. If this bug affects your +version of popt, you can use the version of popt that is included with rsync. +.IP +.IP "\fB\-C, \-\-cvs\-exclude\fP" +This is a useful shorthand for excluding a +broad range of files that you often don\(cq\&t want to transfer between +systems. It uses a similar algorithm to CVS to determine if +a file should be ignored. +.IP +The exclude list is initialized to exclude the following items (these +initial items are marked as perishable \-\- see the FILTER RULES section): +.IP +.RS +.RS +\f(CWRCS SCCS CVS CVS.adm RCSLOG cvslog.* tags TAGS .make.state +\&.nse_depinfo *~ #* .#* ,* _$* *$ *.old *.bak *.BAK *.orig *.rej .del\-* +*.a *.olb *.o *.obj *.so *.exe *.Z *.elc *.ln core .svn/ .git/ .hg/ .bzr/\fP +.RE +.RE + +.IP +then, files listed in a $HOME/.cvsignore are added to the list and any +files listed in the CVSIGNORE environment variable (all cvsignore names +are delimited by whitespace). +.IP +Finally, any file is ignored if it is in the same directory as a +\&.cvsignore file and matches one of the patterns listed therein. Unlike +rsync\(cq\&s filter/exclude files, these patterns are split on whitespace. +See the \fBcvs\fP(1) manual for more information. +.IP +If you\(cq\&re combining \fB\-C\fP with your own \fB\-\-filter\fP rules, you should +note that these CVS excludes are appended at the end of your own rules, +regardless of where the \fB\-C\fP was placed on the command\-line. This makes them +a lower priority than any rules you specified explicitly. If you want to +control where these CVS excludes get inserted into your filter rules, you +should omit the \fB\-C\fP as a command\-line option and use a combination of +\fB\-\-filter=:C\fP and \fB\-\-filter=\-C\fP (either on your command\-line or by +putting the \(dq\&:C\(dq\& and \(dq\&\-C\(dq\& rules into a filter file with your other rules). +The first option turns on the per\-directory scanning for the .cvsignore +file. The second option does a one\-time import of the CVS excludes +mentioned above. +.IP +.IP "\fB\-f, \-\-filter=RULE\fP" +This option allows you to add rules to selectively +exclude certain files from the list of files to be transferred. This is +most useful in combination with a recursive transfer. +.IP +You may use as many \fB\-\-filter\fP options on the command line as you like +to build up the list of files to exclude. If the filter contains whitespace, +be sure to quote it so that the shell gives the rule to rsync as a single +argument. The text below also mentions that you can use an underscore to +replace the space that separates a rule from its arg. +.IP +See the FILTER RULES section for detailed information on this option. +.IP +.IP "\fB\-F\fP" +The \fB\-F\fP option is a shorthand for adding two \fB\-\-filter\fP rules to +your command. The first time it is used is a shorthand for this rule: +.IP +.RS +\f(CW \-\-filter='\&dir\-merge /.rsync\-filter'\&\fP +.RE + +.IP +This tells rsync to look for per\-directory .rsync\-filter files that have +been sprinkled through the hierarchy and use their rules to filter the +files in the transfer. If \fB\-F\fP is repeated, it is a shorthand for this +rule: +.IP +.RS +\f(CW \-\-filter='\&exclude .rsync\-filter'\&\fP +.RE + +.IP +This filters out the .rsync\-filter files themselves from the transfer. +.IP +See the FILTER RULES section for detailed information on how these options +work. +.IP +.IP "\fB\-\-exclude=PATTERN\fP" +This option is a simplified form of the +\fB\-\-filter\fP option that defaults to an exclude rule and does not allow +the full rule\-parsing syntax of normal filter rules. +.IP +See the FILTER RULES section for detailed information on this option. +.IP +.IP "\fB\-\-exclude\-from=FILE\fP" +This option is related to the \fB\-\-exclude\fP +option, but it specifies a FILE that contains exclude patterns (one per line). +Blank lines in the file and lines starting with \(cq\&;\(cq\& or \(cq\&#\(cq\& are ignored. +If \fIFILE\fP is \fB\-\fP, the list will be read from standard input. +.IP +.IP "\fB\-\-include=PATTERN\fP" +This option is a simplified form of the +\fB\-\-filter\fP option that defaults to an include rule and does not allow +the full rule\-parsing syntax of normal filter rules. +.IP +See the FILTER RULES section for detailed information on this option. +.IP +.IP "\fB\-\-include\-from=FILE\fP" +This option is related to the \fB\-\-include\fP +option, but it specifies a FILE that contains include patterns (one per line). +Blank lines in the file and lines starting with \(cq\&;\(cq\& or \(cq\&#\(cq\& are ignored. +If \fIFILE\fP is \fB\-\fP, the list will be read from standard input. +.IP +.IP "\fB\-\-files\-from=FILE\fP" +Using this option allows you to specify the +exact list of files to transfer (as read from the specified FILE or \fB\-\fP +for standard input). It also tweaks the default behavior of rsync to make +transferring just the specified files and directories easier: +.IP +.RS +.IP o +The \fB\-\-relative\fP (\fB\-R\fP) option is implied, which preserves the path +information that is specified for each item in the file (use +\fB\-\-no\-relative\fP or \fB\-\-no\-R\fP if you want to turn that off). +.IP o +The \fB\-\-dirs\fP (\fB\-d\fP) option is implied, which will create directories +specified in the list on the destination rather than noisily skipping +them (use \fB\-\-no\-dirs\fP or \fB\-\-no\-d\fP if you want to turn that off). +.IP o +The \fB\-\-archive\fP (\fB\-a\fP) option\(cq\&s behavior does not imply \fB\-\-recursive\fP +(\fB\-r\fP), so specify it explicitly, if you want it. +.IP o +These side\-effects change the default state of rsync, so the position +of the \fB\-\-files\-from\fP option on the command\-line has no bearing on how +other options are parsed (e.g. \fB\-a\fP works the same before or after +\fB\-\-files\-from\fP, as does \fB\-\-no\-R\fP and all other options). +.RE + +.IP +The filenames that are read from the FILE are all relative to the +source dir \-\- any leading slashes are removed and no \(dq\&..\(dq\& references are +allowed to go higher than the source dir. For example, take this +command: +.IP +.RS +\f(CW rsync \-a \-\-files\-from=/tmp/foo /usr remote:/backup\fP +.RE + +.IP +If /tmp/foo contains the string \(dq\&bin\(dq\& (or even \(dq\&/bin\(dq\&), the /usr/bin +directory will be created as /backup/bin on the remote host. If it +contains \(dq\&bin/\(dq\& (note the trailing slash), the immediate contents of +the directory would also be sent (without needing to be explicitly +mentioned in the file \-\- this began in version 2.6.4). In both cases, +if the \fB\-r\fP option was enabled, that dir\(cq\&s entire hierarchy would +also be transferred (keep in mind that \fB\-r\fP needs to be specified +explicitly with \fB\-\-files\-from\fP, since it is not implied by \fB\-a\fP). +Also note +that the effect of the (enabled by default) \fB\-\-relative\fP option is to +duplicate only the path info that is read from the file \-\- it does not +force the duplication of the source\-spec path (/usr in this case). +.IP +In addition, the \fB\-\-files\-from\fP file can be read from the remote host +instead of the local host if you specify a \(dq\&host:\(dq\& in front of the file +(the host must match one end of the transfer). As a short\-cut, you can +specify just a prefix of \(dq\&:\(dq\& to mean \(dq\&use the remote end of the +transfer\(dq\&. For example: +.IP +.RS +\f(CW rsync \-a \-\-files\-from=:/path/file\-list src:/ /tmp/copy\fP +.RE + +.IP +This would copy all the files specified in the /path/file\-list file that +was located on the remote \(dq\&src\(dq\& host. +.IP +If the \fB\-\-iconv\fP and \fB\-\-protect\-args\fP options are specified and the +\fB\-\-files\-from\fP filenames are being sent from one host to another, the +filenames will be translated from the sending host\(cq\&s charset to the +receiving host\(cq\&s charset. +.IP +NOTE: sorting the list of files in the \-\-files\-from input helps rsync to be +more efficient, as it will avoid re\-visiting the path elements that are shared +between adjacent entries. If the input is not sorted, some path elements +(implied directories) may end up being scanned multiple times, and rsync will +eventually unduplicate them after they get turned into file\-list elements. +.IP +.IP "\fB\-0, \-\-from0\fP" +This tells rsync that the rules/filenames it reads from a +file are terminated by a null (\(cq\&\e0\(cq\&) character, not a NL, CR, or CR+LF. +This affects \fB\-\-exclude\-from\fP, \fB\-\-include\-from\fP, \fB\-\-files\-from\fP, and any +merged files specified in a \fB\-\-filter\fP rule. +It does not affect \fB\-\-cvs\-exclude\fP (since all names read from a .cvsignore +file are split on whitespace). +.IP +.IP "\fB\-s, \-\-protect\-args\fP" +This option sends all filenames and most options to +the remote rsync without allowing the remote shell to interpret them. This +means that spaces are not split in names, and any non\-wildcard special +characters are not translated (such as ~, $, ;, &, etc.). Wildcards are +expanded on the remote host by rsync (instead of the shell doing it). +.IP +If you use this option with \fB\-\-iconv\fP, the args related to the remote +side will also be translated +from the local to the remote character\-set. The translation happens before +wild\-cards are expanded. See also the \fB\-\-files\-from\fP option. +.IP +You may also control this option via the RSYNC_PROTECT_ARGS environment +variable. If this variable has a non\-zero value, this option will be enabled +by default, otherwise it will be disabled by default. Either state is +overridden by a manually specified positive or negative version of this option +(note that \fB\-\-no\-s\fP and \fB\-\-no\-protect\-args\fP are the negative versions). +Since this option was first introduced in 3.0.0, you\(cq\&ll need to make sure it\(cq\&s +disabled if you ever need to interact with a remote rsync that is older than +that. +.IP +Rsync can also be configured (at build time) to have this option enabled by +default (with is overridden by both the environment and the command\-line). +This option will eventually become a new default setting at some +as\-yet\-undetermined point in the future. +.IP +.IP "\fB\-T, \-\-temp\-dir=DIR\fP" +This option instructs rsync to use DIR as a +scratch directory when creating temporary copies of the files transferred +on the receiving side. The default behavior is to create each temporary +file in the same directory as the associated destination file. +Beginning with rsync 3.1.1, the temp\-file names inside the specified DIR will +not be prefixed with an extra dot (though they will still have a random suffix +added). +.IP +This option is most often used when the receiving disk partition does not +have enough free space to hold a copy of the largest file in the transfer. +In this case (i.e. when the scratch directory is on a different disk +partition), rsync will not be able to rename each received temporary file +over the top of the associated destination file, but instead must copy it +into place. Rsync does this by copying the file over the top of the +destination file, which means that the destination file will contain +truncated data during this copy. If this were not done this way (even if +the destination file were first removed, the data locally copied to a +temporary file in the destination directory, and then renamed into place) +it would be possible for the old file to continue taking up disk space (if +someone had it open), and thus there might not be enough room to fit the +new version on the disk at the same time. +.IP +If you are using this option for reasons other than a shortage of disk +space, you may wish to combine it with the \fB\-\-delay\-updates\fP option, +which will ensure that all copied files get put into subdirectories in the +destination hierarchy, awaiting the end of the transfer. If you don\(cq\&t +have enough room to duplicate all the arriving files on the destination +partition, another way to tell rsync that you aren\(cq\&t overly concerned +about disk space is to use the \fB\-\-partial\-dir\fP option with a relative +path; because this tells rsync that it is OK to stash off a copy of a +single file in a subdir in the destination hierarchy, rsync will use the +partial\-dir as a staging area to bring over the copied file, and then +rename it into place from there. (Specifying a \fB\-\-partial\-dir\fP with +an absolute path does not have this side\-effect.) +.IP +.IP "\fB\-y, \-\-fuzzy\fP" +This option tells rsync that it should look for a +basis file for any destination file that is missing. The current algorithm +looks in the same directory as the destination file for either a file that +has an identical size and modified\-time, or a similarly\-named file. If +found, rsync uses the fuzzy basis file to try to speed up the transfer. +.IP +If the option is repeated, the fuzzy scan will also be done in any matching +alternate destination directories that are specified via \fB\-\-compare\-dest\fP, +\fB\-\-copy\-dest\fP, or \fB\-\-link\-dest\fP. +.IP +Note that the use of the \fB\-\-delete\fP option might get rid of any potential +fuzzy\-match files, so either use \fB\-\-delete\-after\fP or specify some +filename exclusions if you need to prevent this. +.IP +.IP "\fB\-\-compare\-dest=DIR\fP" +This option instructs rsync to use \fIDIR\fP on +the destination machine as an additional hierarchy to compare destination +files against doing transfers (if the files are missing in the destination +directory). If a file is found in \fIDIR\fP that is identical to the +sender\(cq\&s file, the file will NOT be transferred to the destination +directory. This is useful for creating a sparse backup of just files that +have changed from an earlier backup. +This option is typically used to copy into an empty (or newly created) +directory. +.IP +Beginning in version 2.6.4, multiple \fB\-\-compare\-dest\fP directories may be +provided, which will cause rsync to search the list in the order specified +for an exact match. +If a match is found that differs only in attributes, a local copy is made +and the attributes updated. +If a match is not found, a basis file from one of the \fIDIR\fPs will be +selected to try to speed up the transfer. +.IP +If \fIDIR\fP is a relative path, it is relative to the destination directory. +See also \fB\-\-copy\-dest\fP and \fB\-\-link\-dest\fP. +.IP +NOTE: beginning with version 3.1.0, rsync will remove a file from a non\-empty +destination hierarchy if an exact match is found in one of the compare\-dest +hierarchies (making the end result more closely match a fresh copy). +.IP +.IP "\fB\-\-copy\-dest=DIR\fP" +This option behaves like \fB\-\-compare\-dest\fP, but +rsync will also copy unchanged files found in \fIDIR\fP to the destination +directory using a local copy. +This is useful for doing transfers to a new destination while leaving +existing files intact, and then doing a flash\-cutover when all files have +been successfully transferred. +.IP +Multiple \fB\-\-copy\-dest\fP directories may be provided, which will cause +rsync to search the list in the order specified for an unchanged file. +If a match is not found, a basis file from one of the \fIDIR\fPs will be +selected to try to speed up the transfer. +.IP +If \fIDIR\fP is a relative path, it is relative to the destination directory. +See also \fB\-\-compare\-dest\fP and \fB\-\-link\-dest\fP. +.IP +.IP "\fB\-\-link\-dest=DIR\fP" +This option behaves like \fB\-\-copy\-dest\fP, but +unchanged files are hard linked from \fIDIR\fP to the destination directory. +The files must be identical in all preserved attributes (e.g. permissions, +possibly ownership) in order for the files to be linked together. +An example: +.IP +.RS +\f(CW rsync \-av \-\-link\-dest=$PWD/prior_dir host:src_dir/ new_dir/\fP +.RE + +.IP +If file\(cq\&s aren\(cq\&t linking, double\-check their attributes. Also check if some +attributes are getting forced outside of rsync\(cq\&s control, such a mount option +that squishes root to a single user, or mounts a removable drive with generic +ownership (such as OS X\(cq\&s \(dq\&Ignore ownership on this volume\(dq\& option). +.IP +Beginning in version 2.6.4, multiple \fB\-\-link\-dest\fP directories may be +provided, which will cause rsync to search the list in the order specified +for an exact match. +If a match is found that differs only in attributes, a local copy is made +and the attributes updated. +If a match is not found, a basis file from one of the \fIDIR\fPs will be +selected to try to speed up the transfer. +.IP +This option works best when copying into an empty destination hierarchy, as +existing files may get their attributes tweaked, and that can affect alternate +destination files via hard\-links. Also, itemizing of changes can get a bit +muddled. Note that prior to version 3.1.0, an alternate\-directory exact match +would never be found (nor linked into the destination) when a destination file +already exists. +.IP +Note that if you combine this option with \fB\-\-ignore\-times\fP, rsync will not +link any files together because it only links identical files together as a +substitute for transferring the file, never as an additional check after the +file is updated. +.IP +If \fIDIR\fP is a relative path, it is relative to the destination directory. +See also \fB\-\-compare\-dest\fP and \fB\-\-copy\-dest\fP. +.IP +Note that rsync versions prior to 2.6.1 had a bug that could prevent +\fB\-\-link\-dest\fP from working properly for a non\-super\-user when \fB\-o\fP was +specified (or implied by \fB\-a\fP). You can work\-around this bug by avoiding +the \fB\-o\fP option when sending to an old rsync. +.IP +.IP "\fB\-z, \-\-compress\fP" +With this option, rsync compresses the file data +as it is sent to the destination machine, which reduces the amount of data +being transmitted \-\- something that is useful over a slow connection. +.IP +Note that this option typically achieves better compression ratios than can +be achieved by using a compressing remote shell or a compressing transport +because it takes advantage of the implicit information in the matching data +blocks that are not explicitly sent over the connection. This matching\-data +compression comes at a cost of CPU, though, and can be disabled by repeating +the \fB\-z\fP option, but only if both sides are at least version 3.1.1. +.IP +Note that if your version of rsync was compiled with an external zlib (instead +of the zlib that comes packaged with rsync) then it will not support the +old\-style compression, only the new\-style (repeated\-option) compression. In +the future this new\-style compression will likely become the default. +.IP +The client rsync requests new\-style compression on the server via the +\fB\-\-new\-compress\fP option, so if you see that option rejected it means that +the server is not new enough to support \fB\-zz\fP. Rsync also accepts the +\fB\-\-old\-compress\fP option for a future time when new\-style compression +becomes the default. +.IP +See the \fB\-\-skip\-compress\fP option for the default list of file suffixes +that will not be compressed. +.IP +.IP "\fB\-\-compress\-level=NUM\fP" +Explicitly set the compression level to use +(see \fB\-\-compress\fP) instead of letting it default. If NUM is non\-zero, +the \fB\-\-compress\fP option is implied. +.IP +.IP "\fB\-\-skip\-compress=LIST\fP" +Override the list of file suffixes that will +not be compressed. The \fBLIST\fP should be one or more file suffixes +(without the dot) separated by slashes (/). +.IP +You may specify an empty string to indicate that no file should be skipped. +.IP +Simple character\-class matching is supported: each must consist of a list +of letters inside the square brackets (e.g. no special classes, such as +\(dq\&[:alpha:]\(dq\&, are supported, and \(cq\&\-\(cq\& has no special meaning). +.IP +The characters asterisk (*) and question\-mark (?) have no special meaning. +.IP +Here\(cq\&s an example that specifies 6 suffixes to skip (since 1 of the 5 rules +matches 2 suffixes): +.IP +.nf + \-\-skip\-compress=gz/jpg/mp[34]/7z/bz2 +.fi + +.IP +The default list of suffixes that will not be compressed is this (in this +version of rsync): +.IP +\fB7z\fP +\fBace\fP +\fBavi\fP +\fBbz2\fP +\fBdeb\fP +\fBgpg\fP +\fBgz\fP +\fBiso\fP +\fBjpeg\fP +\fBjpg\fP +\fBlz\fP +\fBlzma\fP +\fBlzo\fP +\fBmov\fP +\fBmp3\fP +\fBmp4\fP +\fBogg\fP +\fBpng\fP +\fBrar\fP +\fBrpm\fP +\fBrzip\fP +\fBtbz\fP +\fBtgz\fP +\fBtlz\fP +\fBtxz\fP +\fBxz\fP +\fBz\fP +\fBzip\fP +.IP +This list will be replaced by your \fB\-\-skip\-compress\fP list in all but one +situation: a copy from a daemon rsync will add your skipped suffixes to +its list of non\-compressing files (and its list may be configured to a +different default). +.IP +.IP "\fB\-\-numeric\-ids\fP" +With this option rsync will transfer numeric group +and user IDs rather than using user and group names and mapping them +at both ends. +.IP +By default rsync will use the username and groupname to determine +what ownership to give files. The special uid 0 and the special group +0 are never mapped via user/group names even if the \fB\-\-numeric\-ids\fP +option is not specified. +.IP +If a user or group has no name on the source system or it has no match +on the destination system, then the numeric ID +from the source system is used instead. See also the comments on the +\(dq\&use chroot\(dq\& setting in the rsyncd.conf manpage for information on how +the chroot setting affects rsync\(cq\&s ability to look up the names of the +users and groups and what you can do about it. +.IP +.IP "\fB\-\-usermap=STRING, \-\-groupmap=STRING\fP" +These options allow you to +specify users and groups that should be mapped to other values by the +receiving side. The \fBSTRING\fP is one or more \fBFROM\fP:\fBTO\fP pairs of +values separated by commas. Any matching \fBFROM\fP value from the sender is +replaced with a \fBTO\fP value from the receiver. You may specify usernames +or user IDs for the \fBFROM\fP and \fBTO\fP values, and the \fBFROM\fP value may +also be a wild\-card string, which will be matched against the sender\(cq\&s +names (wild\-cards do NOT match against ID numbers, though see below for +why a \(cq\&*\(cq\& matches everything). You may instead specify a range of ID +numbers via an inclusive range: LOW\-HIGH. For example: +.IP +.nf + \-\-usermap=0\-99:nobody,wayne:admin,*:normal \-\-groupmap=usr:1,1:usr +.fi + +.IP +The first match in the list is the one that is used. You should specify +all your user mappings using a single \fB\-\-usermap\fP option, and/or all +your group mappings using a single \fB\-\-groupmap\fP option. +.IP +Note that the sender\(cq\&s name for the 0 user and group are not transmitted +to the receiver, so you should either match these values using a 0, or use +the names in effect on the receiving side (typically \(dq\&root\(dq\&). All other +\fBFROM\fP names match those in use on the sending side. All \fBTO\fP names +match those in use on the receiving side. +.IP +Any IDs that do not have a name on the sending side are treated as having an +empty name for the purpose of matching. This allows them to be matched via +a \(dq\&*\(dq\& or using an empty name. For instance: +.IP +.nf + \-\-usermap=:nobody \-\-groupmap=*:nobody +.fi + +.IP +When the \fB\-\-numeric\-ids\fP option is used, the sender does not send any +names, so all the IDs are treated as having an empty name. This means that +you will need to specify numeric \fBFROM\fP values if you want to map these +nameless IDs to different values. +.IP +For the \fB\-\-usermap\fP option to have any effect, the \fB\-o\fP (\fB\-\-owner\fP) +option must be used (or implied), and the receiver will need to be running +as a super\-user (see also the \fB\-\-fake\-super\fP option). For the \fB\-\-groupmap\fP +option to have any effect, the \fB\-g\fP (\fB\-\-groups\fP) option must be used +(or implied), and the receiver will need to have permissions to set that +group. +.IP +.IP "\fB\-\-chown=USER:GROUP\fP" +This option forces all files to be owned by USER +with group GROUP. This is a simpler interface than using \fB\-\-usermap\fP and +\fB\-\-groupmap\fP directly, but it is implemented using those options internally, +so you cannot mix them. If either the USER or GROUP is empty, no mapping for +the omitted user/group will occur. If GROUP is empty, the trailing colon may +be omitted, but if USER is empty, a leading colon must be supplied. +.IP +If you specify \(dq\&\-\-chown=foo:bar, this is exactly the same as specifying +\(dq\&\-\-usermap=*:foo \-\-groupmap=*:bar\(dq\&, only easier. +.IP +.IP "\fB\-\-timeout=TIMEOUT\fP" +This option allows you to set a maximum I/O +timeout in seconds. If no data is transferred for the specified time +then rsync will exit. The default is 0, which means no timeout. +.IP +.IP "\fB\-\-contimeout\fP" +This option allows you to set the amount of time +that rsync will wait for its connection to an rsync daemon to succeed. +If the timeout is reached, rsync exits with an error. +.IP +.IP "\fB\-\-address\fP" +By default rsync will bind to the wildcard address when +connecting to an rsync daemon. The \fB\-\-address\fP option allows you to +specify a specific IP address (or hostname) to bind to. See also this +option in the \fB\-\-daemon\fP mode section. +.IP +.IP "\fB\-\-port=PORT\fP" +This specifies an alternate TCP port number to use +rather than the default of 873. This is only needed if you are using the +double\-colon (::) syntax to connect with an rsync daemon (since the URL +syntax has a way to specify the port as a part of the URL). See also this +option in the \fB\-\-daemon\fP mode section. +.IP +.IP "\fB\-\-sockopts\fP" +This option can provide endless fun for people +who like to tune their systems to the utmost degree. You can set all +sorts of socket options which may make transfers faster (or +slower!). Read the man page for the +\f(CWsetsockopt()\fP +system call for +details on some of the options you may be able to set. By default no +special socket options are set. This only affects direct socket +connections to a remote rsync daemon. This option also exists in the +\fB\-\-daemon\fP mode section. +.IP +.IP "\fB\-\-blocking\-io\fP" +This tells rsync to use blocking I/O when launching +a remote shell transport. If the remote shell is either rsh or remsh, +rsync defaults to using +blocking I/O, otherwise it defaults to using non\-blocking I/O. (Note that +ssh prefers non\-blocking I/O.) +.IP +.IP "\fB\-\-outbuf=MODE\fP" +This sets the output buffering mode. The mode can be +None (aka Unbuffered), Line, or Block (aka Full). You may specify as little +as a single letter for the mode, and use upper or lower case. +.IP +The main use of this option is to change Full buffering to Line buffering +when rsync\(cq\&s output is going to a file or pipe. +.IP +.IP "\fB\-i, \-\-itemize\-changes\fP" +Requests a simple itemized list of the +changes that are being made to each file, including attribute changes. +This is exactly the same as specifying \fB\-\-out\-format='\&%i %n%L'\&\fP. +If you repeat the option, unchanged files will also be output, but only +if the receiving rsync is at least version 2.6.7 (you can use \fB\-vv\fP +with older versions of rsync, but that also turns on the output of other +verbose messages). +.IP +The \(dq\&%i\(dq\& escape has a cryptic output that is 11 letters long. The general +format is like the string \fBYXcstpoguax\fP, where \fBY\fP is replaced by the +type of update being done, \fBX\fP is replaced by the file\-type, and the +other letters represent attributes that may be output if they are being +modified. +.IP +The update types that replace the \fBY\fP are as follows: +.IP +.RS +.IP o +A \fB<\fP means that a file is being transferred to the remote host +(sent). +.IP o +A \fB>\fP means that a file is being transferred to the local host +(received). +.IP o +A \fBc\fP means that a local change/creation is occurring for the item +(such as the creation of a directory or the changing of a symlink, etc.). +.IP o +A \fBh\fP means that the item is a hard link to another item (requires +\fB\-\-hard\-links\fP). +.IP o +A \fB.\fP means that the item is not being updated (though it might +have attributes that are being modified). +.IP o +A \fB*\fP means that the rest of the itemized\-output area contains +a message (e.g. \(dq\&deleting\(dq\&). +.RE + +.IP +The file\-types that replace the \fBX\fP are: \fBf\fP for a file, a \fBd\fP for a +directory, an \fBL\fP for a symlink, a \fBD\fP for a device, and a \fBS\fP for a +special file (e.g. named sockets and fifos). +.IP +The other letters in the string above are the actual letters that +will be output if the associated attribute for the item is being updated or +a \(dq\&.\(dq\& for no change. Three exceptions to this are: (1) a newly created +item replaces each letter with a \(dq\&+\(dq\&, (2) an identical item replaces the +dots with spaces, and (3) an unknown attribute replaces each letter with +a \(dq\&?\(dq\& (this can happen when talking to an older rsync). +.IP +The attribute that is associated with each letter is as follows: +.IP +.RS +.IP o +A \fBc\fP means either that a regular file has a different checksum +(requires \fB\-\-checksum\fP) or that a symlink, device, or special file has +a changed value. +Note that if you are sending files to an rsync prior to 3.0.1, this +change flag will be present only for checksum\-differing regular files. +.IP o +A \fBs\fP means the size of a regular file is different and will be updated +by the file transfer. +.IP o +A \fBt\fP means the modification time is different and is being updated +to the sender\(cq\&s value (requires \fB\-\-times\fP). An alternate value of \fBT\fP +means that the modification time will be set to the transfer time, which happens +when a file/symlink/device is updated without \fB\-\-times\fP and when a +symlink is changed and the receiver can\(cq\&t set its time. +(Note: when using an rsync 3.0.0 client, you might see the \fBs\fP flag combined +with \fBt\fP instead of the proper \fBT\fP flag for this time\-setting failure.) +.IP o +A \fBp\fP means the permissions are different and are being updated to +the sender\(cq\&s value (requires \fB\-\-perms\fP). +.IP o +An \fBo\fP means the owner is different and is being updated to the +sender\(cq\&s value (requires \fB\-\-owner\fP and super\-user privileges). +.IP o +A \fBg\fP means the group is different and is being updated to the +sender\(cq\&s value (requires \fB\-\-group\fP and the authority to set the group). +.IP o +The \fBu\fP slot is reserved for future use. +.IP o +The \fBa\fP means that the ACL information changed. +.IP o +The \fBx\fP means that the extended attribute information changed. +.RE + +.IP +One other output is possible: when deleting files, the \(dq\&%i\(dq\& will output +the string \(dq\&*deleting\(dq\& for each item that is being removed (assuming that +you are talking to a recent enough rsync that it logs deletions instead of +outputting them as a verbose message). +.IP +.IP "\fB\-\-out\-format=FORMAT\fP" +This allows you to specify exactly what the +rsync client outputs to the user on a per\-update basis. The format is a +text string containing embedded single\-character escape sequences prefixed +with a percent (%) character. A default format of \(dq\&%n%L\(dq\& is assumed if +either \fB\-\-info=name\fP or \fB\-v\fP is specified (this tells you just the name +of the file and, if the item is a link, where it points). For a full list +of the possible escape characters, see the \(dq\&log format\(dq\& setting in the +rsyncd.conf manpage. +.IP +Specifying the \fB\-\-out\-format\fP option implies the \fB\-\-info=name\fP option, +which will mention each file, dir, etc. that gets updated in a significant +way (a transferred file, a recreated symlink/device, or a touched +directory). In addition, if the itemize\-changes escape (%i) is included in +the string (e.g. if the \fB\-\-itemize\-changes\fP option was used), the logging +of names increases to mention any item that is changed in any way (as long +as the receiving side is at least 2.6.4). See the \fB\-\-itemize\-changes\fP +option for a description of the output of \(dq\&%i\(dq\&. +.IP +Rsync will output the out\-format string prior to a file\(cq\&s transfer unless +one of the transfer\-statistic escapes is requested, in which case the +logging is done at the end of the file\(cq\&s transfer. When this late logging +is in effect and \fB\-\-progress\fP is also specified, rsync will also output +the name of the file being transferred prior to its progress information +(followed, of course, by the out\-format output). +.IP +.IP "\fB\-\-log\-file=FILE\fP" +This option causes rsync to log what it is doing +to a file. This is similar to the logging that a daemon does, but can be +requested for the client side and/or the server side of a non\-daemon +transfer. If specified as a client option, transfer logging will be +enabled with a default format of \(dq\&%i %n%L\(dq\&. See the \fB\-\-log\-file\-format\fP +option if you wish to override this. +.IP +Here\(cq\&s a example command that requests the remote side to log what is +happening: +.IP +.nf + rsync \-av \-\-remote\-option=\-\-log\-file=/tmp/rlog src/ dest/ +.fi + +.IP +This is very useful if you need to debug why a connection is closing +unexpectedly. +.IP +.IP "\fB\-\-log\-file\-format=FORMAT\fP" +This allows you to specify exactly what +per\-update logging is put into the file specified by the \fB\-\-log\-file\fP option +(which must also be specified for this option to have any effect). If you +specify an empty string, updated files will not be mentioned in the log file. +For a list of the possible escape characters, see the \(dq\&log format\(dq\& setting +in the rsyncd.conf manpage. +.IP +The default FORMAT used if \fB\-\-log\-file\fP is specified and this option is not +is \(cq\&%i %n%L\(cq\&. +.IP +.IP "\fB\-\-stats\fP" +This tells rsync to print a verbose set of statistics +on the file transfer, allowing you to tell how effective rsync\(cq\&s delta\-transfer +algorithm is for your data. This option is equivalent to \fB\-\-info=stats2\fP +if combined with 0 or 1 \fB\-v\fP options, or \fB\-\-info=stats3\fP if combined +with 2 or more \fB\-v\fP options. +.IP +The current statistics are as follows: +.RS +.IP o +\fBNumber of files\fP is the count of all \(dq\&files\(dq\& (in the generic +sense), which includes directories, symlinks, etc. The total count will +be followed by a list of counts by filetype (if the total is non\-zero). +For example: \(dq\&(reg: 5, dir: 3, link: 2, dev: 1, special: 1)\(dq\& lists the +totals for regular files, directories, symlinks, devices, and special +files. If any of value is 0, it is completely omitted from the list. +.IP o +\fBNumber of created files\fP is the count of how many \(dq\&files\(dq\& (generic +sense) were created (as opposed to updated). The total count will be +followed by a list of counts by filetype (if the total is non\-zero). +.IP o +\fBNumber of deleted files\fP is the count of how many \(dq\&files\(dq\& (generic +sense) were created (as opposed to updated). The total count will be +followed by a list of counts by filetype (if the total is non\-zero). +Note that this line is only output if deletions are in effect, and only +if protocol 31 is being used (the default for rsync 3.1.x). +.IP o +\fBNumber of regular files transferred\fP is the count of normal files +that were updated via rsync\(cq\&s delta\-transfer algorithm, which does not +include dirs, symlinks, etc. Note that rsync 3.1.0 added the word +\(dq\®ular\(dq\& into this heading. +.IP o +\fBTotal file size\fP is the total sum of all file sizes in the transfer. +This does not count any size for directories or special files, but does +include the size of symlinks. +.IP o +\fBTotal transferred file size\fP is the total sum of all files sizes +for just the transferred files. +.IP o +\fBLiteral data\fP is how much unmatched file\-update data we had to +send to the receiver for it to recreate the updated files. +.IP o +\fBMatched data\fP is how much data the receiver got locally when +recreating the updated files. +.IP o +\fBFile list size\fP is how big the file\-list data was when the sender +sent it to the receiver. This is smaller than the in\-memory size for the +file list due to some compressing of duplicated data when rsync sends the +list. +.IP o +\fBFile list generation time\fP is the number of seconds that the +sender spent creating the file list. This requires a modern rsync on the +sending side for this to be present. +.IP o +\fBFile list transfer time\fP is the number of seconds that the sender +spent sending the file list to the receiver. +.IP o +\fBTotal bytes sent\fP is the count of all the bytes that rsync sent +from the client side to the server side. +.IP o +\fBTotal bytes received\fP is the count of all non\-message bytes that +rsync received by the client side from the server side. \(dq\&Non\-message\(dq\& +bytes means that we don\(cq\&t count the bytes for a verbose message that the +server sent to us, which makes the stats more consistent. +.RE + +.IP +.IP "\fB\-8, \-\-8\-bit\-output\fP" +This tells rsync to leave all high\-bit characters +unescaped in the output instead of trying to test them to see if they\(cq\&re +valid in the current locale and escaping the invalid ones. All control +characters (but never tabs) are always escaped, regardless of this option\(cq\&s +setting. +.IP +The escape idiom that started in 2.6.7 is to output a literal backslash (\e) +and a hash (#), followed by exactly 3 octal digits. For example, a newline +would output as \(dq\&\e#012\(dq\&. A literal backslash that is in a filename is not +escaped unless it is followed by a hash and 3 digits (0\-9). +.IP +.IP "\fB\-h, \-\-human\-readable\fP" +Output numbers in a more human\-readable format. +There are 3 possible levels: (1) output numbers with a separator between each +set of 3 digits (either a comma or a period, depending on if the decimal point +is represented by a period or a comma); (2) output numbers in units of 1000 +(with a character suffix for larger units \-\- see below); (3) output numbers in +units of 1024. +.IP +The default is human\-readable level 1. Each \fB\-h\fP option increases the level +by one. You can take the level down to 0 (to output numbers as pure digits) by +specifing the \fB\-\-no\-human\-readable\fP (\fB\-\-no\-h\fP) option. +.IP +The unit letters that are appended in levels 2 and 3 are: K (kilo), M (mega), +G (giga), or T (tera). For example, a 1234567\-byte file would output as 1.23M +in level\-2 (assuming that a period is your local decimal point). +.IP +Backward compatibility note: versions of rsync prior to 3.1.0 do not support +human\-readable level 1, and they default to level 0. Thus, specifying one or +two \fB\-h\fP options will behave in a comparable manner in old and new versions +as long as you didn\(cq\&t specify a \fB\-\-no\-h\fP option prior to one or more \fB\-h\fP +options. See the \fB\-\-list\-only\fP option for one difference. +.IP +.IP "\fB\-\-partial\fP" +By default, rsync will delete any partially +transferred file if the transfer is interrupted. In some circumstances +it is more desirable to keep partially transferred files. Using the +\fB\-\-partial\fP option tells rsync to keep the partial file which should +make a subsequent transfer of the rest of the file much faster. +.IP +.IP "\fB\-\-partial\-dir=DIR\fP" +A better way to keep partial files than the +\fB\-\-partial\fP option is to specify a \fIDIR\fP that will be used to hold the +partial data (instead of writing it out to the destination file). +On the next transfer, rsync will use a file found in this +dir as data to speed up the resumption of the transfer and then delete it +after it has served its purpose. +.IP +Note that if \fB\-\-whole\-file\fP is specified (or implied), any partial\-dir +file that is found for a file that is being updated will simply be removed +(since +rsync is sending files without using rsync\(cq\&s delta\-transfer algorithm). +.IP +Rsync will create the \fIDIR\fP if it is missing (just the last dir \-\- not +the whole path). This makes it easy to use a relative path (such as +\(dq\&\fB\-\-partial\-dir=.rsync\-partial\fP\(dq\&) to have rsync create the +partial\-directory in the destination file\(cq\&s directory when needed, and then +remove it again when the partial file is deleted. +.IP +If the partial\-dir value is not an absolute path, rsync will add an exclude +rule at the end of all your existing excludes. This will prevent the +sending of any partial\-dir files that may exist on the sending side, and +will also prevent the untimely deletion of partial\-dir items on the +receiving side. An example: the above \fB\-\-partial\-dir\fP option would add +the equivalent of \(dq\&\fB\-f '\&\-p .rsync\-partial/'\&\fP\(dq\& at the end of any other +filter rules. +.IP +If you are supplying your own exclude rules, you may need to add your own +exclude/hide/protect rule for the partial\-dir because (1) the auto\-added +rule may be ineffective at the end of your other rules, or (2) you may wish +to override rsync\(cq\&s exclude choice. For instance, if you want to make +rsync clean\-up any left\-over partial\-dirs that may be lying around, you +should specify \fB\-\-delete\-after\fP and add a \(dq\&risk\(dq\& filter rule, e.g. +\fB\-f '\&R .rsync\-partial/'\&\fP. (Avoid using \fB\-\-delete\-before\fP or +\fB\-\-delete\-during\fP unless you don\(cq\&t need rsync to use any of the +left\-over partial\-dir data during the current run.) +.IP +IMPORTANT: the \fB\-\-partial\-dir\fP should not be writable by other users or it +is a security risk. E.g. AVOID \(dq\&/tmp\(dq\&. +.IP +You can also set the partial\-dir value the RSYNC_PARTIAL_DIR environment +variable. Setting this in the environment does not force \fB\-\-partial\fP to be +enabled, but rather it affects where partial files go when \fB\-\-partial\fP is +specified. For instance, instead of using \fB\-\-partial\-dir=.rsync\-tmp\fP +along with \fB\-\-progress\fP, you could set RSYNC_PARTIAL_DIR=.rsync\-tmp in your +environment and then just use the \fB\-P\fP option to turn on the use of the +\&.rsync\-tmp dir for partial transfers. The only times that the \fB\-\-partial\fP +option does not look for this environment value are (1) when \fB\-\-inplace\fP was +specified (since \fB\-\-inplace\fP conflicts with \fB\-\-partial\-dir\fP), and (2) when +\fB\-\-delay\-updates\fP was specified (see below). +.IP +For the purposes of the daemon\-config\(cq\&s \(dq\&refuse options\(dq\& setting, +\fB\-\-partial\-dir\fP does \fInot\fP imply \fB\-\-partial\fP. This is so that a +refusal of the \fB\-\-partial\fP option can be used to disallow the overwriting +of destination files with a partial transfer, while still allowing the +safer idiom provided by \fB\-\-partial\-dir\fP. +.IP +.IP "\fB\-\-delay\-updates\fP" +This option puts the temporary file from each +updated file into a holding directory until the end of the +transfer, at which time all the files are renamed into place in rapid +succession. This attempts to make the updating of the files a little more +atomic. By default the files are placed into a directory named \(dq\&.~tmp~\(dq\& in +each file\(cq\&s destination directory, but if you\(cq\&ve specified the +\fB\-\-partial\-dir\fP option, that directory will be used instead. See the +comments in the \fB\-\-partial\-dir\fP section for a discussion of how this +\(dq\&.~tmp~\(dq\& dir will be excluded from the transfer, and what you can do if +you want rsync to cleanup old \(dq\&.~tmp~\(dq\& dirs that might be lying around. +Conflicts with \fB\-\-inplace\fP and \fB\-\-append\fP. +.IP +This option uses more memory on the receiving side (one bit per file +transferred) and also requires enough free disk space on the receiving +side to hold an additional copy of all the updated files. Note also that +you should not use an absolute path to \fB\-\-partial\-dir\fP unless (1) +there is no +chance of any of the files in the transfer having the same name (since all +the updated files will be put into a single directory if the path is +absolute) +and (2) there are no mount points in the hierarchy (since the +delayed updates will fail if they can\(cq\&t be renamed into place). +.IP +See also the \(dq\&atomic\-rsync\(dq\& perl script in the \(dq\&support\(dq\& subdir for an +update algorithm that is even more atomic (it uses \fB\-\-link\-dest\fP and a +parallel hierarchy of files). +.IP +.IP "\fB\-m, \-\-prune\-empty\-dirs\fP" +This option tells the receiving rsync to get +rid of empty directories from the file\-list, including nested directories +that have no non\-directory children. This is useful for avoiding the +creation of a bunch of useless directories when the sending rsync is +recursively scanning a hierarchy of files using include/exclude/filter +rules. +.IP +Note that the use of transfer rules, such as the \fB\-\-min\-size\fP option, does +not affect what goes into the file list, and thus does not leave directories +empty, even if none of the files in a directory match the transfer rule. +.IP +Because the file\-list is actually being pruned, this option also affects +what directories get deleted when a delete is active. However, keep in +mind that excluded files and directories can prevent existing items from +being deleted due to an exclude both hiding source files and protecting +destination files. See the perishable filter\-rule option for how to avoid +this. +.IP +You can prevent the pruning of certain empty directories from the file\-list +by using a global \(dq\&protect\(dq\& filter. For instance, this option would ensure +that the directory \(dq\&emptydir\(dq\& was kept in the file\-list: +.IP +.RS +\-\-filter \(cq\&protect emptydir/\(cq\& +.RE + +.IP +Here\(cq\&s an example that copies all .pdf files in a hierarchy, only creating +the necessary destination directories to hold the .pdf files, and ensures +that any superfluous files and directories in the destination are removed +(note the hide filter of non\-directories being used instead of an exclude): +.IP +.RS +rsync \-avm \-\-del \-\-include=\(cq\&*.pdf\(cq\& \-f \(cq\&hide,! */\(cq\& src/ dest +.RE + +.IP +If you didn\(cq\&t want to remove superfluous destination files, the more +time\-honored options of \(dq\&\fB\-\-include='\&*/'\& \-\-exclude='\&*'\&\fP\(dq\& would work fine +in place of the hide\-filter (if that is more natural to you). +.IP +.IP "\fB\-\-progress\fP" +This option tells rsync to print information +showing the progress of the transfer. This gives a bored user +something to watch. +With a modern rsync this is the same as specifying +\fB\-\-info=flist2,name,progress\fP, but any user\-supplied settings for those +info flags takes precedence (e.g. \(dq\&\-\-info=flist0 \-\-progress\(dq\&). +.IP +While rsync is transferring a regular file, it updates a progress line that +looks like this: +.IP +.nf + 782448 63% 110.64kB/s 0:00:04 +.fi + +.IP +In this example, the receiver has reconstructed 782448 bytes or 63% of the +sender\(cq\&s file, which is being reconstructed at a rate of 110.64 kilobytes +per second, and the transfer will finish in 4 seconds if the current rate +is maintained until the end. +.IP +These statistics can be misleading if rsync\(cq\&s delta\-transfer algorithm is +in use. For example, if the sender\(cq\&s file consists of the basis file +followed by additional data, the reported rate will probably drop +dramatically when the receiver gets to the literal data, and the transfer +will probably take much longer to finish than the receiver estimated as it +was finishing the matched part of the file. +.IP +When the file transfer finishes, rsync replaces the progress line with a +summary line that looks like this: +.IP +.nf + 1,238,099 100% 146.38kB/s 0:00:08 (xfr#5, to\-chk=169/396) +.fi + +.IP +In this example, the file was 1,238,099 bytes long in total, the average rate +of transfer for the whole file was 146.38 kilobytes per second over the 8 +seconds that it took to complete, it was the 5th transfer of a regular file +during the current rsync session, and there are 169 more files for the +receiver to check (to see if they are up\-to\-date or not) remaining out of +the 396 total files in the file\-list. +.IP +In an incremental recursion scan, rsync won\(cq\&t know the total number of files +in the file\-list until it reaches the ends of the scan, but since it starts to +transfer files during the scan, it will display a line with the text \(dq\&ir\-chk\(dq\& +(for incremental recursion check) instead of \(dq\&to\-chk\(dq\& until the point that it +knows the full size of the list, at which point it will switch to using +\(dq\&to\-chk\(dq\&. Thus, seeing \(dq\&ir\-chk\(dq\& lets you know that the total count of files +in the file list is still going to increase (and each time it does, the count +of files left to check will increase by the number of the files added to the +list). +.IP +.IP "\fB\-P\fP" +The \fB\-P\fP option is equivalent to \fB\-\-partial\fP \fB\-\-progress\fP. Its +purpose is to make it much easier to specify these two options for a long +transfer that may be interrupted. +.IP +There is also a \fB\-\-info=progress2\fP option that outputs statistics based +on the whole transfer, rather than individual files. Use this flag without +outputting a filename (e.g. avoid \fB\-v\fP or specify \fB\-\-info=name0\fP) if you +want to see how the transfer is doing without scrolling the screen with a +lot of names. (You don\(cq\&t need to specify the \fB\-\-progress\fP option in +order to use \fB\-\-info=progress2\fP.) +.IP +.IP "\fB\-\-password\-file=FILE\fP" +This option allows you to provide a password for +accessing an rsync daemon via a file or via standard input if \fBFILE\fP is +\fB\-\fP. The file should contain just the password on the first line (all other +lines are ignored). Rsync will exit with an error if \fBFILE\fP is world +readable or if a root\-run rsync command finds a non\-root\-owned file. +.IP +This option does not supply a password to a remote shell transport such as +ssh; to learn how to do that, consult the remote shell\(cq\&s documentation. +When accessing an rsync daemon using a remote shell as the transport, this +option only comes into effect after the remote shell finishes its +authentication (i.e. if you have also specified a password in the daemon\(cq\&s +config file). +.IP +.IP "\fB\-\-list\-only\fP" +This option will cause the source files to be listed +instead of transferred. This option is inferred if there is a single source +arg and no destination specified, so its main uses are: (1) to turn a copy +command that includes a +destination arg into a file\-listing command, or (2) to be able to specify +more than one source arg (note: be sure to include the destination). +Caution: keep in mind that a source arg with a wild\-card is expanded by the +shell into multiple args, so it is never safe to try to list such an arg +without using this option. For example: +.IP +.nf + rsync \-av \-\-list\-only foo* dest/ +.fi + +.IP +Starting with rsync 3.1.0, the sizes output by \fB\-\-list\-only\fP are affected +by the \fB\-\-human\-readable\fP option. By default they will contain digit +separators, but higher levels of readability will output the sizes with +unit suffixes. Note also that the column width for the size output has +increased from 11 to 14 characters for all human\-readable levels. Use +\fB\-\-no\-h\fP if you want just digits in the sizes, and the old column width +of 11 characters. +.IP +Compatibility note: when requesting a remote listing of files from an rsync +that is version 2.6.3 or older, you may encounter an error if you ask for a +non\-recursive listing. This is because a file listing implies the \fB\-\-dirs\fP +option w/o \fB\-\-recursive\fP, and older rsyncs don\(cq\&t have that option. To +avoid this problem, either specify the \fB\-\-no\-dirs\fP option (if you don\(cq\&t +need to expand a directory\(cq\&s content), or turn on recursion and exclude +the content of subdirectories: \fB\-r \-\-exclude='\&/*/*'\&\fP. +.IP +.IP "\fB\-\-bwlimit=RATE\fP" +This option allows you to specify the maximum transfer +rate for the data sent over the socket, specified in units per second. The +RATE value can be suffixed with a string to indicate a size multiplier, and may +be a fractional value (e.g. \(dq\&\fB\-\-bwlimit=1.5m\fP\(dq\&). If no suffix is specified, +the value will be assumed to be in units of 1024 bytes (as if \(dq\&K\(dq\& or \(dq\&KiB\(dq\& had +been appended). See the \fB\-\-max\-size\fP option for a description of all the +available suffixes. A value of zero specifies no limit. +.IP +For backward\-compatibility reasons, the rate limit will be rounded to the +nearest KiB unit, so no rate smaller than 1024 bytes per second is possible. +.IP +Rsync writes data over the socket in blocks, and this option both limits the +size of the blocks that rsync writes, and tries to keep the average transfer +rate at the requested limit. Some \(dq\&burstiness\(dq\& may be seen where rsync writes +out a block of data and then sleeps to bring the average rate into compliance. +.IP +Due to the internal buffering of data, the \fB\-\-progress\fP option may not be an +accurate reflection on how fast the data is being sent. This is because some +files can show up as being rapidly sent when the data is quickly buffered, +while other can show up as very slow when the flushing of the output buffer +occurs. This may be fixed in a future version. +.IP +.IP "\fB\-\-write\-batch=FILE\fP" +Record a file that can later be applied to +another identical destination with \fB\-\-read\-batch\fP. See the \(dq\&BATCH MODE\(dq\& +section for details, and also the \fB\-\-only\-write\-batch\fP option. +.IP +.IP "\fB\-\-only\-write\-batch=FILE\fP" +Works like \fB\-\-write\-batch\fP, except that +no updates are made on the destination system when creating the batch. +This lets you transport the changes to the destination system via some +other means and then apply the changes via \fB\-\-read\-batch\fP. +.IP +Note that you can feel free to write the batch directly to some portable +media: if this media fills to capacity before the end of the transfer, you +can just apply that partial transfer to the destination and repeat the +whole process to get the rest of the changes (as long as you don\(cq\&t mind a +partially updated destination system while the multi\-update cycle is +happening). +.IP +Also note that you only save bandwidth when pushing changes to a remote +system because this allows the batched data to be diverted from the sender +into the batch file without having to flow over the wire to the receiver +(when pulling, the sender is remote, and thus can\(cq\&t write the batch). +.IP +.IP "\fB\-\-read\-batch=FILE\fP" +Apply all of the changes stored in FILE, a +file previously generated by \fB\-\-write\-batch\fP. +If \fIFILE\fP is \fB\-\fP, the batch data will be read from standard input. +See the \(dq\&BATCH MODE\(dq\& section for details. +.IP +.IP "\fB\-\-protocol=NUM\fP" +Force an older protocol version to be used. This +is useful for creating a batch file that is compatible with an older +version of rsync. For instance, if rsync 2.6.4 is being used with the +\fB\-\-write\-batch\fP option, but rsync 2.6.3 is what will be used to run the +\fB\-\-read\-batch\fP option, you should use \(dq\&\-\-protocol=28\(dq\& when creating the +batch file to force the older protocol version to be used in the batch +file (assuming you can\(cq\&t upgrade the rsync on the reading system). +.IP +.IP "\fB\-\-iconv=CONVERT_SPEC\fP" +Rsync can convert filenames between character +sets using this option. Using a CONVERT_SPEC of \(dq\&.\(dq\& tells rsync to look up +the default character\-set via the locale setting. Alternately, you can +fully specify what conversion to do by giving a local and a remote charset +separated by a comma in the order \fB\-\-iconv=LOCAL,REMOTE\fP, e.g. +\fB\-\-iconv=utf8,iso88591\fP. This order ensures that the option +will stay the same whether you\(cq\&re pushing or pulling files. +Finally, you can specify either \fB\-\-no\-iconv\fP or a CONVERT_SPEC of \(dq\&\-\(dq\& +to turn off any conversion. +The default setting of this option is site\-specific, and can also be +affected via the RSYNC_ICONV environment variable. +.IP +For a list of what charset names your local iconv library supports, you can +run \(dq\&iconv \-\-list\(dq\&. +.IP +If you specify the \fB\-\-protect\-args\fP option (\fB\-s\fP), rsync will translate +the filenames you specify on the command\-line that are being sent to the +remote host. See also the \fB\-\-files\-from\fP option. +.IP +Note that rsync does not do any conversion of names in filter files +(including include/exclude files). It is up to you to ensure that you\(cq\&re +specifying matching rules that can match on both sides of the transfer. +For instance, you can specify extra include/exclude rules if there are +filename differences on the two sides that need to be accounted for. +.IP +When you pass an \fB\-\-iconv\fP option to an rsync daemon that allows it, the +daemon uses the charset specified in its \(dq\&charset\(dq\& configuration parameter +regardless of the remote charset you actually pass. Thus, you may feel free to +specify just the local charset for a daemon transfer (e.g. \fB\-\-iconv=utf8\fP). +.IP +.IP "\fB\-4, \-\-ipv4\fP or \fB\-6, \-\-ipv6\fP" +Tells rsync to prefer IPv4/IPv6 +when creating sockets. This only affects sockets that rsync has direct +control over, such as the outgoing socket when directly contacting an +rsync daemon. See also these options in the \fB\-\-daemon\fP mode section. +.IP +If rsync was complied without support for IPv6, the \fB\-\-ipv6\fP option +will have no effect. The \fB\-\-version\fP output will tell you if this +is the case. +.IP +.IP "\fB\-\-checksum\-seed=NUM\fP" +Set the checksum seed to the integer NUM. This 4 +byte checksum seed is included in each block and MD4 file checksum calculation +(the more modern MD5 file checksums don\(cq\&t use a seed). By default the checksum +seed is generated by the server and defaults to the current +\f(CWtime()\fP +\&. This +option is used to set a specific checksum seed, which is useful for +applications that want repeatable block checksums, or in the case where the +user wants a more random checksum seed. Setting NUM to 0 causes rsync to use +the default of +\f(CWtime()\fP +for checksum seed. +.IP +.SH "DAEMON OPTIONS" + +.PP +The options allowed when starting an rsync daemon are as follows: +.PP +.IP "\fB\-\-daemon\fP" +This tells rsync that it is to run as a daemon. The +daemon you start running may be accessed using an rsync client using +the \fBhost::module\fP or \fBrsync://host/module/\fP syntax. +.IP +If standard input is a socket then rsync will assume that it is being +run via inetd, otherwise it will detach from the current terminal and +become a background daemon. The daemon will read the config file +(rsyncd.conf) on each connect made by a client and respond to +requests accordingly. See the \fBrsyncd.conf\fP(5) man page for more +details. +.IP +.IP "\fB\-\-address\fP" +By default rsync will bind to the wildcard address when +run as a daemon with the \fB\-\-daemon\fP option. The \fB\-\-address\fP option +allows you to specify a specific IP address (or hostname) to bind to. This +makes virtual hosting possible in conjunction with the \fB\-\-config\fP option. +See also the \(dq\&address\(dq\& global option in the rsyncd.conf manpage. +.IP +.IP "\fB\-\-bwlimit=RATE\fP" +This option allows you to specify the maximum transfer +rate for the data the daemon sends over the socket. The client can still +specify a smaller \fB\-\-bwlimit\fP value, but no larger value will be allowed. +See the client version of this option (above) for some extra details. +.IP +.IP "\fB\-\-config=FILE\fP" +This specifies an alternate config file than +the default. This is only relevant when \fB\-\-daemon\fP is specified. +The default is /etc/rsyncd.conf unless the daemon is running over +a remote shell program and the remote user is not the super\-user; in that case +the default is rsyncd.conf in the current directory (typically $HOME). +.IP +.IP "\fB\-M, \-\-dparam=OVERRIDE\fP" +This option can be used to set a daemon\-config +parameter when starting up rsync in daemon mode. It is equivalent to adding +the parameter at the end of the global settings prior to the first module\(cq\&s +definition. The parameter names can be specified without spaces, if you so +desire. For instance: +.IP +.nf + rsync \-\-daemon \-M pidfile=/path/rsync.pid +.fi + +.IP +.IP "\fB\-\-no\-detach\fP" +When running as a daemon, this option instructs +rsync to not detach itself and become a background process. This +option is required when running as a service on Cygwin, and may also +be useful when rsync is supervised by a program such as +\fBdaemontools\fP or AIX\(cq\&s \fBSystem Resource Controller\fP. +\fB\-\-no\-detach\fP is also recommended when rsync is run under a +debugger. This option has no effect if rsync is run from inetd or +sshd. +.IP +.IP "\fB\-\-port=PORT\fP" +This specifies an alternate TCP port number for the +daemon to listen on rather than the default of 873. See also the \(dq\&port\(dq\& +global option in the rsyncd.conf manpage. +.IP +.IP "\fB\-\-log\-file=FILE\fP" +This option tells the rsync daemon to use the +given log\-file name instead of using the \(dq\&log file\(dq\& setting in the config +file. +.IP +.IP "\fB\-\-log\-file\-format=FORMAT\fP" +This option tells the rsync daemon to use the +given FORMAT string instead of using the \(dq\&log format\(dq\& setting in the config +file. It also enables \(dq\&transfer logging\(dq\& unless the string is empty, in which +case transfer logging is turned off. +.IP +.IP "\fB\-\-sockopts\fP" +This overrides the \fBsocket options\fP setting in the +rsyncd.conf file and has the same syntax. +.IP +.IP "\fB\-v, \-\-verbose\fP" +This option increases the amount of information the +daemon logs during its startup phase. After the client connects, the +daemon\(cq\&s verbosity level will be controlled by the options that the client +used and the \(dq\&max verbosity\(dq\& setting in the module\(cq\&s config section. +.IP +.IP "\fB\-4, \-\-ipv4\fP or \fB\-6, \-\-ipv6\fP" +Tells rsync to prefer IPv4/IPv6 +when creating the incoming sockets that the rsync daemon will use to +listen for connections. One of these options may be required in older +versions of Linux to work around an IPv6 bug in the kernel (if you see +an \(dq\&address already in use\(dq\& error when nothing else is using the port, +try specifying \fB\-\-ipv6\fP or \fB\-\-ipv4\fP when starting the daemon). +.IP +If rsync was complied without support for IPv6, the \fB\-\-ipv6\fP option +will have no effect. The \fB\-\-version\fP output will tell you if this +is the case. +.IP +.IP "\fB\-h, \-\-help\fP" +When specified after \fB\-\-daemon\fP, print a short help +page describing the options available for starting an rsync daemon. + +.PP +.SH "FILTER RULES" + +.PP +The filter rules allow for flexible selection of which files to transfer +(include) and which files to skip (exclude). The rules either directly +specify include/exclude patterns or they specify a way to acquire more +include/exclude patterns (e.g. to read them from a file). +.PP +As the list of files/directories to transfer is built, rsync checks each +name to be transferred against the list of include/exclude patterns in +turn, and the first matching pattern is acted on: if it is an exclude +pattern, then that file is skipped; if it is an include pattern then that +filename is not skipped; if no matching pattern is found, then the +filename is not skipped. +.PP +Rsync builds an ordered list of filter rules as specified on the +command\-line. Filter rules have the following syntax: +.PP +.RS +\f(CWRULE [PATTERN_OR_FILENAME]\fP +.br +\f(CWRULE,MODIFIERS [PATTERN_OR_FILENAME]\fP +.br +.RE + +.PP +You have your choice of using either short or long RULE names, as described +below. If you use a short\-named rule, the \(cq\&,\(cq\& separating the RULE from the +MODIFIERS is optional. The PATTERN or FILENAME that follows (when present) +must come after either a single space or an underscore (_). +Here are the available rule prefixes: +.PP +.RS +\fBexclude, \-\fP specifies an exclude pattern. +.br +\fBinclude, +\fP specifies an include pattern. +.br +\fBmerge, .\fP specifies a merge\-file to read for more rules. +.br +\fBdir\-merge, :\fP specifies a per\-directory merge\-file. +.br +\fBhide, H\fP specifies a pattern for hiding files from the transfer. +.br +\fBshow, S\fP files that match the pattern are not hidden. +.br +\fBprotect, P\fP specifies a pattern for protecting files from deletion. +.br +\fBrisk, R\fP files that match the pattern are not protected. +.br +\fBclear, !\fP clears the current include/exclude list (takes no arg) +.br +.RE + +.PP +When rules are being read from a file, empty lines are ignored, as are +comment lines that start with a \(dq\&#\(dq\&. +.PP +Note that the \fB\-\-include\fP/\fB\-\-exclude\fP command\-line options do not allow the +full range of rule parsing as described above \-\- they only allow the +specification of include/exclude patterns plus a \(dq\&!\(dq\& token to clear the +list (and the normal comment parsing when rules are read from a file). +If a pattern +does not begin with \(dq\&\- \(dq\& (dash, space) or \(dq\&+ \(dq\& (plus, space), then the +rule will be interpreted as if \(dq\&+ \(dq\& (for an include option) or \(dq\&\- \(dq\& (for +an exclude option) were prefixed to the string. A \fB\-\-filter\fP option, on +the other hand, must always contain either a short or long rule name at the +start of the rule. +.PP +Note also that the \fB\-\-filter\fP, \fB\-\-include\fP, and \fB\-\-exclude\fP options take one +rule/pattern each. To add multiple ones, you can repeat the options on +the command\-line, use the merge\-file syntax of the \fB\-\-filter\fP option, or +the \fB\-\-include\-from\fP/\fB\-\-exclude\-from\fP options. +.PP +.SH "INCLUDE/EXCLUDE PATTERN RULES" + +.PP +You can include and exclude files by specifying patterns using the \(dq\&+\(dq\&, +\(dq\&\-\(dq\&, etc. filter rules (as introduced in the FILTER RULES section above). +The include/exclude rules each specify a pattern that is matched against +the names of the files that are going to be transferred. These patterns +can take several forms: +.PP +.IP o +if the pattern starts with a / then it is anchored to a +particular spot in the hierarchy of files, otherwise it is matched +against the end of the pathname. This is similar to a leading ^ in +regular expressions. +Thus \(dq\&/foo\(dq\& would match a name of \(dq\&foo\(dq\& at either the \(dq\&root of the +transfer\(dq\& (for a global rule) or in the merge\-file\(cq\&s directory (for a +per\-directory rule). +An unqualified \(dq\&foo\(dq\& would match a name of \(dq\&foo\(dq\& anywhere in the +tree because the algorithm is applied recursively from the +top down; it behaves as if each path component gets a turn at being the +end of the filename. Even the unanchored \(dq\&sub/foo\(dq\& would match at +any point in the hierarchy where a \(dq\&foo\(dq\& was found within a directory +named \(dq\&sub\(dq\&. See the section on ANCHORING INCLUDE/EXCLUDE PATTERNS for +a full discussion of how to specify a pattern that matches at the root +of the transfer. +.IP o +if the pattern ends with a / then it will only match a +directory, not a regular file, symlink, or device. +.IP o +rsync chooses between doing a simple string match and wildcard +matching by checking if the pattern contains one of these three wildcard +characters: \(cq\&*\(cq\&, \(cq\&?\(cq\&, and \(cq\&[\(cq\& . +.IP o +a \(cq\&*\(cq\& matches any path component, but it stops at slashes. +.IP o +use \(cq\&**\(cq\& to match anything, including slashes. +.IP o +a \(cq\&?\(cq\& matches any character except a slash (/). +.IP o +a \(cq\&[\(cq\& introduces a character class, such as [a\-z] or [[:alpha:]]. +.IP o +in a wildcard pattern, a backslash can be used to escape a wildcard +character, but it is matched literally when no wildcards are present. +This means that there is an extra level of backslash removal when a +pattern contains wildcard characters compared to a pattern that has none. +e.g. if you add a wildcard to \(dq\&foo\ebar\(dq\& (which matches the backslash) you +would need to use \(dq\&foo\e\ebar*\(dq\& to avoid the \(dq\&\eb\(dq\& becoming just \(dq\&b\(dq\&. +.IP o +if the pattern contains a / (not counting a trailing /) or a \(dq\&**\(dq\&, +then it is matched against the full pathname, including any leading +directories. If the pattern doesn\(cq\&t contain a / or a \(dq\&**\(dq\&, then it is +matched only against the final component of the filename. +(Remember that the algorithm is applied recursively so \(dq\&full filename\(dq\& +can actually be any portion of a path from the starting directory on +down.) +.IP o +a trailing \(dq\&dir_name/***\(dq\& will match both the directory (as if +\(dq\&dir_name/\(dq\& had been specified) and everything in the directory +(as if \(dq\&dir_name/**\(dq\& had been specified). This behavior was added in +version 2.6.7. + +.PP +Note that, when using the \fB\-\-recursive\fP (\fB\-r\fP) option (which is implied by +\fB\-a\fP), every subcomponent of every path is visited from the top down, so +include/exclude patterns get applied recursively to each subcomponent\(cq\&s +full name (e.g. to include \(dq\&/foo/bar/baz\(dq\& the subcomponents \(dq\&/foo\(dq\& and +\(dq\&/foo/bar\(dq\& must not be excluded). +The exclude patterns actually short\-circuit the directory traversal stage +when rsync finds the files to send. If a pattern excludes a particular +parent directory, it can render a deeper include pattern ineffectual +because rsync did not descend through that excluded section of the +hierarchy. This is particularly important when using a trailing \(cq\&*\(cq\& rule. +For instance, this won\(cq\&t work: +.PP +.RS +\f(CW+ /some/path/this\-file\-will\-not\-be\-found\fP +.br +\f(CW+ /file\-is\-included\fP +.br +\f(CW\- *\fP +.br +.RE + +.PP +This fails because the parent directory \(dq\&some\(dq\& is excluded by the \(cq\&*\(cq\& +rule, so rsync never visits any of the files in the \(dq\&some\(dq\& or \(dq\&some/path\(dq\& +directories. One solution is to ask for all directories in the hierarchy +to be included by using a single rule: \(dq\&+ */\(dq\& (put it somewhere before the +\(dq\&\- *\(dq\& rule), and perhaps use the \fB\-\-prune\-empty\-dirs\fP option. Another +solution is to add specific include rules for all +the parent dirs that need to be visited. For instance, this set of rules +works fine: +.PP +.RS +\f(CW+ /some/\fP +.br +\f(CW+ /some/path/\fP +.br +\f(CW+ /some/path/this\-file\-is\-found\fP +.br +\f(CW+ /file\-also\-included\fP +.br +\f(CW\- *\fP +.br +.RE + +.PP +Here are some examples of exclude/include matching: +.PP +.IP o +\(dq\&\- *.o\(dq\& would exclude all names matching *.o +.IP o +\(dq\&\- /foo\(dq\& would exclude a file (or directory) named foo in the +transfer\-root directory +.IP o +\(dq\&\- foo/\(dq\& would exclude any directory named foo +.IP o +\(dq\&\- /foo/*/bar\(dq\& would exclude any file named bar which is at two +levels below a directory named foo in the transfer\-root directory +.IP o +\(dq\&\- /foo/**/bar\(dq\& would exclude any file named bar two +or more levels below a directory named foo in the transfer\-root directory +.IP o +The combination of \(dq\&+ */\(dq\&, \(dq\&+ *.c\(dq\&, and \(dq\&\- *\(dq\& would include all +directories and C source files but nothing else (see also the +\fB\-\-prune\-empty\-dirs\fP option) +.IP o +The combination of \(dq\&+ foo/\(dq\&, \(dq\&+ foo/bar.c\(dq\&, and \(dq\&\- *\(dq\& would include +only the foo directory and foo/bar.c (the foo directory must be +explicitly included or it would be excluded by the \(dq\&*\(dq\&) + +.PP +The following modifiers are accepted after a \(dq\&+\(dq\& or \(dq\&\-\(dq\&: +.PP +.IP o +A \fB/\fP specifies that the include/exclude rule should be matched +against the absolute pathname of the current item. For example, +\(dq\&\-/ /etc/passwd\(dq\& would exclude the passwd file any time the transfer +was sending files from the \(dq\&/etc\(dq\& directory, and \(dq\&\-/ subdir/foo\(dq\& +would always exclude \(dq\&foo\(dq\& when it is in a dir named \(dq\&subdir\(dq\&, even +if \(dq\&foo\(dq\& is at the root of the current transfer. +.IP o +A \fB!\fP specifies that the include/exclude should take effect if +the pattern fails to match. For instance, \(dq\&\-! */\(dq\& would exclude all +non\-directories. +.IP o +A \fBC\fP is used to indicate that all the global CVS\-exclude rules +should be inserted as excludes in place of the \(dq\&\-C\(dq\&. No arg should +follow. +.IP o +An \fBs\fP is used to indicate that the rule applies to the sending +side. When a rule affects the sending side, it prevents files from +being transferred. The default is for a rule to affect both sides +unless \fB\-\-delete\-excluded\fP was specified, in which case default rules +become sender\-side only. See also the hide (H) and show (S) rules, +which are an alternate way to specify sending\-side includes/excludes. +.IP o +An \fBr\fP is used to indicate that the rule applies to the receiving +side. When a rule affects the receiving side, it prevents files from +being deleted. See the \fBs\fP modifier for more info. See also the +protect (P) and risk (R) rules, which are an alternate way to +specify receiver\-side includes/excludes. +.IP o +A \fBp\fP indicates that a rule is perishable, meaning that it is +ignored in directories that are being deleted. For instance, the \fB\-C\fP +option\(cq\&s default rules that exclude things like \(dq\&CVS\(dq\& and \(dq\&*.o\(dq\& are +marked as perishable, and will not prevent a directory that was removed +on the source from being deleted on the destination. + +.PP +.SH "MERGE\-FILE FILTER RULES" + +.PP +You can merge whole files into your filter rules by specifying either a +merge (.) or a dir\-merge (:) filter rule (as introduced in the FILTER RULES +section above). +.PP +There are two kinds of merged files \-\- single\-instance (\(cq\&.\(cq\&) and +per\-directory (\(cq\&:\(cq\&). A single\-instance merge file is read one time, and +its rules are incorporated into the filter list in the place of the \(dq\&.\(dq\& +rule. For per\-directory merge files, rsync will scan every directory that +it traverses for the named file, merging its contents when the file exists +into the current list of inherited rules. These per\-directory rule files +must be created on the sending side because it is the sending side that is +being scanned for the available files to transfer. These rule files may +also need to be transferred to the receiving side if you want them to +affect what files don\(cq\&t get deleted (see PER\-DIRECTORY RULES AND DELETE +below). +.PP +Some examples: +.PP +.RS +\f(CWmerge /etc/rsync/default.rules\fP +.br +\f(CW. /etc/rsync/default.rules\fP +.br +\f(CWdir\-merge .per\-dir\-filter\fP +.br +\f(CWdir\-merge,n\- .non\-inherited\-per\-dir\-excludes\fP +.br +\f(CW:n\- .non\-inherited\-per\-dir\-excludes\fP +.br +.RE + +.PP +The following modifiers are accepted after a merge or dir\-merge rule: +.PP +.IP o +A \fB\-\fP specifies that the file should consist of only exclude +patterns, with no other rule\-parsing except for in\-file comments. +.IP o +A \fB+\fP specifies that the file should consist of only include +patterns, with no other rule\-parsing except for in\-file comments. +.IP o +A \fBC\fP is a way to specify that the file should be read in a +CVS\-compatible manner. This turns on \(cq\&n\(cq\&, \(cq\&w\(cq\&, and \(cq\&\-\(cq\&, but also +allows the list\-clearing token (!) to be specified. If no filename is +provided, \(dq\&.cvsignore\(dq\& is assumed. +.IP o +A \fBe\fP will exclude the merge\-file name from the transfer; e.g. +\(dq\&dir\-merge,e .rules\(dq\& is like \(dq\&dir\-merge .rules\(dq\& and \(dq\&\- .rules\(dq\&. +.IP o +An \fBn\fP specifies that the rules are not inherited by subdirectories. +.IP o +A \fBw\fP specifies that the rules are word\-split on whitespace instead +of the normal line\-splitting. This also turns off comments. Note: the +space that separates the prefix from the rule is treated specially, so +\(dq\&\- foo + bar\(dq\& is parsed as two rules (assuming that prefix\-parsing wasn\(cq\&t +also disabled). +.IP o +You may also specify any of the modifiers for the \(dq\&+\(dq\& or \(dq\&\-\(dq\& rules +(above) in order to have the rules that are read in from the file +default to having that modifier set (except for the \fB!\fP modifier, which +would not be useful). For instance, \(dq\&merge,\-/ .excl\(dq\& would +treat the contents of .excl as absolute\-path excludes, +while \(dq\&dir\-merge,s .filt\(dq\& and \(dq\&:sC\(dq\& would each make all their +per\-directory rules apply only on the sending side. If the merge rule +specifies sides to affect (via the \fBs\fP or \fBr\fP modifier or both), +then the rules in the file must not specify sides (via a modifier or +a rule prefix such as \fBhide\fP). + +.PP +Per\-directory rules are inherited in all subdirectories of the directory +where the merge\-file was found unless the \(cq\&n\(cq\& modifier was used. Each +subdirectory\(cq\&s rules are prefixed to the inherited per\-directory rules +from its parents, which gives the newest rules a higher priority than the +inherited rules. The entire set of dir\-merge rules are grouped together in +the spot where the merge\-file was specified, so it is possible to override +dir\-merge rules via a rule that got specified earlier in the list of global +rules. When the list\-clearing rule (\(dq\&!\(dq\&) is read from a per\-directory +file, it only clears the inherited rules for the current merge file. +.PP +Another way to prevent a single rule from a dir\-merge file from being inherited is to +anchor it with a leading slash. Anchored rules in a per\-directory +merge\-file are relative to the merge\-file\(cq\&s directory, so a pattern \(dq\&/foo\(dq\& +would only match the file \(dq\&foo\(dq\& in the directory where the dir\-merge filter +file was found. +.PP +Here\(cq\&s an example filter file which you\(cq\&d specify via \fB\-\-filter=\(dq\&. file\(dq\&:\fP +.PP +.RS +\f(CWmerge /home/user/.global\-filter\fP +.br +\f(CW\- *.gz\fP +.br +\f(CWdir\-merge .rules\fP +.br +\f(CW+ *.[ch]\fP +.br +\f(CW\- *.o\fP +.br +.RE + +.PP +This will merge the contents of the /home/user/.global\-filter file at the +start of the list and also turns the \(dq\&.rules\(dq\& filename into a per\-directory +filter file. All rules read in prior to the start of the directory scan +follow the global anchoring rules (i.e. a leading slash matches at the root +of the transfer). +.PP +If a per\-directory merge\-file is specified with a path that is a parent +directory of the first transfer directory, rsync will scan all the parent +dirs from that starting point to the transfer directory for the indicated +per\-directory file. For instance, here is a common filter (see \fB\-F\fP): +.PP +.RS +\f(CW\-\-filter='\&: /.rsync\-filter'\&\fP +.RE + +.PP +That rule tells rsync to scan for the file .rsync\-filter in all +directories from the root down through the parent directory of the +transfer prior to the start of the normal directory scan of the file in +the directories that are sent as a part of the transfer. (Note: for an +rsync daemon, the root is always the same as the module\(cq\&s \(dq\&path\(dq\&.) +.PP +Some examples of this pre\-scanning for per\-directory files: +.PP +.RS +\f(CWrsync \-avF /src/path/ /dest/dir\fP +.br +\f(CWrsync \-av \-\-filter='\&: ../../.rsync\-filter'\& /src/path/ /dest/dir\fP +.br +\f(CWrsync \-av \-\-filter='\&: .rsync\-filter'\& /src/path/ /dest/dir\fP +.br +.RE + +.PP +The first two commands above will look for \(dq\&.rsync\-filter\(dq\& in \(dq\&/\(dq\& and +\(dq\&/src\(dq\& before the normal scan begins looking for the file in \(dq\&/src/path\(dq\& +and its subdirectories. The last command avoids the parent\-dir scan +and only looks for the \(dq\&.rsync\-filter\(dq\& files in each directory that is +a part of the transfer. +.PP +If you want to include the contents of a \(dq\&.cvsignore\(dq\& in your patterns, +you should use the rule \(dq\&:C\(dq\&, which creates a dir\-merge of the .cvsignore +file, but parsed in a CVS\-compatible manner. You can +use this to affect where the \fB\-\-cvs\-exclude\fP (\fB\-C\fP) option\(cq\&s inclusion of the +per\-directory .cvsignore file gets placed into your rules by putting the +\(dq\&:C\(dq\& wherever you like in your filter rules. Without this, rsync would +add the dir\-merge rule for the .cvsignore file at the end of all your other +rules (giving it a lower priority than your command\-line rules). For +example: +.PP +.RS +\f(CWcat <<EOT | rsync \-avC \-\-filter='\&. \-'\& a/ b\fP +.br +\f(CW+ foo.o\fP +.br +\f(CW:C\fP +.br +\f(CW\- *.old\fP +.br +\f(CWEOT\fP +.br +\f(CWrsync \-avC \-\-include=foo.o \-f :C \-\-exclude='\&*.old'\& a/ b\fP +.br +.RE + +.PP +Both of the above rsync commands are identical. Each one will merge all +the per\-directory .cvsignore rules in the middle of the list rather than +at the end. This allows their dir\-specific rules to supersede the rules +that follow the :C instead of being subservient to all your rules. To +affect the other CVS exclude rules (i.e. the default list of exclusions, +the contents of $HOME/.cvsignore, and the value of $CVSIGNORE) you should +omit the \fB\-C\fP command\-line option and instead insert a \(dq\&\-C\(dq\& rule into +your filter rules; e.g. \(dq\&\fB\-\-filter=\-C\fP\(dq\&. +.PP +.SH "LIST\-CLEARING FILTER RULE" + +.PP +You can clear the current include/exclude list by using the \(dq\&!\(dq\& filter +rule (as introduced in the FILTER RULES section above). The \(dq\¤t\(dq\& +list is either the global list of rules (if the rule is encountered while +parsing the filter options) or a set of per\-directory rules (which are +inherited in their own sub\-list, so a subdirectory can use this to clear +out the parent\(cq\&s rules). +.PP +.SH "ANCHORING INCLUDE/EXCLUDE PATTERNS" + +.PP +As mentioned earlier, global include/exclude patterns are anchored at the +\(dq\&root of the transfer\(dq\& (as opposed to per\-directory patterns, which are +anchored at the merge\-file\(cq\&s directory). If you think of the transfer as +a subtree of names that are being sent from sender to receiver, the +transfer\-root is where the tree starts to be duplicated in the destination +directory. This root governs where patterns that start with a / match. +.PP +Because the matching is relative to the transfer\-root, changing the +trailing slash on a source path or changing your use of the \fB\-\-relative\fP +option affects the path you need to use in your matching (in addition to +changing how much of the file tree is duplicated on the destination +host). The following examples demonstrate this. +.PP +Let\(cq\&s say that we want to match two source files, one with an absolute +path of \(dq\&/home/me/foo/bar\(dq\&, and one with a path of \(dq\&/home/you/bar/baz\(dq\&. +Here is how the various command choices differ for a 2\-source transfer: +.PP +.RS +Example cmd: rsync \-a /home/me /home/you /dest +.br ++/\- pattern: /me/foo/bar +.br ++/\- pattern: /you/bar/baz +.br +Target file: /dest/me/foo/bar +.br +Target file: /dest/you/bar/baz +.br +.RE + +.PP +.RS +Example cmd: rsync \-a /home/me/ /home/you/ /dest +.br ++/\- pattern: /foo/bar (note missing \(dq\&me\(dq\&) +.br ++/\- pattern: /bar/baz (note missing \(dq\&you\(dq\&) +.br +Target file: /dest/foo/bar +.br +Target file: /dest/bar/baz +.br +.RE + +.PP +.RS +Example cmd: rsync \-a \-\-relative /home/me/ /home/you /dest +.br ++/\- pattern: /home/me/foo/bar (note full path) +.br ++/\- pattern: /home/you/bar/baz (ditto) +.br +Target file: /dest/home/me/foo/bar +.br +Target file: /dest/home/you/bar/baz +.br +.RE + +.PP +.RS +Example cmd: cd /home; rsync \-a \-\-relative me/foo you/ /dest +.br ++/\- pattern: /me/foo/bar (starts at specified path) +.br ++/\- pattern: /you/bar/baz (ditto) +.br +Target file: /dest/me/foo/bar +.br +Target file: /dest/you/bar/baz +.br +.RE + +.PP +The easiest way to see what name you should filter is to just +look at the output when using \fB\-\-verbose\fP and put a / in front of the name +(use the \fB\-\-dry\-run\fP option if you\(cq\&re not yet ready to copy any files). +.PP +.SH "PER\-DIRECTORY RULES AND DELETE" + +.PP +Without a delete option, per\-directory rules are only relevant on the +sending side, so you can feel free to exclude the merge files themselves +without affecting the transfer. To make this easy, the \(cq\&e\(cq\& modifier adds +this exclude for you, as seen in these two equivalent commands: +.PP +.RS +\f(CWrsync \-av \-\-filter='\&: .excl'\& \-\-exclude=.excl host:src/dir /dest\fP +.br +\f(CWrsync \-av \-\-filter='\&:e .excl'\& host:src/dir /dest\fP +.br +.RE + +.PP +However, if you want to do a delete on the receiving side AND you want some +files to be excluded from being deleted, you\(cq\&ll need to be sure that the +receiving side knows what files to exclude. The easiest way is to include +the per\-directory merge files in the transfer and use \fB\-\-delete\-after\fP, +because this ensures that the receiving side gets all the same exclude +rules as the sending side before it tries to delete anything: +.PP +.RS +\f(CWrsync \-avF \-\-delete\-after host:src/dir /dest\fP +.RE + +.PP +However, if the merge files are not a part of the transfer, you\(cq\&ll need to +either specify some global exclude rules (i.e. specified on the command +line), or you\(cq\&ll need to maintain your own per\-directory merge files on +the receiving side. An example of the first is this (assume that the +remote .rules files exclude themselves): +.PP +.nf +rsync \-av \-\-filter=\(cq\&: .rules\(cq\& \-\-filter=\(cq\&. /my/extra.rules\(cq\& + \-\-delete host:src/dir /dest +.fi + +.PP +In the above example the extra.rules file can affect both sides of the +transfer, but (on the sending side) the rules are subservient to the rules +merged from the .rules files because they were specified after the +per\-directory merge rule. +.PP +In one final example, the remote side is excluding the .rsync\-filter +files from the transfer, but we want to use our own .rsync\-filter files +to control what gets deleted on the receiving side. To do this we must +specifically exclude the per\-directory merge files (so that they don\(cq\&t get +deleted) and then put rules into the local files to control what else +should not get deleted. Like one of these commands: +.PP +.nf + rsync \-av \-\-filter='\&:e /.rsync\-filter'\& \-\-delete \e + host:src/dir /dest + rsync \-avFF \-\-delete host:src/dir /dest +.fi + +.PP +.SH "BATCH MODE" + +.PP +Batch mode can be used to apply the same set of updates to many +identical systems. Suppose one has a tree which is replicated on a +number of hosts. Now suppose some changes have been made to this +source tree and those changes need to be propagated to the other +hosts. In order to do this using batch mode, rsync is run with the +write\-batch option to apply the changes made to the source tree to one +of the destination trees. The write\-batch option causes the rsync +client to store in a \(dq\&batch file\(dq\& all the information needed to repeat +this operation against other, identical destination trees. +.PP +Generating the batch file once saves having to perform the file +status, checksum, and data block generation more than once when +updating multiple destination trees. Multicast transport protocols can +be used to transfer the batch update files in parallel to many hosts +at once, instead of sending the same data to every host individually. +.PP +To apply the recorded changes to another destination tree, run rsync +with the read\-batch option, specifying the name of the same batch +file, and the destination tree. Rsync updates the destination tree +using the information stored in the batch file. +.PP +For your convenience, a script file is also created when the write\-batch +option is used: it will be named the same as the batch file with \(dq\&.sh\(dq\& +appended. This script file contains a command\-line suitable for updating a +destination tree using the associated batch file. It can be executed using +a Bourne (or Bourne\-like) shell, optionally passing in an alternate +destination tree pathname which is then used instead of the original +destination path. This is useful when the destination tree path on the +current host differs from the one used to create the batch file. +.PP +Examples: +.PP +.RS +\f(CW$ rsync \-\-write\-batch=foo \-a host:/source/dir/ /adest/dir/\fP +.br +\f(CW$ scp foo* remote:\fP +.br +\f(CW$ ssh remote ./foo.sh /bdest/dir/\fP +.br +.RE + +.PP +.RS +\f(CW$ rsync \-\-write\-batch=foo \-a /source/dir/ /adest/dir/\fP +.br +\f(CW$ ssh remote rsync \-\-read\-batch=\- \-a /bdest/dir/ <foo\fP +.br +.RE + +.PP +In these examples, rsync is used to update /adest/dir/ from /source/dir/ +and the information to repeat this operation is stored in \(dq\&foo\(dq\& and +\(dq\&foo.sh\(dq\&. The host \(dq\&remote\(dq\& is then updated with the batched data going +into the directory /bdest/dir. The differences between the two examples +reveals some of the flexibility you have in how you deal with batches: +.PP +.IP o +The first example shows that the initial copy doesn\(cq\&t have to be +local \-\- you can push or pull data to/from a remote host using either the +remote\-shell syntax or rsync daemon syntax, as desired. +.IP o +The first example uses the created \(dq\&foo.sh\(dq\& file to get the right +rsync options when running the read\-batch command on the remote host. +.IP o +The second example reads the batch data via standard input so that +the batch file doesn\(cq\&t need to be copied to the remote machine first. +This example avoids the foo.sh script because it needed to use a modified +\fB\-\-read\-batch\fP option, but you could edit the script file if you wished to +make use of it (just be sure that no other option is trying to use +standard input, such as the \(dq\&\fB\-\-exclude\-from=\-\fP\(dq\& option). + +.PP +Caveats: +.PP +The read\-batch option expects the destination tree that it is updating +to be identical to the destination tree that was used to create the +batch update fileset. When a difference between the destination trees +is encountered the update might be discarded with a warning (if the file +appears to be up\-to\-date already) or the file\-update may be attempted +and then, if the file fails to verify, the update discarded with an +error. This means that it should be safe to re\-run a read\-batch operation +if the command got interrupted. If you wish to force the batched\-update to +always be attempted regardless of the file\(cq\&s size and date, use the \fB\-I\fP +option (when reading the batch). +If an error occurs, the destination tree will probably be in a +partially updated state. In that case, rsync can +be used in its regular (non\-batch) mode of operation to fix up the +destination tree. +.PP +The rsync version used on all destinations must be at least as new as the +one used to generate the batch file. Rsync will die with an error if the +protocol version in the batch file is too new for the batch\-reading rsync +to handle. See also the \fB\-\-protocol\fP option for a way to have the +creating rsync generate a batch file that an older rsync can understand. +(Note that batch files changed format in version 2.6.3, so mixing versions +older than that with newer versions will not work.) +.PP +When reading a batch file, rsync will force the value of certain options +to match the data in the batch file if you didn\(cq\&t set them to the same +as the batch\-writing command. Other options can (and should) be changed. +For instance \fB\-\-write\-batch\fP changes to \fB\-\-read\-batch\fP, +\fB\-\-files\-from\fP is dropped, and the +\fB\-\-filter\fP/\fB\-\-include\fP/\fB\-\-exclude\fP options are not needed unless +one of the \fB\-\-delete\fP options is specified. +.PP +The code that creates the BATCH.sh file transforms any filter/include/exclude +options into a single list that is appended as a \(dq\&here\(dq\& document to the +shell script file. An advanced user can use this to modify the exclude +list if a change in what gets deleted by \fB\-\-delete\fP is desired. A normal +user can ignore this detail and just use the shell script as an easy way +to run the appropriate \fB\-\-read\-batch\fP command for the batched data. +.PP +The original batch mode in rsync was based on \(dq\&rsync+\(dq\&, but the latest +version uses a new implementation. +.PP +.SH "SYMBOLIC LINKS" + +.PP +Three basic behaviors are possible when rsync encounters a symbolic +link in the source directory. +.PP +By default, symbolic links are not transferred at all. A message +\(dq\&skipping non\-regular\(dq\& file is emitted for any symlinks that exist. +.PP +If \fB\-\-links\fP is specified, then symlinks are recreated with the same +target on the destination. Note that \fB\-\-archive\fP implies +\fB\-\-links\fP. +.PP +If \fB\-\-copy\-links\fP is specified, then symlinks are \(dq\&collapsed\(dq\& by +copying their referent, rather than the symlink. +.PP +Rsync can also distinguish \(dq\&safe\(dq\& and \(dq\&unsafe\(dq\& symbolic links. An +example where this might be used is a web site mirror that wishes to +ensure that the rsync module that is copied does not include symbolic links to +\fB/etc/passwd\fP in the public section of the site. Using +\fB\-\-copy\-unsafe\-links\fP will cause any links to be copied as the file +they point to on the destination. Using \fB\-\-safe\-links\fP will cause +unsafe links to be omitted altogether. (Note that you must specify +\fB\-\-links\fP for \fB\-\-safe\-links\fP to have any effect.) +.PP +Symbolic links are considered unsafe if they are absolute symlinks +(start with \fB/\fP), empty, or if they contain enough \(dq\&..\(dq\& +components to ascend from the directory being copied. +.PP +Here\(cq\&s a summary of how the symlink options are interpreted. The list is +in order of precedence, so if your combination of options isn\(cq\&t mentioned, +use the first line that is a complete subset of your options: +.PP +.IP "\fB\-\-copy\-links\fP" +Turn all symlinks into normal files (leaving no +symlinks for any other options to affect). +.PP +.IP "\fB\-\-links \-\-copy\-unsafe\-links\fP" +Turn all unsafe symlinks into files +and duplicate all safe symlinks. +.PP +.IP "\fB\-\-copy\-unsafe\-links\fP" +Turn all unsafe symlinks into files, noisily +skip all safe symlinks. +.PP +.IP "\fB\-\-links \-\-safe\-links\fP" +Duplicate safe symlinks and skip unsafe +ones. +.PP +.IP "\fB\-\-links\fP" +Duplicate all symlinks. +.PP +.SH "DIAGNOSTICS" + +.PP +rsync occasionally produces error messages that may seem a little +cryptic. The one that seems to cause the most confusion is \(dq\&protocol +version mismatch \-\- is your shell clean?\(dq\&. +.PP +This message is usually caused by your startup scripts or remote shell +facility producing unwanted garbage on the stream that rsync is using +for its transport. The way to diagnose this problem is to run your +remote shell like this: +.PP +.RS +\f(CWssh remotehost /bin/true > out.dat\fP +.RE + +.PP +then look at out.dat. If everything is working correctly then out.dat +should be a zero length file. If you are getting the above error from +rsync then you will probably find that out.dat contains some text or +data. Look at the contents and try to work out what is producing +it. The most common cause is incorrectly configured shell startup +scripts (such as .cshrc or .profile) that contain output statements +for non\-interactive logins. +.PP +If you are having trouble debugging filter patterns, then +try specifying the \fB\-vv\fP option.

Non\-string parameters +(such as true/false settings) are expanded when read from the config file. If +a variable does not exist in the environment, or if a sequence of characters is +not a valid reference (such as an un\-paired percent sign), the raw characters +are passed through unchanged. This helps with backward compatibility and +safety (e.g. expanding a non\-existent %VAR% to an empty string in a path could +result in a very unsafe path). The safest way to insert a literal % into a +value is to use %%. +.PP +.IP "\fBmotd file\fP" +This parameter allows you to specify a +\(dq\&message of the day\(dq\& to display to clients on each connect. This +usually contains site information and any legal notices. The default +is no motd file. +This can be overridden by the \fB\-\-dparam=motdfile=FILE\fP +command\-line option when starting the daemon. +.IP +.IP "\fBpid file\fP" +This parameter tells the rsync daemon to write +its process ID to that file. If the file already exists, the rsync +daemon will abort rather than overwrite the file. +This can be overridden by the \fB\-\-dparam=pidfile=FILE\fP +command\-line option when starting the daemon. +.IP +.IP "\fBport\fP" +You can override the default port the daemon will listen on +by specifying this value (defaults to 873). This is ignored if the daemon +is being run by inetd, and is superseded by the \fB\-\-port\fP command\-line option. +.IP +.IP "\fBaddress\fP" +You can override the default IP address the daemon +will listen on by specifying this value. This is ignored if the daemon is +being run by inetd, and is superseded by the \fB\-\-address\fP command\-line option. +.IP +.IP "\fBsocket options\fP" +This parameter can provide endless fun for people +who like to tune their systems to the utmost degree. You can set all +sorts of socket options which may make transfers faster (or +slower!). Read the man page for the +\f(CWsetsockopt()\fP +system call for +details on some of the options you may be able to set. By default no +special socket options are set. These settings can also be specified +via the \fB\-\-sockopts\fP command\-line option. +.IP +.IP "\fBlisten backlog\fP" +You can override the default backlog value when the +daemon listens for connections. It defaults to 5. +.IP +.SH "MODULE PARAMETERS" + +.PP +After the global parameters you should define a number of modules, each +module exports a directory tree as a symbolic name. Modules are +exported by specifying a module name in square brackets [module] +followed by the parameters for that module. +The module name cannot contain a slash or a closing square bracket. If the +name contains whitespace, each internal sequence of whitespace will be +changed into a single space, while leading or trailing whitespace will be +discarded. +Also, the name cannot be \(dq\&global\(dq\& as that exact name indicates that +global parameters follow (see above). +.PP +As with GLOBAL PARAMETERS, you may use references to environment variables in +the values of parameters. See the GLOBAL PARAMETERS section for more details. +.PP +.IP "\fBcomment\fP" +This parameter specifies a description string +that is displayed next to the module name when clients obtain a list +of available modules. The default is no comment. +.IP +.IP "\fBpath\fP" +This parameter specifies the directory in the daemon\(cq\&s +filesystem to make available in this module. You must specify this parameter +for each module in \f(CWrsyncd.conf\fP. +.IP +You may base the path\(cq\&s value off of an environment variable by surrounding +the variable name with percent signs. You can even reference a variable +that is set by rsync when the user connects. +For example, this would use the authorizing user\(cq\&s name in the path: +.IP +.nf + path = /home/%RSYNC_USER_NAME% +.fi + +.IP +It is fine if the path includes internal spaces \-\- they will be retained +verbatim (which means that you shouldn\(cq\&t try to escape them). If your final +directory has a trailing space (and this is somehow not something you wish to +fix), append a trailing slash to the path to avoid losing the trailing +whitespace. +.IP +.IP "\fBuse chroot\fP" +If \(dq\&use chroot\(dq\& is true, the rsync daemon will chroot +to the \(dq\&path\(dq\& before starting the file transfer with the client. This has +the advantage of extra protection against possible implementation security +holes, but it has the disadvantages of requiring super\-user privileges, +of not being able to follow symbolic links that are either absolute or outside +of the new root path, and of complicating the preservation of users and groups +by name (see below). +.IP +As an additional safety feature, you can specify a dot\-dir in the module\(cq\&s +\(dq\&path\(dq\& to indicate the point where the chroot should occur. This allows rsync +to run in a chroot with a non\-\(dq\&/\(dq\& path for the top of the transfer hierarchy. +Doing this guards against unintended library loading (since those absolute +paths will not be inside the transfer hierarchy unless you have used an unwise +pathname), and lets you setup libraries for the chroot that are outside of the +transfer. For example, specifying \(dq\&/var/rsync/./module1\(dq\& will chroot to the +\(dq\&/var/rsync\(dq\& directory and set the inside\-chroot path to \(dq\&/module1\(dq\&. If you +had omitted the dot\-dir, the chroot would have used the whole path, and the +inside\-chroot path would have been \(dq\&/\(dq\&. +.IP +When \(dq\&use chroot\(dq\& is false or the inside\-chroot path is not \(dq\&/\(dq\&, rsync will: +(1) munge symlinks by +default for security reasons (see \(dq\&munge symlinks\(dq\& for a way to turn this +off, but only if you trust your users), (2) substitute leading slashes in +absolute paths with the module\(cq\&s path (so that options such as +\fB\-\-backup\-dir\fP, \fB\-\-compare\-dest\fP, etc. interpret an absolute path as +rooted in the module\(cq\&s \(dq\&path\(dq\& dir), and (3) trim \(dq\&..\(dq\& path elements from +args if rsync believes they would escape the module hierarchy. +The default for \(dq\&use chroot\(dq\& is true, and is the safer choice (especially +if the module is not read\-only). +.IP +When this parameter is enabled, the \(dq\&numeric\-ids\(dq\& option will also default to +being enabled (disabling name lookups). See below for what a chroot needs in +order for name lookups to succeed. +.IP +If you copy library resources into the module\(cq\&s chroot area, you +should protect them through your OS\(cq\&s normal user/group or ACL settings (to +prevent the rsync module\(cq\&s user from being able to change them), and then +hide them from the user\(cq\&s view via \(dq\&exclude\(dq\& (see how in the discussion of +that parameter). At that point it will be safe to enable the mapping of users +and groups by name using this \(dq\&numeric ids\(dq\& daemon parameter. +.IP +Note also that you are free to setup custom user/group information in the +chroot area that is different from your normal system. For example, you +could abbreviate the list of users and groups. +.IP +.IP "\fBnumeric ids\fP" +Enabling this parameter disables the mapping +of users and groups by name for the current daemon module. This prevents +the daemon from trying to load any user/group\-related files or libraries. +This enabling makes the transfer behave as if the client had passed +the \fB\-\-numeric\-ids\fP command\-line option. By default, this parameter is +enabled for chroot modules and disabled for non\-chroot modules. +Also keep in mind that uid/gid preservation requires the module to be +running as root (see \(dq\&uid\(dq\&) or for \(dq\&fake super\(dq\& to be configured. +.IP +A chroot\-enabled module should not have this parameter enabled unless you\(cq\&ve +taken steps to ensure that the module has the necessary resources it needs +to translate names, and that it is not possible for a user to change those +resources. That includes being the code being able to call functions like +\f(CWgetpwuid()\fP +, +\f(CWgetgrgid()\fP +, +\f(CWgetpwname()\fP +, and +\f(CWgetgrnam()\fP +). +You should test what libraries and config files are required for your OS +and get those setup before starting to test name mapping in rsync. +.IP +.IP "\fBmunge symlinks\fP" +This parameter tells rsync to modify +all symlinks in the same way as the (non\-daemon\-affecting) +\fB\-\-munge\-links\fP command\-line option (using a method described below). +This should help protect your files from user trickery when +your daemon module is writable. The default is disabled when \(dq\&use chroot\(dq\& +is on and the inside\-chroot path is \(dq\&/\(dq\&, otherwise it is enabled. +.IP +If you disable this parameter on a daemon that is not read\-only, there +are tricks that a user can play with uploaded symlinks to access +daemon\-excluded items (if your module has any), and, if \(dq\&use chroot\(dq\& +is off, rsync can even be tricked into showing or changing data that +is outside the module\(cq\&s path (as access\-permissions allow). +.IP +The way rsync disables the use of symlinks is to prefix each one with +the string \(dq\&/rsyncd\-munged/\(dq\&. This prevents the links from being used +as long as that directory does not exist. When this parameter is enabled, +rsync will refuse to run if that path is a directory or a symlink to +a directory. When using the \(dq\&munge symlinks\(dq\& parameter in a chroot area +that has an inside\-chroot path of \(dq\&/\(dq\&, you should add \(dq\&/rsyncd\-munged/\(dq\& +to the exclude setting for the module so that +a user can\(cq\&t try to create it. +.IP +Note: rsync makes no attempt to verify that any pre\-existing symlinks in +the module\(cq\&s hierarchy are as safe as you want them to be (unless, of +course, it just copied in the whole hierarchy). If you setup an rsync +daemon on a new area or locally add symlinks, you can manually protect your +symlinks from being abused by prefixing \(dq\&/rsyncd\-munged/\(dq\& to the start of +every symlink\(cq\&s value. There is a perl script in the support directory +of the source code named \(dq\&munge\-symlinks\(dq\& that can be used to add or remove +this prefix from your symlinks. +.IP +When this parameter is disabled on a writable module and \(dq\&use chroot\(dq\& is off +(or the inside\-chroot path is not \(dq\&/\(dq\&), +incoming symlinks will be modified to drop a leading slash and to remove \(dq\&..\(dq\& +path elements that rsync believes will allow a symlink to escape the module\(cq\&s +hierarchy. There are tricky ways to work around this, though, so you had +better trust your users if you choose this combination of parameters. +.IP +.IP "\fBcharset\fP" +This specifies the name of the character set in which the +module\(cq\&s filenames are stored. If the client uses an \fB\-\-iconv\fP option, +the daemon will use the value of the \(dq\&charset\(dq\& parameter regardless of the +character set the client actually passed. This allows the daemon to +support charset conversion in a chroot module without extra files in the +chroot area, and also ensures that name\-translation is done in a consistent +manner. If the \(dq\&charset\(dq\& parameter is not set, the \fB\-\-iconv\fP option is +refused, just as if \(dq\&iconv\(dq\& had been specified via \(dq\&refuse options\(dq\&. +.IP +If you wish to force users to always use \fB\-\-iconv\fP for a particular +module, add \(dq\&no\-iconv\(dq\& to the \(dq\&refuse options\(dq\& parameter. Keep in mind +that this will restrict access to your module to very new rsync clients. +.IP +.IP "\fBmax connections\fP" +This parameter allows you to +specify the maximum number of simultaneous connections you will allow. +Any clients connecting when the maximum has been reached will receive a +message telling them to try later. The default is 0, which means no limit. +A negative value disables the module. +See also the \(dq\&lock file\(dq\& parameter. +.IP +.IP "\fBlog file\fP" +When the \(dq\&log file\(dq\& parameter is set to a non\-empty +string, the rsync daemon will log messages to the indicated file rather +than using syslog. This is particularly useful on systems (such as AIX) +where +\f(CWsyslog()\fP +doesn\(cq\&t work for chrooted programs. The file is +opened before +\f(CWchroot()\fP +is called, allowing it to be placed outside +the transfer. If this value is set on a per\-module basis instead of +globally, the global log will still contain any authorization failures +or config\-file error messages. +.IP +If the daemon fails to open the specified file, it will fall back to +using syslog and output an error about the failure. (Note that the +failure to open the specified log file used to be a fatal error.) +.IP +This setting can be overridden by using the \fB\-\-log\-file=FILE\fP or +\fB\-\-dparam=logfile=FILE\fP command\-line options. The former overrides +all the log\-file parameters of the daemon and all module settings. +The latter sets the daemon\(cq\&s log file and the default for all the +modules, which still allows modules to override the default setting. +.IP +.IP "\fBsyslog facility\fP" +This parameter allows you to +specify the syslog facility name to use when logging messages from the +rsync daemon. You may use any standard syslog facility name which is +defined on your system. Common names are auth, authpriv, cron, daemon, +ftp, kern, lpr, mail, news, security, syslog, user, uucp, local0, +local1, local2, local3, local4, local5, local6 and local7. The default +is daemon. This setting has no effect if the \(dq\&log file\(dq\& setting is a +non\-empty string (either set in the per\-modules settings, or inherited +from the global settings). +.IP +.IP "\fBmax verbosity\fP" +This parameter allows you to control +the maximum amount of verbose information that you\(cq\&ll allow the daemon to +generate (since the information goes into the log file). The default is 1, +which allows the client to request one level of verbosity. +.IP +This also affects the user\(cq\&s ability to request higher levels of \fB\-\-info\fP and +\fB\-\-debug\fP logging. If the max value is 2, then no info and/or debug value +that is higher than what would be set by \fB\-vv\fP will be honored by the daemon +in its logging. To see how high of a verbosity level you need to accept for a +particular info/debug level, refer to \(dq\&rsync \-\-info=help\(dq\& and \(dq\&rsync \-\-debug=help\(dq\&. +For instance, it takes max\-verbosity 4 to be able to output debug TIME2 and FLIST3. +.IP +.IP "\fBlock file\fP" +This parameter specifies the file to use to +support the \(dq\&max connections\(dq\& parameter. The rsync daemon uses record +locking on this file to ensure that the max connections limit is not +exceeded for the modules sharing the lock file. +The default is \f(CW/var/run/rsyncd.lock\fP. +.IP +.IP "\fBread only\fP" +This parameter determines whether clients +will be able to upload files or not. If \(dq\&read only\(dq\& is true then any +attempted uploads will fail. If \(dq\&read only\(dq\& is false then uploads will +be possible if file permissions on the daemon side allow them. The default +is for all modules to be read only. +.IP +Note that \(dq\&auth users\(dq\& can override this setting on a per\-user basis. +.IP +.IP "\fBwrite only\fP" +This parameter determines whether clients +will be able to download files or not. If \(dq\&write only\(dq\& is true then any +attempted downloads will fail. If \(dq\&write only\(dq\& is false then downloads +will be possible if file permissions on the daemon side allow them. The +default is for this parameter to be disabled. +.IP +.IP "\fBlist\fP" +This parameter determines whether this module is +listed when the client asks for a listing of available modules. In addition, +if this is false, the daemon will pretend the module does not exist +when a client denied by \(dq\&hosts allow\(dq\& or \(dq\&hosts deny\(dq\& attempts to access it. +Realize that if \(dq\&reverse lookup\(dq\& is disabled globally but enabled for the +module, the resulting reverse lookup to a potentially client\-controlled DNS +server may still reveal to the client that it hit an existing module. +The default is for modules to be listable. +.IP +.IP "\fBuid\fP" +This parameter specifies the user name or user ID that +file transfers to and from that module should take place as when the daemon +was run as root. In combination with the \(dq\&gid\(dq\& parameter this determines what +file permissions are available. The default when run by a super\-user is to +switch to the system\(cq\&s \(dq\&nobody\(dq\& user. The default for a non\-super\-user is to +not try to change the user. See also the \(dq\&gid\(dq\& parameter. +.IP +The RSYNC_USER_NAME environment variable may be used to request that rsync run +as the authorizing user. For example, if you want a rsync to run as the same +user that was received for the rsync authentication, this setup is useful: +.IP +.nf + uid = %RSYNC_USER_NAME% + gid = * +.fi + +.IP +.IP "\fBgid\fP" +This parameter specifies one or more group names/IDs that will be +used when accessing the module. The first one will be the default group, and +any extra ones be set as supplemental groups. You may also specify a \(dq\&*\(dq\& as +the first gid in the list, which will be replaced by all the normal groups for +the transfer\(cq\&s user (see \(dq\&uid\(dq\&). The default when run by a super\-user is to +switch to your OS\(cq\&s \(dq\&nobody\(dq\& (or perhaps \(dq\&nogroup\(dq\&) group with no other +supplementary groups. The default for a non\-super\-user is to not change any +group attributes (and indeed, your OS may not allow a non\-super\-user to try to +change their group settings). +.IP +.IP "\fBfake super\fP" +Setting \(dq\&fake super = yes\(dq\& for a module causes the +daemon side to behave as if the \fB\-\-fake\-super\fP command\-line option had +been specified. This allows the full attributes of a file to be stored +without having to have the daemon actually running as root. +.IP +.IP "\fBfilter\fP" +The daemon has its own filter chain that determines what files +it will let the client access. This chain is not sent to the client and is +independent of any filters the client may have specified. Files excluded by +the daemon filter chain (\fBdaemon\-excluded\fP files) are treated as non\-existent +if the client tries to pull them, are skipped with an error message if the +client tries to push them (triggering exit code 23), and are never deleted from +the module. You can use daemon filters to prevent clients from downloading or +tampering with private administrative files, such as files you may add to +support uid/gid name translations. +.IP +The daemon filter chain is built from the \(dq\&filter\(dq\&, \(dq\&include from\(dq\&, \(dq\&include\(dq\&, +\(dq\&exclude from\(dq\&, and \(dq\&exclude\(dq\& parameters, in that order of priority. Anchored +patterns are anchored at the root of the module. To prevent access to an +entire subtree, for example, \(dq\&/secret\(dq\&, you \fImust\fP exclude everything in the +subtree; the easiest way to do this is with a triple\-star pattern like +\(dq\&/secret/***\(dq\&. +.IP +The \(dq\&filter\(dq\& parameter takes a space\-separated list of daemon filter rules, +though it is smart enough to know not to split a token at an internal space in +a rule (e.g. \(dq\&\- /foo \- /bar\(dq\& is parsed as two rules). You may specify one or +more merge\-file rules using the normal syntax. Only one \(dq\&filter\(dq\& parameter can +apply to a given module in the config file, so put all the rules you want in a +single parameter. Note that per\-directory merge\-file rules do not provide as +much protection as global rules, but they can be used to make \fB\-\-delete\fP work +better during a client download operation if the per\-dir merge files are +included in the transfer and the client requests that they be used. +.IP +.IP "\fBexclude\fP" +This parameter takes a space\-separated list of daemon +exclude patterns. As with the client \fB\-\-exclude\fP option, patterns can be +qualified with \(dq\&\- \(dq\& or \(dq\&+ \(dq\& to explicitly indicate exclude/include. Only one +\(dq\&exclude\(dq\& parameter can apply to a given module. See the \(dq\&filter\(dq\& parameter +for a description of how excluded files affect the daemon. +.IP +.IP "\fBinclude\fP" +Use an \(dq\&include\(dq\& to override the effects of the \(dq\&exclude\(dq\& +parameter. Only one \(dq\&include\(dq\& parameter can apply to a given module. See the +\(dq\&filter\(dq\& parameter for a description of how excluded files affect the daemon. +.IP +.IP "\fBexclude from\fP" +This parameter specifies the name of a file +on the daemon that contains daemon exclude patterns, one per line. Only one +\(dq\&exclude from\(dq\& parameter can apply to a given module; if you have multiple +exclude\-from files, you can specify them as a merge file in the \(dq\&filter\(dq\& +parameter. See the \(dq\&filter\(dq\& parameter for a description of how excluded files +affect the daemon. +.IP +.IP "\fBinclude from\fP" +Analogue of \(dq\&exclude from\(dq\& for a file of daemon include +patterns. Only one \(dq\&include from\(dq\& parameter can apply to a given module. See +the \(dq\&filter\(dq\& parameter for a description of how excluded files affect the +daemon. +.IP +.IP "\fBincoming chmod\fP" +This parameter allows you to specify a set of +comma\-separated chmod strings that will affect the permissions of all +incoming files (files that are being received by the daemon). These +changes happen after all other permission calculations, and this will +even override destination\-default and/or existing permissions when the +client does not specify \fB\-\-perms\fP. +See the description of the \fB\-\-chmod\fP rsync option and the \fBchmod\fP(1) +manpage for information on the format of this string. +.IP +.IP "\fBoutgoing chmod\fP" +This parameter allows you to specify a set of +comma\-separated chmod strings that will affect the permissions of all +outgoing files (files that are being sent out from the daemon). These +changes happen first, making the sent permissions appear to be different +than those stored in the filesystem itself. For instance, you could +disable group write permissions on the server while having it appear to +be on to the clients. +See the description of the \fB\-\-chmod\fP rsync option and the \fBchmod\fP(1) +manpage for information on the format of this string. +.IP +.IP "\fBauth users\fP" +This parameter specifies a comma and/or space\-separated +list of authorization rules. In its simplest form, you list the usernames +that will be allowed to connect to +this module. The usernames do not need to exist on the local +system. The rules may contain shell wildcard characters that will be matched +against the username provided by the client for authentication. If +\(dq\&auth users\(dq\& is set then the client will be challenged to supply a +username and password to connect to the module. A challenge response +authentication protocol is used for this exchange. The plain text +usernames and passwords are stored in the file specified by the +\(dq\&secrets file\(dq\& parameter. The default is for all users to be able to +connect without a password (this is called \(dq\&anonymous rsync\(dq\&). +.IP +In addition to username matching, you can specify groupname matching via a \(cq\&@\(cq\& +prefix. When using groupname matching, the authenticating username must be a +real user on the system, or it will be assumed to be a member of no groups. +For example, specifying \(dq\&@rsync\(dq\& will match the authenticating user if the +named user is a member of the rsync group. +.IP +Finally, options may be specified after a colon (:). The options allow you to +\(dq\&deny\(dq\& a user or a group, set the access to \(dq\&ro\(dq\& (read\-only), or set the access +to \(dq\&rw\(dq\& (read/write). Setting an auth\-rule\-specific ro/rw setting overrides +the module\(cq\&s \(dq\&read only\(dq\& setting. +.IP +Be sure to put the rules in the order you want them to be matched, because the +checking stops at the first matching user or group, and that is the only auth +that is checked. For example: +.IP +.nf + auth users = joe:deny @guest:deny admin:rw @rsync:ro susan joe sam +.fi + +.IP +In the above rule, user joe will be denied access no matter what. Any user +that is in the group \(dq\&guest\(dq\& is also denied access. The user \(dq\&admin\(dq\& gets +access in read/write mode, but only if the admin user is not in group \(dq\&guest\(dq\& +(because the admin user\-matching rule would never be reached if the user is in +group \(dq\&guest\(dq\&). Any other user who is in group \(dq\&rsync\(dq\& will get read\-only +access. Finally, users susan, joe, and sam get the ro/rw setting of the +module, but only if the user didn\(cq\&t match an earlier group\-matching rule. +.IP +See the description of the secrets file for how you can have per\-user passwords +as well as per\-group passwords. It also explains how a user can authenticate +using their user password or (when applicable) a group password, depending on +what rule is being authenticated. +.IP +See also the section entitled \(dq\&USING RSYNC\-DAEMON FEATURES VIA A REMOTE +SHELL CONNECTION\(dq\& in \fBrsync\fP(1) for information on how handle an +rsyncd.conf\-level username that differs from the remote\-shell\-level +username when using a remote shell to connect to an rsync daemon. +.IP +.IP "\fBsecrets file\fP" +This parameter specifies the name of a file that contains +the username:password and/or @groupname:password pairs used for authenticating +this module. This file is only consulted if the \(dq\&auth users\(dq\& parameter is +specified. The file is line\-based and contains one name:password pair per +line. Any line has a hash (#) as the very first character on the line is +considered a comment and is skipped. The passwords can contain any characters +but be warned that many operating systems limit the length of passwords that +can be typed at the client end, so you may find that passwords longer than 8 +characters don\(cq\&t work. +.IP +The use of group\-specific lines are only relevant when the module is being +authorized using a matching \(dq\&@groupname\(dq\& rule. When that happens, the user +can be authorized via either their \(dq\&username:password\(dq\& line or the +\(dq\&@groupname:password\(dq\& line for the group that triggered the authentication. +.IP +It is up to you what kind of password entries you want to include, either +users, groups, or both. The use of group rules in \(dq\&auth users\(dq\& does not +require that you specify a group password if you do not want to use shared +passwords. +.IP +There is no default for the \(dq\&secrets file\(dq\& parameter, you must choose a name +(such as \f(CW/etc/rsyncd.secrets\fP). The file must normally not be readable +by \(dq\&other\(dq\&; see \(dq\&strict modes\(dq\&. If the file is not found or is rejected, no +logins for a \(dq\&user auth\(dq\& module will be possible. +.IP +.IP "\fBstrict modes\fP" +This parameter determines whether or not +the permissions on the secrets file will be checked. If \(dq\&strict modes\(dq\& is +true, then the secrets file must not be readable by any user ID other +than the one that the rsync daemon is running under. If \(dq\&strict modes\(dq\& is +false, the check is not performed. The default is true. This parameter +was added to accommodate rsync running on the Windows operating system. +.IP +.IP "\fBhosts allow\fP" +This parameter allows you to specify a +list of patterns that are matched against a connecting clients +hostname and IP address. If none of the patterns match then the +connection is rejected. +.IP +Each pattern can be in one of five forms: +.IP +.RS +.IP o +a dotted decimal IPv4 address of the form a.b.c.d, or an IPv6 address +of the form a:b:c::d:e:f. In this case the incoming machine\(cq\&s IP address +must match exactly. +.IP o +an address/mask in the form ipaddr/n where ipaddr is the IP address +and n is the number of one bits in the netmask. All IP addresses which +match the masked IP address will be allowed in. +.IP o +an address/mask in the form ipaddr/maskaddr where ipaddr is the +IP address and maskaddr is the netmask in dotted decimal notation for IPv4, +or similar for IPv6, e.g. ffff:ffff:ffff:ffff:: instead of /64. All IP +addresses which match the masked IP address will be allowed in. +.IP o +a hostname pattern using wildcards. If the hostname of the connecting IP +(as determined by a reverse lookup) matches the wildcarded name (using the +same rules as normal unix filename matching), the client is allowed in. This +only works if \(dq\&reverse lookup\(dq\& is enabled (the default). +.IP o +a hostname. A plain hostname is matched against the reverse DNS of the +connecting IP (if \(dq\&reverse lookup\(dq\& is enabled), and/or the IP of the given +hostname is matched against the connecting IP (if \(dq\&forward lookup\(dq\& is +enabled, as it is by default). Any match will be allowed in. +.RE + +.IP +Note IPv6 link\-local addresses can have a scope in the address specification: +.IP +.RS +\f(CW fe80::1%link1\fP +.br +\f(CW fe80::%link1/64\fP +.br +\f(CW fe80::%link1/ffff:ffff:ffff:ffff::\fP +.br +.RE + +.IP +You can also combine \(dq\&hosts allow\(dq\& with a separate \(dq\&hosts deny\(dq\& +parameter. If both parameters are specified then the \(dq\&hosts allow\(dq\& parameter is +checked first and a match results in the client being able to +connect. The \(dq\&hosts deny\(dq\& parameter is then checked and a match means +that the host is rejected. If the host does not match either the +\(dq\&hosts allow\(dq\& or the \(dq\&hosts deny\(dq\& patterns then it is allowed to +connect. +.IP +The default is no \(dq\&hosts allow\(dq\& parameter, which means all hosts can connect. +.IP +.IP "\fBhosts deny\fP" +This parameter allows you to specify a +list of patterns that are matched against a connecting clients +hostname and IP address. If the pattern matches then the connection is +rejected. See the \(dq\&hosts allow\(dq\& parameter for more information. +.IP +The default is no \(dq\&hosts deny\(dq\& parameter, which means all hosts can connect. +.IP +.IP "\fBreverse lookup\fP" +Controls whether the daemon performs a reverse lookup +on the client\(cq\&s IP address to determine its hostname, which is used for +\(dq\&hosts allow\(dq\&/\(dq\&hosts deny\(dq\& checks and the \(dq\&%h\(dq\& log escape. This is enabled by +default, but you may wish to disable it to save time if you know the lookup will +not return a useful result, in which case the daemon will use the name +\(dq\&UNDETERMINED\(dq\& instead. +.IP +If this parameter is enabled globally (even by default), rsync performs the +lookup as soon as a client connects, so disabling it for a module will not +avoid the lookup. Thus, you probably want to disable it globally and then +enable it for modules that need the information. +.IP +.IP "\fBforward lookup\fP" +Controls whether the daemon performs a forward lookup +on any hostname specified in an hosts allow/deny setting. By default this is +enabled, allowing the use of an explicit hostname that would not be returned +by reverse DNS of the connecting IP. +.IP +.IP "\fBignore errors\fP" +This parameter tells rsyncd to +ignore I/O errors on the daemon when deciding whether to run the delete +phase of the transfer. Normally rsync skips the \fB\-\-delete\fP step if any +I/O errors have occurred in order to prevent disastrous deletion due +to a temporary resource shortage or other I/O error. In some cases this +test is counter productive so you can use this parameter to turn off this +behavior. +.IP +.IP "\fBignore nonreadable\fP" +This tells the rsync daemon to completely +ignore files that are not readable by the user. This is useful for +public archives that may have some non\-readable files among the +directories, and the sysadmin doesn\(cq\&t want those files to be seen at all. +.IP +.IP "\fBtransfer logging\fP" +This parameter enables per\-file +logging of downloads and uploads in a format somewhat similar to that +used by ftp daemons. The daemon always logs the transfer at the end, so +if a transfer is aborted, no mention will be made in the log file. +.IP +If you want to customize the log lines, see the \(dq\&log format\(dq\& parameter. +.IP +.IP "\fBlog format\fP" +This parameter allows you to specify the +format used for logging file transfers when transfer logging is enabled. +The format is a text string containing embedded single\-character escape +sequences prefixed with a percent (%) character. An optional numeric +field width may also be specified between the percent and the escape +letter (e.g. \(dq\&\fB%\-50n %8l %07p\fP\(dq\&). +In addition, one or more apostrophes may be specified prior to a numerical +escape to indicate that the numerical value should be made more human\-readable. +The 3 supported levels are the same as for the \fB\-\-human\-readable\fP +command\-line option, though the default is for human\-readability to be off. +Each added apostrophe increases the level (e.g. \(dq\&\fB%'\&'\&l %'\&b %f\fP\(dq\&). +.IP +The default log format is \(dq\&%o %h [%a] %m (%u) %f %l\(dq\&, and a \(dq\&%t [%p] \(dq\& +is always prefixed when using the \(dq\&log file\(dq\& parameter. +(A perl script that will summarize this default log format is included +in the rsync source code distribution in the \(dq\&support\(dq\& subdirectory: +rsyncstats.) +.IP +The single\-character escapes that are understood are as follows: +.IP +.RS +.IP o +%a the remote IP address (only available for a daemon) +.IP o +%b the number of bytes actually transferred +.IP o +%B the permission bits of the file (e.g. rwxrwxrwt) +.IP o +%c the total size of the block checksums received for the basis file (only when sending) +.IP o +%C the full\-file MD5 checksum if \fB\-\-checksum\fP is enabled or a file was transferred (only for protocol 30 or above). +.IP o +%f the filename (long form on sender; no trailing \(dq\&/\(dq\&) +.IP o +%G the gid of the file (decimal) or \(dq\&DEFAULT\(dq\& +.IP o +%h the remote host name (only available for a daemon) +.IP o +%i an itemized list of what is being updated +.IP o +%l the length of the file in bytes +.IP o +%L the string \(dq\& \-> SYMLINK\(dq\&, \(dq\& => HARDLINK\(dq\&, or \(dq\&\(dq\& (where \fBSYMLINK\fP or \fBHARDLINK\fP is a filename) +.IP o +%m the module name +.IP o +%M the last\-modified time of the file +.IP o +%n the filename (short form; trailing \(dq\&/\(dq\& on dir) +.IP o +%o the operation, which is \(dq\&send\(dq\&, \(dq\&recv\(dq\&, or \(dq\&del.\(dq\& (the latter includes the trailing period) +.IP o +%p the process ID of this rsync session +.IP o +%P the module path +.IP o +%t the current date time +.IP o +%u the authenticated username or an empty string +.IP o +%U the uid of the file (decimal) +.RE + +.IP +For a list of what the characters mean that are output by \(dq\&%i\(dq\&, see the +\fB\-\-itemize\-changes\fP option in the rsync manpage. +.IP +Note that some of the logged output changes when talking with older +rsync versions. For instance, deleted files were only output as verbose +messages prior to rsync 2.6.4. +.IP +.IP "\fBtimeout\fP" +This parameter allows you to override the +clients choice for I/O timeout for this module. Using this parameter you +can ensure that rsync won\(cq\&t wait on a dead client forever. The timeout +is specified in seconds. A value of zero means no timeout and is the +default. A good choice for anonymous rsync daemons may be 600 (giving +a 10 minute timeout). +.IP +.IP "\fBrefuse options\fP" +This parameter allows you to +specify a space\-separated list of rsync command line options that will +be refused by your rsync daemon. +You may specify the full option name, its one\-letter abbreviation, or a +wild\-card string that matches multiple options. +For example, this would refuse \fB\-\-checksum\fP (\fB\-c\fP) and all the various +delete options: +.IP +.RS +\f(CW refuse options = c delete\fP +.RE + +.IP +The reason the above refuses all delete options is that the options imply +\fB\-\-delete\fP, and implied options are refused just like explicit options. +As an additional safety feature, the refusal of \(dq\&delete\(dq\& also refuses +\fBremove\-source\-files\fP when the daemon is the sender; if you want the latter +without the former, instead refuse \(dq\&delete\-*\(dq\& \-\- that refuses all the +delete modes without affecting \fB\-\-remove\-source\-files\fP. +.IP +When an option is refused, the daemon prints an error message and exits. +To prevent all compression when serving files, +you can use \(dq\&dont compress = *\(dq\& (see below) +instead of \(dq\&refuse options = compress\(dq\& to avoid returning an error to a +client that requests compression. +.IP +.IP "\fBdont compress\fP" +This parameter allows you to select +filenames based on wildcard patterns that should not be compressed +when pulling files from the daemon (no analogous parameter exists to +govern the pushing of files to a daemon). +Compression is expensive in terms of CPU usage, so it +is usually good to not try to compress files that won\(cq\&t compress well, +such as already compressed files. +.IP +The \(dq\&dont compress\(dq\& parameter takes a space\-separated list of +case\-insensitive wildcard patterns. Any source filename matching one +of the patterns will not be compressed during transfer. +.IP +See the \fB\-\-skip\-compress\fP parameter in the \fBrsync\fP(1) manpage for the list +of file suffixes that are not compressed by default. Specifying a value +for the \(dq\&dont compress\(dq\& parameter changes the default when the daemon is +the sender. +.IP +.IP "\fBpre\-xfer exec\fP, \fBpost\-xfer exec\fP" +You may specify a command to be run +before and/or after the transfer. If the \fBpre\-xfer exec\fP command fails, the +transfer is aborted before it begins. Any output from the script on stdout (up +to several KB) will be displayed to the user when aborting, but is NOT +displayed if the script returns success. Any output from the script on stderr +goes to the daemon\(cq\&s stderr, which is typically discarded (though see +\-\-no\-detatch option for a way to see the stderr output, which can assist with +debugging). +.IP +The following environment variables will be set, though some are +specific to the pre\-xfer or the post\-xfer environment: +.IP +.RS +.IP o +\fBRSYNC_MODULE_NAME\fP: The name of the module being accessed. +.IP o +\fBRSYNC_MODULE_PATH\fP: The path configured for the module. +.IP o +\fBRSYNC_HOST_ADDR\fP: The accessing host\(cq\&s IP address. +.IP o +\fBRSYNC_HOST_NAME\fP: The accessing host\(cq\&s name. +.IP o +\fBRSYNC_USER_NAME\fP: The accessing user\(cq\&s name (empty if no user). +.IP o +\fBRSYNC_PID\fP: A unique number for this transfer. +.IP o +\fBRSYNC_REQUEST\fP: (pre\-xfer only) The module/path info specified +by the user. Note that the user can specify multiple source files, +so the request can be something like \(dq\&mod/path1 mod/path2\(dq\&, etc. +.IP o +\fBRSYNC_ARG#\fP: (pre\-xfer only) The pre\-request arguments are set +in these numbered values. RSYNC_ARG0 is always \(dq\&rsyncd\(dq\&, followed by +the options that were used in RSYNC_ARG1, and so on. There will be a +value of \(dq\&.\(dq\& indicating that the options are done and the path args +are beginning \-\- these contain similar information to RSYNC_REQUEST, +but with values separated and the module name stripped off. +.IP o +\fBRSYNC_EXIT_STATUS\fP: (post\-xfer only) the server side\(cq\&s exit value. +This will be 0 for a successful run, a positive value for an error that the +server generated, or a \-1 if rsync failed to exit properly. Note that an +error that occurs on the client side does not currently get sent to the +server side, so this is not the final exit status for the whole transfer. +.IP o +\fBRSYNC_RAW_STATUS\fP: (post\-xfer only) the raw exit value from +\f(CWwaitpid()\fP +\&. +.RE + +.IP +Even though the commands can be associated with a particular module, they +are run using the permissions of the user that started the daemon (not the +module\(cq\&s uid/gid setting) without any chroot restrictions. +.IP +.SH "CONFIG DIRECTIVES" + +.PP +There are currently two config directives available that allow a config file to +incorporate the contents of other files: \fB&include\fP and \fB&merge\fP. Both +allow a reference to either a file or a directory. They differ in how +segregated the file\(cq\&s contents are considered to be. +.PP +The \fB&include\fP directive treats each file as more distinct, with each one +inheriting the defaults of the parent file, starting the parameter parsing +as globals/defaults, and leaving the defaults unchanged for the parsing of +the rest of the parent file. +.PP +The \fB&merge\fP directive, on the other hand, treats the file\(cq\&s contents as +if it were simply inserted in place of the directive, and thus it can set +parameters in a module started in another file, can affect the defaults for +other files, etc. +.PP +When an \fB&include\fP or \fB&merge\fP directive refers to a directory, it will read +in all the \fB*.conf\fP or \fB*.inc\fP files (respectively) that are contained inside +that directory (without any +recursive scanning), with the files sorted into alpha order. So, if you have a +directory named \(dq\&rsyncd.d\(dq\& with the files \(dq\&foo.conf\(dq\&, \(dq\&bar.conf\(dq\&, and +\(dq\&baz.conf\(dq\& inside it, this directive: +.PP +.nf + &include /path/rsyncd.d +.fi + +.PP +would be the same as this set of directives: +.PP +.nf + &include /path/rsyncd.d/bar.conf + &include /path/rsyncd.d/baz.conf + &include /path/rsyncd.d/foo.conf +.fi + +.PP +except that it adjusts as files are added and removed from the directory. +.PP +The advantage of the \fB&include\fP directive is that you can define one or more +modules in a separate file without worrying about unintended side\-effects +between the self\-contained module files. +.PP +The advantage of the \fB&merge\fP directive is that you can load config snippets +that can be included into multiple module definitions, and you can also set +global values that will affect connections (such as \fBmotd file\fP), or globals +that will affect other include files. +.PP +For example, this is a useful /etc/rsyncd.conf file: +.PP +.nf + port = 873 + log file = /var/log/rsync.log + pid file = /var/lock/rsync.lock + + &merge /etc/rsyncd.d + &include /etc/rsyncd.d +.fi + +.PP +This would merge any /etc/rsyncd.d/*.inc files (for global values that should +stay in effect), and then include any /etc/rsyncd.d/*.conf files (defining +modules without any global\-value cross\-talk). +.PP +.SH "AUTHENTICATION STRENGTH" + +.PP +The authentication protocol used in rsync is a 128 bit MD4 based +challenge response system. This is fairly weak protection, though (with +at least one brute\-force hash\-finding algorithm publicly available), so +if you want really top\-quality security, then I recommend that you run +rsync over ssh. (Yes, a future version of rsync will switch over to a +stronger hashing method.) +.PP +Also note that the rsync daemon protocol does not currently provide any +encryption of the data that is transferred over the connection. Only +authentication is provided.
