The command is designed to work without user interaction. +<p class="level0">curl offers a busload of useful tricks like proxy support, user authentication, FTP upload, HTTP post, SSL connections, cookies, file transfer resume and more. As you will see below, the number of features will make your head spin! +<p class="level0">curl is powered by libcurl for all transfer-related features. See <span Class="manpage">libcurl (3)</span> for details. <a name="URL"></a><h2 class="nroffsh">URL</h2> +<p class="level0">The URL syntax is protocol-dependent. You'll find a detailed description in RFC 3986. +<p class="level0">You can specify multiple URLs or parts of URLs by writing part sets within braces as in: +<p class="level0"> <a href="http://site">http://site</a>.{one,two,three}.com +<p class="level0">or you can get sequences of alphanumeric series by using [] as in: +<p class="level0"> <a href="ftp://ftp.numericals.com/file">ftp://ftp.numericals.com/file</a>[1-100].txt <a href="ftp://ftp.numericals.com/file">ftp://ftp.numericals.com/file</a>[001-100].txt (with leading zeros) <a href="ftp://ftp.letters.com/file">ftp://ftp.letters.com/file</a>[a-z].txt +<p class="level0">Nested sequences are not supported, but you can use several ones next to each other: +<p class="level0"> <a href="http://any.org/archive">http://any.org/archive</a>[1996-1999]/vol[1-4]/part{a,b,c}.html +<p class="level0">You can specify any amount of URLs on the command line. They will be fetched in a sequential manner in the specified order. +<p class="level0">You can specify a step counter for the ranges to get every Nth number or letter: +<p class="level0"> <a href="http://www.numericals.com/file">http://www.numericals.com/file</a>[1-100:10].txt <a href="http://www.letters.com/file">http://www.letters.com/file</a>[a-z:2].txt +<p class="level0">If you specify URL without protocol:// prefix, curl will attempt to guess what protocol you might want. It will then default to HTTP but try other protocols based on often-used host name prefixes. For example, for host names starting with "ftp." curl will assume you want to speak FTP. +<p class="level0">curl will do its best to use what you pass to it as a URL. It is not trying to validate it as a syntactically correct URL by any means but is instead <span Class="bold">very</span> liberal with what it accepts. +<p class="level0">Curl will attempt to re-use connections for multiple file transfers, so that getting many files from the same server will not do multiple connects / handshakes. This improves speed. Of course this is only done on files specified on a single command line and cannot be used between separate curl invokes. <a name="PROGRESS"></a><h2 class="nroffsh">PROGRESS METER</h2> +<p class="level0">curl normally displays a progress meter during operations, indicating the amount of transferred data, transfer speeds and estimated time left, etc. +<p class="level0">curl displays this data to the terminal by default, so if you invoke curl to do an operation and it is about to write data to the terminal, it <span Class="emphasis">disables</span> the progress meter as otherwise it would mess up the output mixing progress meter and response data. +<p class="level0">If you want a progress meter for HTTP POST or PUT requests, you need to redirect the response output to a file, using shell redirect (>), -o [file] or similar. +<p class="level0">It is not the same case for FTP upload as that operation does not spit out any response data to the terminal. +<p class="level0">If you prefer a progress "bar" instead of the regular meter, <a class="emphasis" href="#-">-#</a> is your friend. <a name="OPTIONS"></a><h2 class="nroffsh">OPTIONS</h2> +<p class="level0">In general, all boolean options are enabled with --option and yet again disabled with --<span Class="bold">no-</span>option. That is, you use the exact same option name but prefix it with "no-". However, in this list we mostly only list and show the --option version of them. (This concept with --no options was added in 7.19.0. Previously most options were toggled on/off on repeated use of the same command line option.) +<p class="level0"><a name="-a--append"></a><span class="nroffip">-a/--append</span> +<p class="level1">(FTP/SFTP) When used in an upload, this will tell curl to append to the target file instead of overwriting it. If the file doesn't exist, it will be created. Note that this flag is ignored by some SSH servers (including OpenSSH). +<p class="level0"><a name="-A--user-agent"></a><span class="nroffip">-A/--user-agent <agent string></span> +<p class="level1">(HTTP) Specify the User-Agent string to send to the HTTP server. Some badly done CGIs fail if this field isn't set to "Mozilla/4.0". To encode blanks in the string, surround the string with single quote marks. This can also be set with the <a class="emphasis" href="#-H--header">-H/--header</a> option of course. +<p class="level1">If this option is set more than once, the last one will be the one that's used. +<p class="level0"><a name="--anyauth"></a><span class="nroffip">--anyauth</span> +<p class="level1">(HTTP) Tells curl to figure out authentication method by itself, and use the most secure one the remote site claims to support. This is done by first doing a request and checking the response-headers, thus possibly inducing an extra network round-trip. This is used instead of setting a specific authentication method, which you can do with <a class="emphasis" href="#--basic">--basic</a>, <a class="emphasis" href="#--digest">--digest</a>, <a class="emphasis" href="#--ntlm">--ntlm</a>, and <a class="emphasis" href="#--negotiate">--negotiate</a>. +<p class="level1">Note that using --anyauth is not recommended if you do uploads from stdin, since it may require data to be sent twice and then the client must be able to rewind. If the need should arise when uploading from stdin, the upload operation will fail. +<p class="level0"><a name="-b--cookie"></a><span class="nroffip">-b/--cookie <name=data></span> +<p class="level1">(HTTP) Pass the data to the HTTP server as a cookie. It is supposedly the data previously received from the server in a "Set-Cookie:" line. The data should be in the format "NAME1=VALUE1; NAME2=VALUE2". +<p class="level1">If no '=' symbol is used in the line, it is treated as a filename to use to read previously stored cookie lines from, which should be used in this session if they match. Using this method also activates the "cookie parser" which will make curl record incoming cookies too, which may be handy if you're using this in combination with the <a class="emphasis" href="#-L--location">-L/--location</a> option. The file format of the file to read cookies from should be plain HTTP headers or the Netscape/Mozilla cookie file format. +<p class="level1"><span Class="bold">NOTE</span> that the file specified with <a class="emphasis" href="#-b--cookie">-b/--cookie</a> is only used as input. No cookies will be stored in the file. To store cookies, use the <a class="emphasis" href="#-c--cookie-jar">-c/--cookie-jar</a> option or you could even save the HTTP headers to a file using <a class="emphasis" href="#-D--dump-header">-D/--dump-header</a>! +<p class="level1">If this option is set more than once, the last one will be the one that's used. +<p class="level0"><a name="-B--use-ascii"></a><span class="nroffip">-B/--use-ascii</span> +<p class="level1">Enable ASCII transfer when using FTP or LDAP. For FTP, this can also be enforced by using an URL that ends with ";type=A". This option causes data sent to stdout to be in text mode for win32 systems. +<p class="level0"><a name="--basic"></a><span class="nroffip">--basic</span> +<p class="level1">(HTTP) Tells curl to use HTTP Basic authentication. This is the default and this option is usually pointless, unless you use it to override a previously set option that sets a different authentication method (such as <a class="emphasis" href="#--ntlm">--ntlm</a>, <a class="emphasis" href="#--digest">--digest</a>, or <a class="emphasis" href="#--negotiate">--negotiate</a>). +<p class="level0"><a name="--ciphers"></a><span class="nroffip">--ciphers <list of ciphers></span> +<p class="level1">(SSL) Specifies which ciphers to use in the connection. The list of ciphers must specify valid ciphers. Read up on SSL cipher list details on this URL: <span Class="emphasis"><a href="http://www.openssl.org/docs/apps/ciphers.html">http://www.openssl.org/docs/apps/ciphers.html</a></span> +<p class="level1">NSS ciphers are done differently than OpenSSL and GnuTLS. The full list of NSS ciphers is in the NSSCipherSuite entry at this URL: <span Class="emphasis"><a href="http://directory.fedora.redhat.com/docs/mod_nss.html">http://directory.fedora.redhat.com/docs/mod_nss.html</a>#Directives</span> +<p class="level1">If this option is used several times, the last one will override the others. +<p class="level0"><a name="--compressed"></a><span class="nroffip">--compressed</span> +<p class="level1">(HTTP) Request a compressed response using one of the algorithms libcurl supports, and return the uncompressed document. If this option is used and the server sends an unsupported encoding, curl will report an error. +<p class="level0"><a name="--connect-timeout"></a><span class="nroffip">--connect-timeout <seconds></span> +<p class="level1">Maximum time in seconds that you allow the connection to the server to take. This only limits the connection phase, once curl has connected this option is of no more use. See also the <a class="emphasis" href="#-m--max-time">-m/--max-time</a> option. +<p class="level1">If this option is used several times, the last one will be used. +<p class="level0"><a name="-c--cookie-jar"></a><span class="nroffip">-c/--cookie-jar <file name></span> +<p class="level1">Specify to which file you want curl to write all cookies after a completed operation. Curl writes all cookies previously read from a specified file as well as all cookies received from remote server(s). If no cookies are known, no file will be written. The file will be written using the Netscape cookie file format. If you set the file name to a single dash, "-", the cookies will be written to stdout. +<p class="level1"><span Class="bold">NOTE</span> If the cookie jar can't be created or written to, the whole curl operation won't fail or even report an error clearly. Using -v will get a warning displayed, but that is the only visible feedback you get about this possibly lethal situation. +<p class="level1">If this option is used several times, the last specified file name will be used. +<p class="level0"><a name="-C--continue-at"></a><span class="nroffip">-C/--continue-at <offset></span> +<p class="level1">Continue/Resume a previous file transfer at the given offset. The given offset is the exact number of bytes that will be skipped, counting from the beginning of the source file before it is transferred to the destination. If used with uploads, the FTP server command SIZE will not be used by curl. +<p class="level1">Use "-C -" to tell curl to automatically find out where/how to resume the transfer. It then uses the given output/input files to figure that out. +<p class="level1">If this option is used several times, the last one will be used. +<p class="level0"><a name="--create-dirs"></a><span class="nroffip">--create-dirs</span> +<p class="level1">When used in conjunction with the -o option, curl will create the necessary local directory hierarchy as needed. This option creates the dirs mentioned with the -o option, nothing else. If the -o file name uses no dir or if the dirs it mentions already exist, no dir will be created. +<p class="level1">To create remote directories when using FTP or SFTP, try <a class="emphasis" href="#--ftp-create-dirs">--ftp-create-dirs</a>. +<p class="level0"><a name="--crlf"></a><span class="nroffip">--crlf</span> +<p class="level1">(FTP) Convert LF to CRLF in upload. Useful for MVS (OS/390). +<p class="level0"><a name="--crlfile"></a><span class="nroffip">--crlfile <file></span> +<p class="level1">(HTTPS/FTPS) Provide a file using PEM format with a Certificate Revocation List that may specify peer certificates that are to be considered revoked. +<p class="level1">If this option is used several times, the last one will be used. +<p class="level1">(Added in 7.19.7) +<p class="level0"><a name="-d--data"></a><span class="nroffip">-d/--data <data></span> +<p class="level1">(HTTP) Sends the specified data in a POST request to the HTTP server, in the same way that a browser does when a user has filled in an HTML form and presses the submit button. This will cause curl to pass the data to the server using the content-type application/x-www-form-urlencoded. Compare to <a class="emphasis" href="#-F--form">-F/--form</a>. +<p class="level1"><a class="emphasis" href="#-d--data">-d/--data</a> is the same as <span Class="emphasis">--data-ascii</span>. To post data purely binary, you should instead use the <a class="emphasis" href="#--data-binary">--data-binary</a> option. To URL-encode the value of a form field you may use <a class="emphasis" href="#--data-urlencode">--data-urlencode</a>. +<p class="level1">If any of these options is used more than once on the same command line, the data pieces specified will be merged together with a separating &-symbol. Thus, using '-d name=daniel -d skill=lousy' would generate a post chunk that looks like 'name=daniel&skill=lousy'. +<p class="level1">If you start the data with the letter @, the rest should be a file name to read the data from, or - if you want curl to read the data from stdin. The contents of the file must already be URL-encoded. Multiple files can also be specified. Posting data from a file named 'foobar' would thus be done with <span Class="emphasis">--data @foobar</span>. +<p class="level0"><a name="--data-binary"></a><span class="nroffip">--data-binary <data></span> +<p class="level1">(HTTP) This posts data exactly as specified with no extra processing whatsoever. +<p class="level1">If you start the data with the letter @, the rest should be a filename. Data is posted in a similar manner as <span Class="emphasis">--data-ascii</span> does, except that newlines are preserved and conversions are never done. +<p class="level1">If this option is used several times, the ones following the first will append data as described in <a class="emphasis" href="#-d--data">-d/--data</a>. +<p class="level0"><a name="--data-urlencode"></a><span class="nroffip">--data-urlencode <data></span> +<p class="level1">(HTTP) This posts data, similar to the other --data options with the exception that this performs URL-encoding. (Added in 7.18.0) +<p class="level1">To be CGI-compliant, the <data> part should begin with a <span Class="emphasis">name</span> followed by a separator and a content specification. The <data> part can be passed to curl using one of the following syntaxes: +<p class="level2"> +<p class="level1"><a name="content"></a><span class="nroffip">content</span> +<p class="level2">This will make curl URL-encode the content and pass that on. Just be careful so that the content doesn't contain any = or @ symbols, as that will then make the syntax match one of the other cases below! +<p class="level1"><a name="content"></a><span class="nroffip">=content</span> +<p class="level2">This will make curl URL-encode the content and pass that on. The preceding = symbol is not included in the data. +<p class="level1"><a name="namecontent"></a><span class="nroffip">name=content</span> +<p class="level2">This will make curl URL-encode the content part and pass that on. Note that the name part is expected to be URL-encoded already. +<p class="level1"><a name="filename"></a><span class="nroffip">@filename</span> +<p class="level2">This will make curl load data from the given file (including any newlines), URL-encode that data and pass it on in the POST. +<p class="level1"><a name="namefilename"></a><span class="nroffip">name@filename</span> +<p class="level2">This will make curl load data from the given file (including any newlines), URL-encode that data and pass it on in the POST. The name part gets an equal sign appended, resulting in <span Class="emphasis">name=urlencoded-file-content</span>. Note that the name is expected to be URL-encoded already. +<p class="level1"> +<p class="level0"><a name="--digest"></a><span class="nroffip">--digest</span> +<p class="level1">(HTTP) Enables HTTP Digest authentication. This is a authentication that prevents the password from being sent over the wire in clear text. Use this in combination with the normal <a class="emphasis" href="#-u--user">-u/--user</a> option to set user name and password. See also <a class="emphasis" href="#--ntlm">--ntlm</a>, <a class="emphasis" href="#--negotiate">--negotiate</a> and <a class="emphasis" href="#--anyauth">--anyauth</a> for related options. +<p class="level1">If this option is used several times, the following occurrences make no difference. +<p class="level0"><a name="--disable-eprt"></a><span class="nroffip">--disable-eprt</span> +<p class="level1">(FTP) Tell curl to disable the use of the EPRT and LPRT commands when doing active FTP transfers. Curl will normally always first attempt to use EPRT, then LPRT before using PORT, but with this option, it will use PORT right away. EPRT and LPRT are extensions to the original FTP protocol, and may not work on all servers, but they enable more functionality in a better way than the traditional PORT command. +<p class="level1"><span Class="bold">--eprt</span> can be used to explicitly enable EPRT again and <span Class="bold">--no-eprt</span> is an alias for <a class="bold" href="#--disable-eprt">--disable-eprt</a>. +<p class="level1">Disabling EPRT only changes the active behavior. If you want to switch to passive mode you need to not use <a class="emphasis" href="#-P--ftp-port">-P/--ftp-port</a> or force it with <a class="emphasis" href="#--ftp-pasv">--ftp-pasv</a>. +<p class="level0"><a name="--disable-epsv"></a><span class="nroffip">--disable-epsv</span> +<p class="level1">(FTP) Tell curl to disable the use of the EPSV command when doing passive FTP transfers. Curl will normally always first attempt to use EPSV before PASV, but with this option, it will not try using EPSV. +<p class="level1"><span Class="bold">--epsv</span> can be used to explicitly enable EPRT again and <span Class="bold">--no-epsv</span> is an alias for <a class="bold" href="#--disable-epsv">--disable-epsv</a>. +<p class="level1">Disabling EPSV only changes the passive behavior.

Cookies from the headers could then be read in a second curl invocation by using the <a class="emphasis" href="#-b--cookie">-b/--cookie</a> option! The <a class="emphasis" href="#-c--cookie-jar">-c/--cookie-jar</a> option is however a better way to store cookies. +<p class="level1">When used in FTP, the FTP server response lines are considered being "headers" and thus are saved there. +<p class="level1">If this option is used several times, the last one will be used. +<p class="level0"><a name="-e--referer"></a><span class="nroffip">-e/--referer <URL></span> +<p class="level1">(HTTP) Sends the "Referer Page" information to the HTTP server. This can also be set with the <a class="emphasis" href="#-H--header">-H/--header</a> flag of course. When used with <a class="emphasis" href="#-L--location">-L/--location</a> you can append ";auto" to the --referer URL to make curl automatically set the previous URL when it follows a Location: header. The ";auto" string can be used alone, even if you don't set an initial --referer. +<p class="level1">If this option is used several times, the last one will be used. +<p class="level0"><a name="--engine"></a><span class="nroffip">--engine <name></span> +<p class="level1">Select the OpenSSL crypto engine to use for cipher operations. Use <a class="emphasis" href="#--engine">--engine list</a> to print a list of build-time supported engines. Note that not all (or none) of the engines may be available at run-time. +<p class="level0"><a name="--environment"></a><span class="nroffip">--environment</span> +<p class="level1">(RISC OS ONLY) Sets a range of environment variables, using the names the -w option supports, to allow easier extraction of useful information after having run curl. +<p class="level0"><a name="--egd-file"></a><span class="nroffip">--egd-file <file></span> +<p class="level1">(SSL) Specify the path name to the Entropy Gathering Daemon socket.

The certificate must be in PEM format. If the optional password isn't specified, it will be queried for on the terminal. Note that this option assumes a "certificate" file that is the private key and the private certificate concatenated! See <span Class="emphasis">--cert</span> and <a class="emphasis" href="#--key">--key</a> to specify them independently. +<p class="level1">If curl is built against the NSS SSL library then this option tells curl the nickname of the certificate to use within the NSS database defined by the environment variable SSL_DIR (or by default /etc/pki/nssdb).

The certificates must be in PEM format, and the directory must have been processed using the c_rehash utility supplied with openssl. Using <a class="emphasis" href="#--capath">--capath</a> can allow curl to make SSL-connections much more efficiently than using <a class="emphasis" href="#--cacert">--cacert</a> if the <a class="emphasis" href="#--cacert">--cacert</a> file contains many CA certificates. +<p class="level1">If this option is used several times, the last one will be used. +<p class="level0"><a name="-f--fail"></a><span class="nroffip">-f/--fail</span> +<p class="level1">(HTTP) Fail silently (no output at all) on server errors. This is mostly done to better enable scripts etc to better deal with failed attempts. In normal cases when a HTTP server fails to deliver a document, it returns an HTML document stating so (which often also describes why and more). This flag will prevent curl from outputting that and return error 22. +<p class="level1">This method is not fail-safe and there are occasions where non-successful response codes will slip through, especially when authentication is involved (response codes 401 and 407). +<p class="level0"><a name="--ftp-account"></a><span class="nroffip">--ftp-account [data]</span> +<p class="level1">(FTP) When an FTP server asks for "account data" after user name and password has been provided, this data is sent off using the ACCT command.
