+DESCRIPTION
+-----------
+Reads the supplied diff output (i.e. "a patch") and applies it to files.
+With the `--index` option the patch is also applied to the index, and
+with the `--cache` option the patch is only applied to the index.
+Without these options, the command applies the patch only to files,
+and does not require them to be in a git repository.
+
+This command applies the patch but does not create a commit.  Use
+linkgit:git-am[1] to create commits from patches generated by
+linkgit:git-format-patch[1] and/or received by email.
+
+OPTIONS
+-------
+<patch>...::
+	The files to read the patch from.  '-' can be used to read
+	from the standard input.
+
+--stat::
+	Instead of applying the patch, output diffstat for the
+	input.  Turns off "apply".
+
+--numstat::
+	Similar to `--stat`, but shows the number of added and
+	deleted lines in decimal notation and the pathname without
+	abbreviation, to make it more machine friendly.  For
+	binary files, outputs two `-` instead of saying
+	`0 0`.  Turns off "apply".
+
+--summary::
+	Instead of applying the patch, output a condensed
+	summary of information obtained from git diff extended
+	headers, such as creations, renames and mode changes.
+	Turns off "apply".
+
+--check::
+	Instead of applying the patch, see if the patch is
+	applicable to the current working tree and/or the index
+	file and detects errors.  Turns off "apply".
+
+--index::
+	When `--check` is in effect, or when applying the patch
+	(which is the default when none of the options that
+	disables it is in effect), make sure the patch is
+	applicable to what the current index file records.  If
+	the file to be patched in the working tree is not
+	up-to-date, it is flagged as an error.  This flag also
+	causes the index file to be updated.
+
+--cached::
+	Apply a patch without touching the working tree. Instead take the
+	cached data, apply the patch, and store the result in the index
+	without using the working tree. This implies `--index`.
+
+--build-fake-ancestor=<file>::
+	Newer 'git diff' output has embedded 'index information'
+	for each blob to help identify the original version that
+	the patch applies to.  When this flag is given, and if
+	the original versions of the blobs are available locally,
+	builds a temporary index containing those blobs.
++
+When a pure mode change is encountered (which has no index information),
+the information is read from the current index instead.
+
+-R::
+--reverse::
+	Apply the patch in reverse.
+
+--reject::
+	For atomicity, 'git apply' by default fails the whole patch and
+	does not touch the working tree when some of the hunks
+	do not apply.  This option makes it apply
+	the parts of the patch that are applicable, and leave the
+	rejected hunks in corresponding *.rej files.
+
+-z::
+	When `--numstat` has been given, do not munge pathnames,
+	but use a NUL-terminated machine-readable format.
++
+Without this option, each pathname output will have TAB, LF, double quotes,
+and backslash characters replaced with `\t`, `\n`, `\"`, and `\\`,
+respectively, and the pathname will be enclosed in double quotes if
+any of those replacements occurred.
+
+-p<n>::
+	Remove <n> leading slashes from traditional diff paths. The
+	default is 1.
+
+-C<n>::
+	Ensure at least <n> lines of surrounding context match before
+	and after each change.  When fewer lines of surrounding
+	context exist they all must match.  By default no context is
+	ever ignored.
+
+--unidiff-zero::
+	By default, 'git apply' expects that the patch being
+	applied is a unified diff with at least one line of context.
+	This provides good safety measures, but breaks down when
+	applying a diff generated with `--unified=0`. To bypass these
+	checks use `--unidiff-zero`.
++
+Note, for the reasons stated above usage of context-free patches is
+discouraged.
+
+--apply::
+	If you use any of the options marked "Turns off
+	'apply'" above, 'git apply' reads and outputs the
+	requested information without actually applying the
+	patch.  Give this flag after those flags to also apply
+	the patch.
+
+--no-add::
+	When applying a patch, ignore additions made by the
+	patch.  This can be used to extract the common part between
+	two files by first running 'diff' on them and applying
+	the result with this option, which would apply the
+	deletion part but not the addition part.
+
+--allow-binary-replacement::
+--binary::
+	Historically we did not allow binary patch applied
+	without an explicit permission from the user, and this
+	flag was the way to do so.  Currently we always allow binary
+	patch application, so this is a no-op.
+
+--exclude=<path-pattern>::
+	Don't apply changes to files matching the given path pattern. This can
+	be useful when importing patchsets, where you want to exclude certain
+	files or directories.
+
+--include=<path-pattern>::
+	Apply changes to files matching the given path pattern. This can
+	be useful when importing patchsets, where you want to include certain
+	files or directories.
++
+When `--exclude` and `--include` patterns are used, they are examined in the
+order they appear on the command line, and the first match determines if a
+patch to each path is used.  A patch to a path that does not match any
+include/exclude pattern is used by default if there is no include pattern
+on the command line, and ignored if there is any include pattern.
+
+--ignore-space-change::
+--ignore-whitespace::
+	When applying a patch, ignore changes in whitespace in context
+	lines if necessary.
+	Context lines will preserve their whitespace, and they will not
+	undergo whitespace fixing regardless of the value of the
+	`--whitespace` option. New lines will still be fixed, though.
+
+--whitespace=<action>::
+	When applying a patch, detect a new or modified line that has
+	whitespace errors.  What are considered whitespace errors is
+	controlled by `core.whitespace` configuration.  By default,
+	trailing whitespaces (including lines that solely consist of
+	whitespaces) and a space character that is immediately followed
+	by a tab character inside the initial indent of the line are
+	considered whitespace errors.
++
+By default, the command outputs warning messages but applies the patch.
+When `git-apply` is used for statistics and not applying a
+patch, it defaults to `nowarn`.
++
+You can use different `<action>` values to control this
+behavior:
++
+* `nowarn` turns off the trailing whitespace warning.
+* `warn` outputs warnings for a few such errors, but applies the
+  patch as-is (default).
+* `fix` outputs warnings for a few such errors, and applies the
+  patch after fixing them (`strip` is a synonym --- the tool
+  used to consider only trailing whitespace characters as errors, and the
+  fix involved 'stripping' them, but modern gits do more).
+* `error` outputs warnings for a few such errors, and refuses
+  to apply the patch.
+* `error-all` is similar to `error` but shows all errors.
+
+--inaccurate-eof::
+	Under certain circumstances, some versions of 'diff' do not correctly
+	detect a missing new-line at the end of the file. As a result, patches
+	created by such 'diff' programs do not record incomplete lines
+	correctly. This option adds support for applying such patches by
+	working around this bug.
+
+-v::
+--verbose::
+	Report progress to stderr. By default, only a message about the
+	current patch being applied will be printed. This option will cause
+	additional information to be reported.
+
+--recount::
+	Do not trust the line counts in the hunk headers, but infer them
+	by inspecting the patch (e.g. after editing the patch without
+	adjusting the hunk headers appropriately).
+
+--directory=<root>::
+	Prepend <root> to all filenames.  If a "-p" argument was also passed,
+	it is applied before prepending the new root.
++
+For example, a patch that talks about updating `a/git-gui.sh` to `b/git-gui.sh`
+can be applied to the file in the working tree `modules/git-gui/git-gui.sh` by
+running `git apply --directory=modules/git-gui`.
+
+Configuration
+-------------
+
+apply.ignorewhitespace::
+	Set to 'change' if you want changes in whitespace to be ignored by default.
+	Set to one of: no, none, never, false if you want changes in
+	whitespace to be significant.
+apply.whitespace::
+	When no `--whitespace` flag is given from the command
+	line, this configuration item is used as the default.
+
+Submodules
+----------
+If the patch contains any changes to submodules then 'git apply'
+treats these changes as follows.
+
+If `--index` is specified (explicitly or implicitly), then the submodule
+commits must match the index exactly for the patch to apply.  If any
+of the submodules are checked-out, then these check-outs are completely
+ignored, i.e., they are not required to be up-to-date or clean and they
+are not updated.
+
+If `--index` is not specified, then the submodule commits in the patch
+are ignored and only the absence or presence of the corresponding
+subdirectory is checked and (if possible) updated.
