Instead of applying the patch, output diffstat for the
input. Turns off "apply".
Instead of applying the patch, output diffstat for the
input. Turns off "apply".
+--numstat::
+ Similar to \--stat, but shows number of added and
+ deleted lines in decimal notation and 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

up-to-date, it is flagged as an error. This flag also
causes the index file to be updated.
---show-files::
- Show summary of files that are affected by the patch.
+--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 is 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, linkgit:git-apply[1] 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 showing the index information, do not munge paths,
+ but use NUL terminated machine readable format. Without
+ this flag, the pathnames output will have TAB, LF, and
+ backslash characters replaced with `\t`, `\n`, and `\\`,
+ respectively.
+
+-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, linkgit:git-apply[1] 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 are
+discouraged.

information you asked 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 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.
+
+--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 linkgit:git-apply[1] is used for statistics and not applying a
+patch, it defaults to `nowarn`.
++
+You can use different `<action>` 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 whitespaces 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.
+
+--directory=<root>::
+ Prepend <root> to all filenames. If a "-p" argument was passed, too,
+ 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.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 linkgit:git-apply[1]
+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 of presence of the corresponding
+subdirectory is checked and (if possible) updated.
