DESCRIPTION
Reads the supplied diff output (i.e. "a patch") and applies it to files.
When running from a subdirectory in a repository, patched paths
outside the directory are ignored.
With the --index
option, the patch is also applied to the index, and
with the --cached
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 git-am(1) to create commits from patches generated by 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 saying0 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
-
Apply the patch to both the index and the working tree (or merely check that it would apply cleanly to both if
--check
is in effect). Note that--index
expects index entries and working tree copies for relevant paths to be identical (their contents and metadata such as file mode must match), and will raise an error if they are not, even if the patch would apply cleanly to both the index and the working tree in isolation. - --cached
-
Apply the patch to just the index, without touching the working tree. If
--check
is in effect, merely check that it would apply cleanly to the index entry. - --intent-to-add
-
When applying the patch only to the working tree, mark new files to be added to the index later (see
--intent-to-add
option in git-add(1)). This option is ignored unless running in a Git repository and--index
is not specified. Note that--index
could be implied by other options such as--cached
or--3way
. - -3
- --3way
-
Attempt 3-way merge if the patch records the identity of blobs it is supposed to apply to and we have those blobs available locally, possibly leaving the conflict markers in the files in the working tree for the user to resolve. This option implies the
--index
option unless the--cached
option is used, and is incompatible with the--reject
option. When used with the--cached
option, any conflicts are left at higher stages in the cache. - --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, pathnames with "unusual" characters are quoted as explained for the configuration variable
core.quotePath
(see git-config(1)). - -p<n>
-
Remove <n> leading path components (separated by slashes) from traditional diff paths. E.g., with
-p2
, a patch againsta/dir/file
will be applied directly tofile
. 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, the 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 application 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 tonowarn
.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 toerror
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.
- -q
- --quiet
-
Suppress stderr output. Messages about patch status and progress will not be printed.
- --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
tob/git-gui.sh
can be applied to the file in the working treemodules/git-gui/git-gui.sh
by runninggit apply --directory=modules/git-gui
. - --unsafe-paths
-
By default, a patch that affects outside the working area (either a Git controlled working tree, or the current working directory when "git apply" is used as a replacement of GNU patch) is rejected as a mistake (or a mischief).
When
git apply
is used as a "better GNU patch", the user can pass the--unsafe-paths
option to override this safety check. This option has no effect when--index
or--cached
is in use. - --allow-empty
-
Don’t return an error for patches containing no diff. This includes empty patches and patches with commit text only.
CONFIGURATION
Everything below this line in this section is selectively included from the git-config(1) documentation. The content is the same as what’s found there:
- apply.ignoreWhitespace
-
When set to change, tells git apply to ignore changes in whitespace, in the same way as the
--ignore-space-change
option. When set to one of: no, none, never, false, it tells git apply to respect all whitespace differences. See git-apply(1). - apply.whitespace
-
Tells git apply how to handle whitespace, in the same way as the
--whitespace
option. See git-apply(1).
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.
