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
git-am(1) to create commits from patches generated by git-for-
mat-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".

GIT-APPLY(1)GIT-APPLY(1)--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 ver-
sions 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
2

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 gen-
erated with --unified=0. To bypass these checks use --unid-
iff-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 pat-
tern. 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 exam-
ined 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.

GIT-APPLY(1)GIT-APPLY(1)--ignore-space-change, --ignore-whitespace
When applying a patch, ignore changes in whitespace in context
lines if necessary. Context lines will preserve their whites-
pace, 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 con-
trolled 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:
o nowarn turns off the trailing whitespace warning.
o warn outputs warnings for a few such errors, but applies the
patch as-is (default).
o 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).
o error outputs warnings for a few such errors, and refuses to
apply the patch.
o error-all is similar to error but shows all errors.
--inaccurate-eof
Under certain circumstances, some versions of diff do not cor-
rectly 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 apply-
ing 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
4
GIT-APPLY(1)GIT-APPLY(1)
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 mod-
ules/git-gui/git-gui.sh by running git apply --directory=mod-
ules/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 sub-
directory is checked and (if possible) updated.
