       git-apply - Apply a patch to files and/or to the index


       git apply [--stat] [--numstat] [--summary] [--check] [--index | --intent-to-add] [--3way]
                 [--apply] [--no-add] [--build-fake-ancestor=<file>] [-R | --reverse]
                 [--allow-binary-replacement | --binary] [--reject] [-z]
                 [-p<n>] [-C<n>] [--inaccurate-eof] [--recount] [--cached]
                 [--ignore-space-change | --ignore-whitespace]
                 [--exclude=<path>] [--include=<path>] [--directory=<root>]
                 [--verbose | --quiet] [--unsafe-paths] [--allow-empty] [<patch>...]


       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

       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.


           The files to read the patch from.  - can be used to read from the
           standard input.

           Instead of applying the patch, output diffstat for the input. Turns
           off "apply".

           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".

           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".

           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".

           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.

           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.

           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.

           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

           When a pure mode change is encountered (which has no index
           information), the information is read from the current index

       -R, --reverse
           Apply the patch in reverse.

           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

           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

           Remove <n> leading path components (separated by slashes) from
           traditional diff paths. E.g., with -p2, a patch against a/dir/file
           will be applied directly to file. The default is 1.

           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.

           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

           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.

           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.

           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.

           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.

           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:

           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.

           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.

           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).

           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/ to
           b/ can be applied to the file in the working tree
           modules/git-gui/ by running git apply

           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.

           Don't return error for patches containing no diff. This includes
           empty patches and patches with commit text only.


           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.

           When no --whitespace flag is given from the command line, this
           configuration item is used as the default.


       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.
