          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]

                    [--verbose] [--unsafe-paths] [<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 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.

              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".

     GIT-APPLY(1)              (08/17/2021)               GIT-APPLY(1)

              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 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.

     GIT-APPLY(1)              (08/17/2021)               GIT-APPLY(1)

              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.

              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)).

              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 discouraged.

              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

     Page 3                     Git 2.33.0           (printed 1/20/22)

     GIT-APPLY(1)              (08/17/2021)               GIT-APPLY(1)

              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.

              Doncqt 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

              +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

     GIT-APPLY(1)              (08/17/2021)               GIT-APPLY(1)

                  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

              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

              Prepend <root> to all filenames. If a "-p" argument was
              also passed, it is applied before prepending the new

              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 --directory=modules/git-gui.

              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

              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.

              ignored by default. Set to one of: no, none, never,
              false if you want changes in whitespace to be

              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)
