24 Reads the supplied diff output (i.e. "a patch") and applies it to files.
25 When running from a subdirectory in a repository, patched paths
26 outside the directory are ignored.
27 With the `--index` option, the patch is also applied to the index, and
28 with the `--cached` option, the patch is only applied to the index.
29 Without these options, the command applies the patch only to files,
30 and does not require them to be in a Git repository.
32 This command applies the patch but does not create a commit. Use
33 linkgit:git-am[1] to create commits from patches generated by
34 linkgit:git-format-patch[1] and/or received by email.
39 The files to read the patch from. '-' can be used to read
40 from the standard input.
43 Instead of applying the patch, output diffstat for the
44 input. Turns off "apply".
47 Similar to `--stat`, but shows the number of added and
48 deleted lines in decimal notation and the pathname without
49 abbreviation, to make it more machine friendly. For
50 binary files, outputs two `-` instead of saying
51 `0 0`. Turns off "apply".
54 Instead of applying the patch, output a condensed
55 summary of information obtained from git diff extended
56 headers, such as creations, renames, and mode changes.
60 Instead of applying the patch, see if the patch is
61 applicable to the current working tree and/or the index
62 file and detects errors. Turns off "apply".
65 Apply the patch to both the index and the working tree (or
66 merely check that it would apply cleanly to both if `--check` is
67 in effect). Note that `--index` expects index entries and
68 working tree copies for relevant paths to be identical (their
69 contents and metadata such as file mode must match), and will
70 raise an error if they are not, even if the patch would apply
71 cleanly to both the index and the working tree in isolation.
74 Apply the patch to just the index, without touching the working
75 tree. If `--check` is in effect, merely check that it would
76 apply cleanly to the index entry.
79 When applying the patch only to the working tree, mark new
80 files to be added to the index later (see `--intent-to-add`
81 option in linkgit:git-add[1]). This option is ignored unless
82 running in a Git repository and `--index` is not specified.
83 Note that `--index` could be implied by other options such
84 as `--cached` or `--3way`.
88 Attempt 3-way merge if the patch records the identity of blobs it is supposed
89 to apply to and we have those blobs available locally, possibly leaving the
90 conflict markers in the files in the working tree for the user to
91 resolve. This option implies the `--index` option unless the
92 `--cached` option is used, and is incompatible with the `--reject` option.
93 When used with the `--cached` option, any conflicts are left at higher stages
99 Instead of leaving conflicts in the file, resolve conflicts favouring
100 our (or their or both) side of the lines. Requires --3way.
102 --build-fake-ancestor=<file>::
103 Newer 'git diff' output has embedded 'index information'
104 for each blob to help identify the original version that
105 the patch applies to. When this flag is given, and if
106 the original versions of the blobs are available locally,
107 builds a temporary index containing those blobs.
109 When a pure mode change is encountered (which has no index information),
110 the information is read from the current index instead.
114 Apply the patch in reverse.
117 For atomicity, 'git apply' by default fails the whole patch and
118 does not touch the working tree when some of the hunks
119 do not apply. This option makes it apply
120 the parts of the patch that are applicable, and leave the
121 rejected hunks in corresponding *.rej files.
124 When `--numstat` has been given, do not munge pathnames,
125 but use a NUL-terminated machine-readable format.
127 Without this option, pathnames with "unusual" characters are quoted as
128 explained for the configuration variable `core.quotePath` (see
129 linkgit:git-config[1]).
132 Remove <n> leading path components (separated by slashes) from
133 traditional diff paths. E.g., with `-p2`, a patch against
134 `a/dir/file` will be applied directly to `file`. The default is
138 Ensure at least <n> lines of surrounding context match before
139 and after each change. When fewer lines of surrounding
140 context exist they all must match. By default no context is
144 By default, 'git apply' expects that the patch being
145 applied is a unified diff with at least one line of context.
146 This provides good safety measures, but breaks down when
147 applying a diff generated with `--unified=0`. To bypass these
148 checks use `--unidiff-zero`.
150 Note, for the reasons stated above, the usage of context-free patches is
154 If you use any of the options marked "Turns off
155 'apply'" above, 'git apply' reads and outputs the
156 requested information without actually applying the
157 patch. Give this flag after those flags to also apply
161 When applying a patch, ignore additions made by the
162 patch. This can be used to extract the common part between
163 two files by first running 'diff' on them and applying
164 the result with this option, which would apply the
165 deletion part but not the addition part.
167 --allow-binary-replacement::
169 Historically we did not allow binary patch application
170 without an explicit permission from the user, and this
171 flag was the way to do so. Currently, we always allow binary
172 patch application, so this is a no-op.
174 --exclude=<path-pattern>::
175 Don't apply changes to files matching the given path pattern. This can
176 be useful when importing patchsets, where you want to exclude certain
177 files or directories.
179 --include=<path-pattern>::
180 Apply changes to files matching the given path pattern. This can
181 be useful when importing patchsets, where you want to include certain
182 files or directories.
184 When `--exclude` and `--include` patterns are used, they are examined in the
185 order they appear on the command line, and the first match determines if a
186 patch to each path is used. A patch to a path that does not match any
187 include/exclude pattern is used by default if there is no include pattern
188 on the command line, and ignored if there is any include pattern.
190 --ignore-space-change::
191 --ignore-whitespace::
192 When applying a patch, ignore changes in whitespace in context
194 Context lines will preserve their whitespace, and they will not
195 undergo whitespace fixing regardless of the value of the
196 `--whitespace` option. New lines will still be fixed, though.
198 --whitespace=<action>::
199 When applying a patch, detect a new or modified line that has
200 whitespace errors. What are considered whitespace errors is
201 controlled by `core.whitespace` configuration. By default,
202 trailing whitespaces (including lines that solely consist of
203 whitespaces) and a space character that is immediately followed
204 by a tab character inside the initial indent of the line are
205 considered whitespace errors.
207 By default, the command outputs warning messages but applies the patch.
208 When `git-apply` is used for statistics and not applying a
209 patch, it defaults to `nowarn`.
211 You can use different `<action>` values to control this
214 * `nowarn` turns off the trailing whitespace warning.
215 * `warn` outputs warnings for a few such errors, but applies the
216 patch as-is (default).
217 * `fix` outputs warnings for a few such errors, and applies the
218 patch after fixing them (`strip` is a synonym -- the tool
219 used to consider only trailing whitespace characters as errors, and the
220 fix involved 'stripping' them, but modern Gits do more).
221 * `error` outputs warnings for a few such errors, and refuses
223 * `error-all` is similar to `error` but shows all errors.
226 Under certain circumstances, some versions of 'diff' do not correctly
227 detect a missing new-line at the end of the file. As a result, patches
228 created by such 'diff' programs do not record incomplete lines
229 correctly. This option adds support for applying such patches by
230 working around this bug.
234 Report progress to stderr. By default, only a message about the
235 current patch being applied will be printed. This option will cause
236 additional information to be reported.
240 Suppress stderr output. Messages about patch status and progress
244 Do not trust the line counts in the hunk headers, but infer them
245 by inspecting the patch (e.g. after editing the patch without
246 adjusting the hunk headers appropriately).
249 Prepend <root> to all filenames. If a "-p" argument was also passed,
250 it is applied before prepending the new root.
252 For example, a patch that talks about updating `a/git-gui.sh` to `b/git-gui.sh`
253 can be applied to the file in the working tree `modules/git-gui/git-gui.sh` by
254 running `git apply --directory=modules/git-gui`.
257 By default, a patch that affects outside the working area
258 (either a Git controlled working tree, or the current working
259 directory when "git apply" is used as a replacement of GNU
260 patch) is rejected as a mistake (or a mischief).
262 When `git apply` is used as a "better GNU patch", the user can pass
263 the `--unsafe-paths` option to override this safety check. This option
264 has no effect when `--index` or `--cached` is in use.
267 Don't return an error for patches containing no diff. This includes
268 empty patches and patches with commit text only.
273 include::includes/cmd-config-section-all.txt[]
275 include::config/apply.txt[]
279 If the patch contains any changes to submodules then 'git apply'
280 treats these changes as follows.
282 If `--index` is specified (explicitly or implicitly), then the submodule
283 commits must match the index exactly for the patch to apply. If any
284 of the submodules are checked-out, then these check-outs are completely
285 ignored, i.e., they are not required to be up to date or clean and they
288 If `--index` is not specified, then the submodule commits in the patch
289 are ignored and only the absence or presence of the corresponding
290 subdirectory is checked and (if possible) updated.
