23 Reads the supplied diff output (i.e. "a patch") and applies it to files.
24 When running from a subdirectory in a repository, patched paths
25 outside the directory are ignored.
26 With the `--index` option the patch is also applied to the index, and
27 with the `--cached` option the patch is only applied to the index.
28 Without these options, the command applies the patch only to files,
29 and does not require them to be in a Git repository.
31 This command applies the patch but does not create a commit. Use
32 linkgit:git-am[1] to create commits from patches generated by
33 linkgit:git-format-patch[1] and/or received by email.
38 The files to read the patch from. '-' can be used to read
39 from the standard input.
42 Instead of applying the patch, output diffstat for the
43 input. Turns off "apply".
46 Similar to `--stat`, but shows the number of added and
47 deleted lines in decimal notation and the pathname without
48 abbreviation, to make it more machine friendly. For
49 binary files, outputs two `-` instead of saying
50 `0 0`. Turns off "apply".
53 Instead of applying the patch, output a condensed
54 summary of information obtained from git diff extended
55 headers, such as creations, renames and mode changes.
59 Instead of applying the patch, see if the patch is
60 applicable to the current working tree and/or the index
61 file and detects errors. Turns off "apply".
64 Apply the patch to both the index and the working tree (or
65 merely check that it would apply cleanly to both if `--check` is
66 in effect). Note that `--index` expects index entries and
67 working tree copies for relevant paths to be identical (their
68 contents and metadata such as file mode must match), and will
69 raise an error if they are not, even if the patch would apply
70 cleanly to both the index and the working tree in isolation.
73 Apply the patch to just the index, without touching the working
74 tree. If `--check` is in effect, merely check that it would
75 apply cleanly to the index entry.
78 When applying the patch only to the working tree, mark new
79 files to be added to the index later (see `--intent-to-add`
80 option in linkgit:git-add[1]). This option is ignored unless
81 running in a Git repository and `--index` is not specified.
82 Note that `--index` could be implied by other options such
83 as `--cached` or `--3way`.
87 When the patch does not apply cleanly, fall back on 3-way merge if
88 the patch records the identity of blobs it is supposed to apply to,
89 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, and is incompatible
92 with the `--reject` and the `--cached` options.
94 --build-fake-ancestor=<file>::
95 Newer 'git diff' output has embedded 'index information'
96 for each blob to help identify the original version that
97 the patch applies to. When this flag is given, and if
98 the original versions of the blobs are available locally,
99 builds a temporary index containing those blobs.
101 When a pure mode change is encountered (which has no index information),
102 the information is read from the current index instead.
106 Apply the patch in reverse.
109 For atomicity, 'git apply' by default fails the whole patch and
110 does not touch the working tree when some of the hunks
111 do not apply. This option makes it apply
112 the parts of the patch that are applicable, and leave the
113 rejected hunks in corresponding *.rej files.
116 When `--numstat` has been given, do not munge pathnames,
117 but use a NUL-terminated machine-readable format.
119 Without this option, pathnames with "unusual" characters are quoted as
120 explained for the configuration variable `core.quotePath` (see
121 linkgit:git-config[1]).
124 Remove <n> leading path components (separated by slashes) from
125 traditional diff paths. E.g., with `-p2`, a patch against
126 `a/dir/file` will be applied directly to `file`. The default is
130 Ensure at least <n> lines of surrounding context match before
131 and after each change. When fewer lines of surrounding
132 context exist they all must match. By default no context is
136 By default, 'git apply' expects that the patch being
137 applied is a unified diff with at least one line of context.
138 This provides good safety measures, but breaks down when
139 applying a diff generated with `--unified=0`. To bypass these
140 checks use `--unidiff-zero`.
142 Note, for the reasons stated above usage of context-free patches is
146 If you use any of the options marked "Turns off
147 'apply'" above, 'git apply' reads and outputs the
148 requested information without actually applying the
149 patch. Give this flag after those flags to also apply
153 When applying a patch, ignore additions made by the
154 patch. This can be used to extract the common part between
155 two files by first running 'diff' on them and applying
156 the result with this option, which would apply the
157 deletion part but not the addition part.
159 --allow-binary-replacement::
161 Historically we did not allow binary patch applied
162 without an explicit permission from the user, and this
163 flag was the way to do so. Currently we always allow binary
164 patch application, so this is a no-op.
166 --exclude=<path-pattern>::
167 Don't apply changes to files matching the given path pattern. This can
168 be useful when importing patchsets, where you want to exclude certain
169 files or directories.
171 --include=<path-pattern>::
172 Apply changes to files matching the given path pattern. This can
173 be useful when importing patchsets, where you want to include certain
174 files or directories.
176 When `--exclude` and `--include` patterns are used, they are examined in the
177 order they appear on the command line, and the first match determines if a
178 patch to each path is used. A patch to a path that does not match any
179 include/exclude pattern is used by default if there is no include pattern
180 on the command line, and ignored if there is any include pattern.
182 --ignore-space-change::
183 --ignore-whitespace::
184 When applying a patch, ignore changes in whitespace in context
186 Context lines will preserve their whitespace, and they will not
187 undergo whitespace fixing regardless of the value of the
188 `--whitespace` option. New lines will still be fixed, though.
190 --whitespace=<action>::
191 When applying a patch, detect a new or modified line that has
192 whitespace errors. What are considered whitespace errors is
193 controlled by `core.whitespace` configuration. By default,
194 trailing whitespaces (including lines that solely consist of
195 whitespaces) and a space character that is immediately followed
196 by a tab character inside the initial indent of the line are
197 considered whitespace errors.
199 By default, the command outputs warning messages but applies the patch.
200 When `git-apply` is used for statistics and not applying a
201 patch, it defaults to `nowarn`.
203 You can use different `<action>` values to control this
206 * `nowarn` turns off the trailing whitespace warning.
207 * `warn` outputs warnings for a few such errors, but applies the
208 patch as-is (default).
209 * `fix` outputs warnings for a few such errors, and applies the
210 patch after fixing them (`strip` is a synonym --- the tool
211 used to consider only trailing whitespace characters as errors, and the
212 fix involved 'stripping' them, but modern Gits do more).
213 * `error` outputs warnings for a few such errors, and refuses
215 * `error-all` is similar to `error` but shows all errors.
218 Under certain circumstances, some versions of 'diff' do not correctly
219 detect a missing new-line at the end of the file. As a result, patches
220 created by such 'diff' programs do not record incomplete lines
221 correctly. This option adds support for applying such patches by
222 working around this bug.
226 Report progress to stderr. By default, only a message about the
227 current patch being applied will be printed. This option will cause
228 additional information to be reported.
231 Do not trust the line counts in the hunk headers, but infer them
232 by inspecting the patch (e.g. after editing the patch without
233 adjusting the hunk headers appropriately).
236 Prepend <root> to all filenames. If a "-p" argument was also passed,
237 it is applied before prepending the new root.
239 For example, a patch that talks about updating `a/git-gui.sh` to `b/git-gui.sh`
240 can be applied to the file in the working tree `modules/git-gui/git-gui.sh` by
241 running `git apply --directory=modules/git-gui`.
244 By default, a patch that affects outside the working area
245 (either a Git controlled working tree, or the current working
246 directory when "git apply" is used as a replacement of GNU
247 patch) is rejected as a mistake (or a mischief).
249 When `git apply` is used as a "better GNU patch", the user can pass
250 the `--unsafe-paths` option to override this safety check. This option
251 has no effect when `--index` or `--cached` is in use.
256 apply.ignoreWhitespace::
257 Set to 'change' if you want changes in whitespace to be ignored by default.
258 Set to one of: no, none, never, false if you want changes in
259 whitespace to be significant.
261 When no `--whitespace` flag is given from the command
262 line, this configuration item is used as the default.
266 If the patch contains any changes to submodules then 'git apply'
267 treats these changes as follows.
269 If `--index` is specified (explicitly or implicitly), then the submodule
270 commits must match the index exactly for the patch to apply. If any
271 of the submodules are checked-out, then these check-outs are completely
272 ignored, i.e., they are not required to be up to date or clean and they
275 If `--index` is not specified, then the submodule commits in the patch
276 are ignored and only the absence or presence of the corresponding
277 subdirectory is checked and (if possible) updated.
