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 When `--check` is in effect, or when applying the patch
65 (which is the default when none of the options that
66 disables it is in effect), make sure the patch is
67 applicable to what the current index file records. If
68 the file to be patched in the working tree is not
69 up-to-date, it is flagged as an error. This flag also
70 causes the index file to be updated.
73 Apply a patch without touching the working tree. Instead take the
74 cached data, apply the patch, and store the result in the index
75 without using the working tree. This implies `--index`.
79 When the patch does not apply cleanly, fall back on 3-way merge if
80 the patch records the identity of blobs it is supposed to apply to,
81 and we have those blobs available locally, possibly leaving the
82 conflict markers in the files in the working tree for the user to
83 resolve. This option implies the `--index` option, and is incompatible
84 with the `--reject` and the `--cached` options.
86 --build-fake-ancestor=<file>::
87 Newer 'git diff' output has embedded 'index information'
88 for each blob to help identify the original version that
89 the patch applies to. When this flag is given, and if
90 the original versions of the blobs are available locally,
91 builds a temporary index containing those blobs.
93 When a pure mode change is encountered (which has no index information),
94 the information is read from the current index instead.
98 Apply the patch in reverse.
101 For atomicity, 'git apply' by default fails the whole patch and
102 does not touch the working tree when some of the hunks
103 do not apply. This option makes it apply
104 the parts of the patch that are applicable, and leave the
105 rejected hunks in corresponding *.rej files.
108 When `--numstat` has been given, do not munge pathnames,
109 but use a NUL-terminated machine-readable format.
111 Without this option, each pathname output will have TAB, LF, double quotes,
112 and backslash characters replaced with `\t`, `\n`, `\"`, and `\\`,
113 respectively, and the pathname will be enclosed in double quotes if
114 any of those replacements occurred.
117 Remove <n> leading slashes from traditional diff paths. The
121 Ensure at least <n> lines of surrounding context match before
122 and after each change. When fewer lines of surrounding
123 context exist they all must match. By default no context is
127 By default, 'git apply' expects that the patch being
128 applied is a unified diff with at least one line of context.
129 This provides good safety measures, but breaks down when
130 applying a diff generated with `--unified=0`. To bypass these
131 checks use `--unidiff-zero`.
133 Note, for the reasons stated above usage of context-free patches is
137 If you use any of the options marked "Turns off
138 'apply'" above, 'git apply' reads and outputs the
139 requested information without actually applying the
140 patch. Give this flag after those flags to also apply
144 When applying a patch, ignore additions made by the
145 patch. This can be used to extract the common part between
146 two files by first running 'diff' on them and applying
147 the result with this option, which would apply the
148 deletion part but not the addition part.
150 --allow-binary-replacement::
152 Historically we did not allow binary patch applied
153 without an explicit permission from the user, and this
154 flag was the way to do so. Currently we always allow binary
155 patch application, so this is a no-op.
157 --exclude=<path-pattern>::
158 Don't apply changes to files matching the given path pattern. This can
159 be useful when importing patchsets, where you want to exclude certain
160 files or directories.
162 --include=<path-pattern>::
163 Apply changes to files matching the given path pattern. This can
164 be useful when importing patchsets, where you want to include certain
165 files or directories.
167 When `--exclude` and `--include` patterns are used, they are examined in the
168 order they appear on the command line, and the first match determines if a
169 patch to each path is used. A patch to a path that does not match any
170 include/exclude pattern is used by default if there is no include pattern
171 on the command line, and ignored if there is any include pattern.
173 --ignore-space-change::
174 --ignore-whitespace::
175 When applying a patch, ignore changes in whitespace in context
177 Context lines will preserve their whitespace, and they will not
178 undergo whitespace fixing regardless of the value of the
179 `--whitespace` option. New lines will still be fixed, though.
181 --whitespace=<action>::
182 When applying a patch, detect a new or modified line that has
183 whitespace errors. What are considered whitespace errors is
184 controlled by `core.whitespace` configuration. By default,
185 trailing whitespaces (including lines that solely consist of
186 whitespaces) and a space character that is immediately followed
187 by a tab character inside the initial indent of the line are
188 considered whitespace errors.
190 By default, the command outputs warning messages but applies the patch.
191 When `git-apply` is used for statistics and not applying a
192 patch, it defaults to `nowarn`.
194 You can use different `<action>` values to control this
197 * `nowarn` turns off the trailing whitespace warning.
198 * `warn` outputs warnings for a few such errors, but applies the
199 patch as-is (default).
200 * `fix` outputs warnings for a few such errors, and applies the
201 patch after fixing them (`strip` is a synonym --- the tool
202 used to consider only trailing whitespace characters as errors, and the
203 fix involved 'stripping' them, but modern Gits do more).
204 * `error` outputs warnings for a few such errors, and refuses
206 * `error-all` is similar to `error` but shows all errors.
209 Under certain circumstances, some versions of 'diff' do not correctly
210 detect a missing new-line at the end of the file. As a result, patches
211 created by such 'diff' programs do not record incomplete lines
212 correctly. This option adds support for applying such patches by
213 working around this bug.
217 Report progress to stderr. By default, only a message about the
218 current patch being applied will be printed. This option will cause
219 additional information to be reported.
222 Do not trust the line counts in the hunk headers, but infer them
223 by inspecting the patch (e.g. after editing the patch without
224 adjusting the hunk headers appropriately).
227 Prepend <root> to all filenames. If a "-p" argument was also passed,
228 it is applied before prepending the new root.
230 For example, a patch that talks about updating `a/git-gui.sh` to `b/git-gui.sh`
231 can be applied to the file in the working tree `modules/git-gui/git-gui.sh` by
232 running `git apply --directory=modules/git-gui`.
235 By default, a patch that affects outside the working area
236 (either a Git controlled working tree, or the current working
237 directory when "git apply" is used as a replacement of GNU
238 patch) is rejected as a mistake (or a mischief).
240 When `git apply` is used as a "better GNU patch", the user can pass
241 the `--unsafe-paths` option to override this safety check. This option
242 has no effect when `--index` or `--cached` is in use.
247 apply.ignoreWhitespace::
248 Set to 'change' if you want changes in whitespace to be ignored by default.
249 Set to one of: no, none, never, false if you want changes in
250 whitespace to be significant.
252 When no `--whitespace` flag is given from the command
253 line, this configuration item is used as the default.
257 If the patch contains any changes to submodules then 'git apply'
258 treats these changes as follows.
260 If `--index` is specified (explicitly or implicitly), then the submodule
261 commits must match the index exactly for the patch to apply. If any
262 of the submodules are checked-out, then these check-outs are completely
263 ignored, i.e., they are not required to be up-to-date or clean and they
266 If `--index` is not specified, then the submodule commits in the patch
267 are ignored and only the absence or presence of the corresponding
268 subdirectory is checked and (if possible) updated.
