23 Reads the supplied diff output (i.e. "a patch") and applies it to files.
24 With the `--index` option the patch is also applied to the index, and
25 with the `--cached` option the patch is only applied to the index.
26 Without these options, the command applies the patch only to files,
27 and does not require them to be in a Git repository.
29 This command applies the patch but does not create a commit. Use
30 linkgit:git-am[1] to create commits from patches generated by
31 linkgit:git-format-patch[1] and/or received by email.
36 The files to read the patch from. '-' can be used to read
37 from the standard input.
40 Instead of applying the patch, output diffstat for the
41 input. Turns off "apply".
44 Similar to `--stat`, but shows the number of added and
45 deleted lines in decimal notation and the pathname without
46 abbreviation, to make it more machine friendly. For
47 binary files, outputs two `-` instead of saying
48 `0 0`. Turns off "apply".
51 Instead of applying the patch, output a condensed
52 summary of information obtained from git diff extended
53 headers, such as creations, renames and mode changes.
57 Instead of applying the patch, see if the patch is
58 applicable to the current working tree and/or the index
59 file and detects errors. Turns off "apply".
62 When `--check` is in effect, or when applying the patch
63 (which is the default when none of the options that
64 disables it is in effect), make sure the patch is
65 applicable to what the current index file records. If
66 the file to be patched in the working tree is not
67 up-to-date, it is flagged as an error. This flag also
68 causes the index file to be updated.
74 Apply a patch without touching the working tree. Instead take the
75 cached data, apply the patch, and store the result in the index
76 without using the working tree. This implies `--index`.
79 Apply a patch with or without touching the working tree, essentially
80 `--no-work` plus `--index` are the equivalent of `--cached`.
84 When the patch does not apply cleanly, fall back on 3-way merge if
85 the patch records the identity of blobs it is supposed to apply to,
86 and we have those blobs available locally, possibly leaving the
87 conflict markers in the files in the working tree for the user to
88 resolve. This option implies the `--index` option, and is incompatible
89 with the `--reject` and the `--cached` options.
91 --build-fake-ancestor=<file>::
92 Newer 'git diff' output has embedded 'index information'
93 for each blob to help identify the original version that
94 the patch applies to. When this flag is given, and if
95 the original versions of the blobs are available locally,
96 builds a temporary index containing those blobs.
98 When a pure mode change is encountered (which has no index information),
99 the information is read from the current index instead.
103 Apply the patch in reverse.
106 For atomicity, 'git apply' by default fails the whole patch and
107 does not touch the working tree when some of the hunks
108 do not apply. This option makes it apply
109 the parts of the patch that are applicable, and leave the
110 rejected hunks in corresponding *.rej files.
113 When `--numstat` has been given, do not munge pathnames,
114 but use a NUL-terminated machine-readable format.
116 Without this option, each pathname output will have TAB, LF, double quotes,
117 and backslash characters replaced with `\t`, `\n`, `\"`, and `\\`,
118 respectively, and the pathname will be enclosed in double quotes if
119 any of those replacements occurred.
122 Remove <n> leading slashes from traditional diff paths. The
126 Ensure at least <n> lines of surrounding context match before
127 and after each change. When fewer lines of surrounding
128 context exist they all must match. By default no context is
132 By default, 'git apply' expects that the patch being
133 applied is a unified diff with at least one line of context.
134 This provides good safety measures, but breaks down when
135 applying a diff generated with `--unified=0`. To bypass these
136 checks use `--unidiff-zero`.
138 Note, for the reasons stated above usage of context-free patches is
142 If you use any of the options marked "Turns off
143 'apply'" above, 'git apply' reads and outputs the
144 requested information without actually applying the
145 patch. Give this flag after those flags to also apply
149 When applying a patch, ignore additions made by the
150 patch. This can be used to extract the common part between
151 two files by first running 'diff' on them and applying
152 the result with this option, which would apply the
153 deletion part but not the addition part.
155 --allow-binary-replacement::
157 Historically we did not allow binary patch applied
158 without an explicit permission from the user, and this
159 flag was the way to do so. Currently we always allow binary
160 patch application, so this is a no-op.
162 --exclude=<path-pattern>::
163 Don't apply changes to files matching the given path pattern. This can
164 be useful when importing patchsets, where you want to exclude certain
165 files or directories.
167 --include=<path-pattern>::
168 Apply changes to files matching the given path pattern. This can
169 be useful when importing patchsets, where you want to include certain
170 files or directories.
172 When `--exclude` and `--include` patterns are used, they are examined in the
173 order they appear on the command line, and the first match determines if a
174 patch to each path is used. A patch to a path that does not match any
175 include/exclude pattern is used by default if there is no include pattern
176 on the command line, and ignored if there is any include pattern.
178 --ignore-space-change::
179 --ignore-whitespace::
180 When applying a patch, ignore changes in whitespace in context
182 Context lines will preserve their whitespace, and they will not
183 undergo whitespace fixing regardless of the value of the
184 `--whitespace` option. New lines will still be fixed, though.
186 --whitespace=<action>::
187 When applying a patch, detect a new or modified line that has
188 whitespace errors. What are considered whitespace errors is
189 controlled by `core.whitespace` configuration. By default,
190 trailing whitespaces (including lines that solely consist of
191 whitespaces) and a space character that is immediately followed
192 by a tab character inside the initial indent of the line are
193 considered whitespace errors.
195 By default, the command outputs warning messages but applies the patch.
196 When `git-apply` is used for statistics and not applying a
197 patch, it defaults to `nowarn`.
199 You can use different `<action>` values to control this
202 * `nowarn` turns off the trailing whitespace warning.
203 * `warn` outputs warnings for a few such errors, but applies the
204 patch as-is (default).
205 * `fix` outputs warnings for a few such errors, and applies the
206 patch after fixing them (`strip` is a synonym --- the tool
207 used to consider only trailing whitespace characters as errors, and the
208 fix involved 'stripping' them, but modern Gits do more).
209 * `error` outputs warnings for a few such errors, and refuses
211 * `error-all` is similar to `error` but shows all errors.
214 Under certain circumstances, some versions of 'diff' do not correctly
215 detect a missing new-line at the end of the file. As a result, patches
216 created by such 'diff' programs do not record incomplete lines
217 correctly. This option adds support for applying such patches by
218 working around this bug.
222 Report progress to stderr. By default, only a message about the
223 current patch being applied will be printed. This option will cause
224 additional information to be reported.
227 Do not trust the line counts in the hunk headers, but infer them
228 by inspecting the patch (e.g. after editing the patch without
229 adjusting the hunk headers appropriately).
232 Prepend <root> to all filenames. If a "-p" argument was also passed,
233 it is applied before prepending the new root.
235 For example, a patch that talks about updating `a/git-gui.sh` to `b/git-gui.sh`
236 can be applied to the file in the working tree `modules/git-gui/git-gui.sh` by
237 running `git apply --directory=modules/git-gui`.
242 apply.ignorewhitespace::
243 Set to 'change' if you want changes in whitespace to be ignored by default.
244 Set to one of: no, none, never, false if you want changes in
245 whitespace to be significant.
247 When no `--whitespace` flag is given from the command
248 line, this configuration item is used as the default.
252 If the patch contains any changes to submodules then 'git apply'
253 treats these changes as follows.
255 If `--index` is specified (explicitly or implicitly), then the submodule
256 commits must match the index exactly for the patch to apply. If any
257 of the submodules are checked-out, then these check-outs are completely
258 ignored, i.e., they are not required to be up-to-date or clean and they
261 If `--index` is not specified, then the submodule commits in the patch
262 are ignored and only the absence or presence of the corresponding
263 subdirectory is checked and (if possible) updated.
