18 Generate plain patches without any diffstats.
19 endif::git-format-patch[]
21 ifndef::git-format-patch[]
24 Generate patch (see section on generating patches).
25 {git-diff? This is the default.}
26 endif::git-format-patch[]
30 Generate diffs with <n> lines of context instead of
32 ifndef::git-format-patch[]
34 endif::git-format-patch[]
36 ifndef::git-format-patch[]
38 Generate the raw format.
39 {git-diff-core? This is the default.}
40 endif::git-format-patch[]
42 ifndef::git-format-patch[]
44 Synonym for `-p --raw`.
45 endif::git-format-patch[]
48 Generate a diff using the "patience diff" algorithm.
50 --stat[=width[,name-width]]::
51 Generate a diffstat. You can override the default
52 output width for 80-column terminal by `--stat=width`.
53 The width of the filename part can be controlled by
54 giving another width to it separated by a comma.
57 Similar to `\--stat`, but shows number of added and
58 deleted lines in decimal notation and pathname without
59 abbreviation, to make it more machine friendly. For
60 binary files, outputs two `-` instead of saying
64 Output only the last line of the `--stat` format containing total
65 number of modified files, as well as number of added and deleted
69 Output the distribution of relative amount of changes (number of lines added or
70 removed) for each sub-directory. Directories with changes below
71 a cut-off percent (3% by default) are not shown. The cut-off percent
72 can be set with `--dirstat=limit`. Changes in a child directory is not
73 counted for the parent directory, unless `--cumulative` is used.
75 --dirstat-by-file[=limit]::
76 Same as `--dirstat`, but counts changed files instead of lines.
79 Output a condensed summary of extended header information
80 such as creations, renames and mode changes.
82 ifndef::git-format-patch[]
84 Synonym for `-p --stat`.
85 endif::git-format-patch[]
87 ifndef::git-format-patch[]
91 Separate the commits with NULs instead of with new newlines.
93 Also, when `--raw` or `--numstat` has been given, do not munge
94 pathnames and use NULs as output field terminators.
97 When `--raw` or `--numstat` has been given, do not munge
98 pathnames and use NULs as output field terminators.
101 Without this option, each pathname output will have TAB, LF, double quotes,
102 and backslash characters replaced with `\t`, `\n`, `\"`, and `\\`,
103 respectively, and the pathname will be enclosed in double quotes if
104 any of those replacements occurred.
107 Show only names of changed files.
110 Show only names and status of changed files. See the description
111 of the `--diff-filter` option on what the status letters mean.
113 --submodule[=<format>]::
114 Chose the output format for submodule differences. <format> can be one of
115 'short' and 'log'. 'short' just shows pairs of commit names, this format
116 is used when this option is not given. 'log' is the default value for this
117 option and lists the commits in that commit range like the 'summary'
118 option of linkgit:git-submodule[1] does.
124 Turn off colored diff, even when the configuration file
125 gives the default to color output.
127 --color-words[=<regex>]::
128 Show colored word diff, i.e., color words which have changed.
129 By default, words are separated by whitespace.
131 When a <regex> is specified, every non-overlapping match of the
132 <regex> is considered a word. Anything between these matches is
133 considered whitespace and ignored(!) for the purposes of finding
134 differences. You may want to append `|[^[:space:]]` to your regular
135 expression to make sure that it matches all non-whitespace characters.
136 A match that contains a newline is silently truncated(!) at the
139 The regex can also be set via a diff driver or configuration option, see
140 linkgit:gitattributes[1] or linkgit:git-config[1]. Giving it explicitly
141 overrides any diff driver or configuration setting. Diff drivers
142 override configuration settings.
143 endif::git-format-patch[]
146 Turn off rename detection, even when the configuration
147 file gives the default to do so.
149 ifndef::git-format-patch[]
151 Warn if changes introduce trailing whitespace
152 or an indent that uses a space before a tab. Exits with
153 non-zero status if problems are found. Not compatible with
155 endif::git-format-patch[]
158 Instead of the first handful of characters, show the full
159 pre- and post-image blob object names on the "index"
160 line when generating patch format output.
163 In addition to `--full-index`, output a binary diff that
164 can be applied with `git-apply`.
167 Instead of showing the full 40-byte hexadecimal object
168 name in diff-raw format output and diff-tree header
169 lines, show only a partial prefix. This is
170 independent of the `--full-index` option above, which controls
171 the diff-patch output format. Non default number of
172 digits can be specified with `--abbrev=<n>`.
175 Break complete rewrite changes into pairs of delete and create.
181 Detect copies as well as renames. See also `--find-copies-harder`.
183 ifndef::git-format-patch[]
184 --diff-filter=[ACDMRTUXB*]::
185 Select only files that are Added (`A`), Copied (`C`),
186 Deleted (`D`), Modified (`M`), Renamed (`R`), have their
187 type (i.e. regular file, symlink, submodule, ...) changed (`T`),
188 are Unmerged (`U`), are
189 Unknown (`X`), or have had their pairing Broken (`B`).
190 Any combination of the filter characters may be used.
191 When `*` (All-or-none) is added to the combination, all
192 paths are selected if there is any file that matches
193 other criteria in the comparison; if there is no file
194 that matches other criteria, nothing is selected.
195 endif::git-format-patch[]
197 --find-copies-harder::
198 For performance reasons, by default, `-C` option finds copies only
199 if the original file of the copy was modified in the same
200 changeset. This flag makes the command
201 inspect unmodified files as candidates for the source of
202 copy. This is a very expensive operation for large
203 projects, so use it with caution. Giving more than one
204 `-C` option has the same effect.
207 The `-M` and `-C` options require O(n^2) processing time where n
208 is the number of potential rename/copy targets. This
209 option prevents rename/copy detection from running if
210 the number of rename/copy targets exceeds the specified
213 ifndef::git-format-patch[]
215 Look for differences that introduce or remove an instance of
216 <string>. Note that this is different than the string simply
217 appearing in diff output; see the 'pickaxe' entry in
218 linkgit:gitdiffcore[7] for more details.
221 When `-S` finds a change, show all the changes in that
222 changeset, not just the files that contain the change
226 Make the <string> not a plain string but an extended POSIX
228 endif::git-format-patch[]
231 Output the patch in the order specified in the
232 <orderfile>, which has one shell glob pattern per line.
234 ifndef::git-format-patch[]
236 Swap two inputs; that is, show differences from index or
237 on-disk file to tree contents.
239 --relative[=<path>]::
240 When run from a subdirectory of the project, it can be
241 told to exclude changes outside the directory and show
242 pathnames relative to it with this option. When you are
243 not in a subdirectory (e.g. in a bare repository), you
244 can name which subdirectory to make the output relative
245 to by giving a <path> as an argument.
246 endif::git-format-patch[]
250 Treat all files as text.
252 --ignore-space-at-eol::
253 Ignore changes in whitespace at EOL.
256 --ignore-space-change::
257 Ignore changes in amount of whitespace. This ignores whitespace
258 at line end, and considers all other sequences of one or
259 more whitespace characters to be equivalent.
263 Ignore whitespace when comparing lines. This ignores
264 differences even if one line has whitespace where the other
267 --inter-hunk-context=<lines>::
268 Show the context between diff hunks, up to the specified number
269 of lines, thereby fusing hunks that are close to each other.
271 ifndef::git-format-patch[]
273 Make the program exit with codes similar to diff(1).
274 That is, it exits with 1 if there were differences and
275 0 means no differences.
278 Disable all output of the program. Implies `--exit-code`.
279 endif::git-format-patch[]
282 Allow an external diff helper to be executed. If you set an
283 external diff driver with linkgit:gitattributes[5], you need
284 to use this option with linkgit:git-log[1] and friends.
287 Disallow external diff drivers.
289 --ignore-submodules::
290 Ignore changes to submodules in the diff generation.
292 --src-prefix=<prefix>::
293 Show the given source prefix instead of "a/".
295 --dst-prefix=<prefix>::
296 Show the given destination prefix instead of "b/".
299 Do not show any source or destination prefix.
