17 Generate plain patches without any diffstats.
18 endif::git-format-patch[]
20 ifndef::git-format-patch[]
23 Generate patch (see section on generating patches).
24 {git-diff? This is the default.}
25 endif::git-format-patch[]
29 Generate diffs with <n> lines of context instead of
31 ifndef::git-format-patch[]
33 endif::git-format-patch[]
35 ifndef::git-format-patch[]
37 Generate the raw format.
38 {git-diff-core? This is the default.}
39 endif::git-format-patch[]

43 Synonym for "-p --raw".
44 endif::git-format-patch[]
47 Generate a diff using the "patience diff" algorithm.
49 --stat[=width[,name-width]]::
50 Generate a diffstat. You can override the default
51 output width for 80-column terminal by "--stat=width".
52 The width of the filename part can be controlled by
53 giving another width to it separated by a comma.
56 Similar to \--stat, but shows number of added and
57 deleted lines in decimal notation and pathname without
58 abbreviation, to make it more machine friendly. For
59 binary files, outputs two `-` instead of saying
63 Output only the last line of the --stat format containing total
64 number of modified files, as well as number of added and deleted
68 Output the distribution of relative amount of changes (number of lines added or
69 removed) for each sub-directory. Directories with changes below
70 a cut-off percent (3% by default) are not shown. The cut-off percent
71 can be set with "--dirstat=limit". Changes in a child directory is not
72 counted for the parent directory, unless "--cumulative" is used.
74 --dirstat-by-file[=limit]::
75 Same as --dirstat, but counts changed files instead of lines.
78 Output a condensed summary of extended header information
79 such as creations, renames and mode changes.
81 ifndef::git-format-patch[]
83 Synonym for "-p --stat".
84 endif::git-format-patch[]
86 ifndef::git-format-patch[]
88 NUL-line termination on output. This affects the --raw
89 output field terminator. Also output from commands such
90 as "git-log" will be delimited with NUL between commits.
93 Show only names of changed files.
96 Show only names and status of changed files. See the description
97 of the `--diff-filter` option on what the status letters mean.
103 Turn off colored diff, even when the configuration file
104 gives the default to color output.
106 --color-words[=<regex>]::
107 Show colored word diff, i.e., color words which have changed.
108 By default, words are separated by whitespace.
110 When a <regex> is specified, every non-overlapping match of the
111 <regex> is considered a word. Anything between these matches is
112 considered whitespace and ignored(!) for the purposes of finding
113 differences. You may want to append `|[^[:space:]]` to your regular
114 expression to make sure that it matches all non-whitespace characters.
115 A match that contains a newline is silently truncated(!) at the
118 The regex can also be set via a diff driver or configuration option, see
119 linkgit:gitattributes[1] or linkgit:git-config[1]. Giving it explicitly
120 overrides any diff driver or configuration setting. Diff drivers
121 override configuration settings.
122 endif::git-format-patch[]
125 Turn off rename detection, even when the configuration
126 file gives the default to do so.
128 ifndef::git-format-patch[]
130 Warn if changes introduce trailing whitespace
131 or an indent that uses a space before a tab. Exits with
132 non-zero status if problems are found. Not compatible with
134 endif::git-format-patch[]
137 Instead of the first handful of characters, show the full
138 pre- and post-image blob object names on the "index"
139 line when generating patch format output.
142 In addition to --full-index, output "binary diff" that
143 can be applied with "git apply".
146 Instead of showing the full 40-byte hexadecimal object
147 name in diff-raw format output and diff-tree header
148 lines, show only a partial prefix. This is
149 independent of --full-index option above, which controls
150 the diff-patch output format. Non default number of
151 digits can be specified with --abbrev=<n>.
154 Break complete rewrite changes into pairs of delete and create.
160 Detect copies as well as renames. See also `--find-copies-harder`.
162 ifndef::git-format-patch[]
163 --diff-filter=[ACDMRTUXB*]::
164 Select only files that are Added (`A`), Copied (`C`),
165 Deleted (`D`), Modified (`M`), Renamed (`R`), have their
166 type (i.e. regular file, symlink, submodule, ...) changed (`T`),
167 are Unmerged (`U`), are
168 Unknown (`X`), or have had their pairing Broken (`B`).
169 Any combination of the filter characters may be used.
170 When `*` (All-or-none) is added to the combination, all
171 paths are selected if there is any file that matches
172 other criteria in the comparison; if there is no file
173 that matches other criteria, nothing is selected.
174 endif::git-format-patch[]
176 --find-copies-harder::
177 For performance reasons, by default, `-C` option finds copies only
178 if the original file of the copy was modified in the same
179 changeset. This flag makes the command
180 inspect unmodified files as candidates for the source of
181 copy. This is a very expensive operation for large
182 projects, so use it with caution. Giving more than one
183 `-C` option has the same effect.
186 -M and -C options require O(n^2) processing time where n
187 is the number of potential rename/copy targets. This
188 option prevents rename/copy detection from running if
189 the number of rename/copy targets exceeds the specified
192 ifndef::git-format-patch[]
194 Look for differences that introduce or remove an instance of
195 <string>. Note that this is different than the string simply
196 appearing in diff output; see the 'pickaxe' entry in
197 linkgit:gitdiffcore[7] for more details.
200 When -S finds a change, show all the changes in that
201 changeset, not just the files that contain the change
205 Make the <string> not a plain string but an extended POSIX
207 endif::git-format-patch[]
210 Output the patch in the order specified in the
211 <orderfile>, which has one shell glob pattern per line.
213 ifndef::git-format-patch[]
215 Swap two inputs; that is, show differences from index or
216 on-disk file to tree contents.
218 --relative[=<path>]::
219 When run from a subdirectory of the project, it can be
220 told to exclude changes outside the directory and show
221 pathnames relative to it with this option. When you are
222 not in a subdirectory (e.g. in a bare repository), you
223 can name which subdirectory to make the output relative
224 to by giving a <path> as an argument.
225 endif::git-format-patch[]
229 Treat all files as text.
231 --ignore-space-at-eol::
232 Ignore changes in whitespace at EOL.
235 --ignore-space-change::
236 Ignore changes in amount of whitespace. This ignores whitespace
237 at line end, and considers all other sequences of one or
238 more whitespace characters to be equivalent.
242 Ignore whitespace when comparing lines. This ignores
243 differences even if one line has whitespace where the other
246 --inter-hunk-context=<lines>::
247 Show the context between diff hunks, up to the specified number
248 of lines, thereby fusing hunks that are close to each other.
250 ifndef::git-format-patch[]
252 Make the program exit with codes similar to diff(1).
253 That is, it exits with 1 if there were differences and
254 0 means no differences.
257 Disable all output of the program. Implies --exit-code.
258 endif::git-format-patch[]
261 Allow an external diff helper to be executed. If you set an
262 external diff driver with linkgit:gitattributes[5], you need
263 to use this option with linkgit:git-log[1] and friends.
266 Disallow external diff drivers.
268 --ignore-submodules::
269 Ignore changes to submodules in the diff generation.
271 --src-prefix=<prefix>::
272 Show the given source prefix instead of "a/".
274 --dst-prefix=<prefix>::
275 Show the given destination prefix instead of "b/".
278 Do not show any source or destination prefix.
