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[]
89 NUL-line termination on output. This affects the `--raw`
90 output field terminator. Also output from commands such
91 as `git-log` will be delimited with NUL between commits.
94 Show only names of changed files.
97 Show only names and status of changed files. See the description
98 of the `--diff-filter` option on what the status letters mean.
100 --submodule[=<format>]::
101 Chose the output format for submodule differences. <format> can be one of
102 'short' and 'log'. 'short' just shows pairs of commit names, this format
103 is used when this option is not given. 'log' is the default value for this
104 option and lists the commits in that commit range like the 'summary'
105 option of linkgit:git-submodule[1] does.
111 Turn off colored diff, even when the configuration file
112 gives the default to color output.
114 --color-words[=<regex>]::
115 Show colored word diff, i.e., color words which have changed.
116 By default, words are separated by whitespace.
118 When a <regex> is specified, every non-overlapping match of the
119 <regex> is considered a word. Anything between these matches is
120 considered whitespace and ignored(!) for the purposes of finding
121 differences. You may want to append `|[^[:space:]]` to your regular
122 expression to make sure that it matches all non-whitespace characters.
123 A match that contains a newline is silently truncated(!) at the
126 The regex can also be set via a diff driver or configuration option, see
127 linkgit:gitattributes[1] or linkgit:git-config[1]. Giving it explicitly
128 overrides any diff driver or configuration setting. Diff drivers
129 override configuration settings.
130 endif::git-format-patch[]
133 Turn off rename detection, even when the configuration
134 file gives the default to do so.
136 ifndef::git-format-patch[]
138 Warn if changes introduce trailing whitespace
139 or an indent that uses a space before a tab. Exits with
140 non-zero status if problems are found. Not compatible with
142 endif::git-format-patch[]
145 Instead of the first handful of characters, show the full
146 pre- and post-image blob object names on the "index"
147 line when generating patch format output.
150 In addition to `--full-index`, output a binary diff that
151 can be applied with `git-apply`.
154 Instead of showing the full 40-byte hexadecimal object
155 name in diff-raw format output and diff-tree header
156 lines, show only a partial prefix. This is
157 independent of the `--full-index` option above, which controls
158 the diff-patch output format. Non default number of
159 digits can be specified with `--abbrev=<n>`.
162 Break complete rewrite changes into pairs of delete and create.
168 Detect copies as well as renames. See also `--find-copies-harder`.
170 ifndef::git-format-patch[]
171 --diff-filter=[ACDMRTUXB*]::
172 Select only files that are Added (`A`), Copied (`C`),
173 Deleted (`D`), Modified (`M`), Renamed (`R`), have their
174 type (i.e. regular file, symlink, submodule, ...) changed (`T`),
175 are Unmerged (`U`), are
176 Unknown (`X`), or have had their pairing Broken (`B`).
177 Any combination of the filter characters may be used.
178 When `*` (All-or-none) is added to the combination, all
179 paths are selected if there is any file that matches
180 other criteria in the comparison; if there is no file
181 that matches other criteria, nothing is selected.
182 endif::git-format-patch[]
184 --find-copies-harder::
185 For performance reasons, by default, `-C` option finds copies only
186 if the original file of the copy was modified in the same
187 changeset. This flag makes the command
188 inspect unmodified files as candidates for the source of
189 copy. This is a very expensive operation for large
190 projects, so use it with caution. Giving more than one
191 `-C` option has the same effect.
194 The `-M` and `-C` options require O(n^2) processing time where n
195 is the number of potential rename/copy targets. This
196 option prevents rename/copy detection from running if
197 the number of rename/copy targets exceeds the specified
200 ifndef::git-format-patch[]
202 Look for differences that introduce or remove an instance of
203 <string>. Note that this is different than the string simply
204 appearing in diff output; see the 'pickaxe' entry in
205 linkgit:gitdiffcore[7] for more details.
208 When `-S` finds a change, show all the changes in that
209 changeset, not just the files that contain the change
213 Make the <string> not a plain string but an extended POSIX
215 endif::git-format-patch[]
218 Output the patch in the order specified in the
219 <orderfile>, which has one shell glob pattern per line.
221 ifndef::git-format-patch[]
223 Swap two inputs; that is, show differences from index or
224 on-disk file to tree contents.
226 --relative[=<path>]::
227 When run from a subdirectory of the project, it can be
228 told to exclude changes outside the directory and show
229 pathnames relative to it with this option. When you are
230 not in a subdirectory (e.g. in a bare repository), you
231 can name which subdirectory to make the output relative
232 to by giving a <path> as an argument.
233 endif::git-format-patch[]
237 Treat all files as text.
239 --ignore-space-at-eol::
240 Ignore changes in whitespace at EOL.
243 --ignore-space-change::
244 Ignore changes in amount of whitespace. This ignores whitespace
245 at line end, and considers all other sequences of one or
246 more whitespace characters to be equivalent.
250 Ignore whitespace when comparing lines. This ignores
251 differences even if one line has whitespace where the other
254 --inter-hunk-context=<lines>::
255 Show the context between diff hunks, up to the specified number
256 of lines, thereby fusing hunks that are close to each other.
258 ifndef::git-format-patch[]
260 Make the program exit with codes similar to diff(1).
261 That is, it exits with 1 if there were differences and
262 0 means no differences.
265 Disable all output of the program. Implies `--exit-code`.
266 endif::git-format-patch[]
269 Allow an external diff helper to be executed. If you set an
270 external diff driver with linkgit:gitattributes[5], you need
271 to use this option with linkgit:git-log[1] and friends.
274 Disallow external diff drivers.
276 --ignore-submodules::
277 Ignore changes to submodules in the diff generation.
279 --src-prefix=<prefix>::
280 Show the given source prefix instead of "a/".
282 --dst-prefix=<prefix>::
283 Show the given destination prefix instead of "b/".
286 Do not show any source or destination prefix.
