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.
122 The value must be always (the default), never, or auto.
125 Turn off colored diff, even when the configuration file
126 gives the default to color output.
127 Same as `--color=never`.
129 --color-words[=<regex>]::
130 Show colored word diff, i.e., color words which have changed.
131 By default, words are separated by whitespace.
133 When a <regex> is specified, every non-overlapping match of the
134 <regex> is considered a word. Anything between these matches is
135 considered whitespace and ignored(!) for the purposes of finding
136 differences. You may want to append `|[^[:space:]]` to your regular
137 expression to make sure that it matches all non-whitespace characters.
138 A match that contains a newline is silently truncated(!) at the
141 The regex can also be set via a diff driver or configuration option, see
142 linkgit:gitattributes[1] or linkgit:git-config[1]. Giving it explicitly
143 overrides any diff driver or configuration setting. Diff drivers
144 override configuration settings.
145 endif::git-format-patch[]
148 Turn off rename detection, even when the configuration
149 file gives the default to do so.
151 ifndef::git-format-patch[]
153 Warn if changes introduce trailing whitespace
154 or an indent that uses a space before a tab. Exits with
155 non-zero status if problems are found. Not compatible with
157 endif::git-format-patch[]
160 Instead of the first handful of characters, show the full
161 pre- and post-image blob object names on the "index"
162 line when generating patch format output.
165 In addition to `--full-index`, output a binary diff that
166 can be applied with `git-apply`.
169 Instead of showing the full 40-byte hexadecimal object
170 name in diff-raw format output and diff-tree header
171 lines, show only a partial prefix. This is
172 independent of the `--full-index` option above, which controls
173 the diff-patch output format. Non default number of
174 digits can be specified with `--abbrev=<n>`.
177 Break complete rewrite changes into pairs of delete and create.
183 Detect copies as well as renames. See also `--find-copies-harder`.
185 ifndef::git-format-patch[]
186 --diff-filter=[ACDMRTUXB*]::
187 Select only files that are Added (`A`), Copied (`C`),
188 Deleted (`D`), Modified (`M`), Renamed (`R`), have their
189 type (i.e. regular file, symlink, submodule, ...) changed (`T`),
190 are Unmerged (`U`), are
191 Unknown (`X`), or have had their pairing Broken (`B`).
192 Any combination of the filter characters may be used.
193 When `*` (All-or-none) is added to the combination, all
194 paths are selected if there is any file that matches
195 other criteria in the comparison; if there is no file
196 that matches other criteria, nothing is selected.
197 endif::git-format-patch[]
199 --find-copies-harder::
200 For performance reasons, by default, `-C` option finds copies only
201 if the original file of the copy was modified in the same
202 changeset. This flag makes the command
203 inspect unmodified files as candidates for the source of
204 copy. This is a very expensive operation for large
205 projects, so use it with caution. Giving more than one
206 `-C` option has the same effect.
209 The `-M` and `-C` options require O(n^2) processing time where n
210 is the number of potential rename/copy targets. This
211 option prevents rename/copy detection from running if
212 the number of rename/copy targets exceeds the specified
215 ifndef::git-format-patch[]
217 Look for differences that introduce or remove an instance of
218 <string>. Note that this is different than the string simply
219 appearing in diff output; see the 'pickaxe' entry in
220 linkgit:gitdiffcore[7] for more details.
223 When `-S` finds a change, show all the changes in that
224 changeset, not just the files that contain the change
228 Make the <string> not a plain string but an extended POSIX
230 endif::git-format-patch[]
233 Output the patch in the order specified in the
234 <orderfile>, which has one shell glob pattern per line.
236 ifndef::git-format-patch[]
238 Swap two inputs; that is, show differences from index or
239 on-disk file to tree contents.
241 --relative[=<path>]::
242 When run from a subdirectory of the project, it can be
243 told to exclude changes outside the directory and show
244 pathnames relative to it with this option. When you are
245 not in a subdirectory (e.g. in a bare repository), you
246 can name which subdirectory to make the output relative
247 to by giving a <path> as an argument.
248 endif::git-format-patch[]
252 Treat all files as text.
254 --ignore-space-at-eol::
255 Ignore changes in whitespace at EOL.
258 --ignore-space-change::
259 Ignore changes in amount of whitespace. This ignores whitespace
260 at line end, and considers all other sequences of one or
261 more whitespace characters to be equivalent.
265 Ignore whitespace when comparing lines. This ignores
266 differences even if one line has whitespace where the other
269 --inter-hunk-context=<lines>::
270 Show the context between diff hunks, up to the specified number
271 of lines, thereby fusing hunks that are close to each other.
273 ifndef::git-format-patch[]
275 Make the program exit with codes similar to diff(1).
276 That is, it exits with 1 if there were differences and
277 0 means no differences.
280 Disable all output of the program. Implies `--exit-code`.
281 endif::git-format-patch[]
284 Allow an external diff helper to be executed. If you set an
285 external diff driver with linkgit:gitattributes[5], you need
286 to use this option with linkgit:git-log[1] and friends.
289 Disallow external diff drivers.
291 --ignore-submodules::
292 Ignore changes to submodules in the diff generation.
294 --src-prefix=<prefix>::
295 Show the given source prefix instead of "a/".
297 --dst-prefix=<prefix>::
298 Show the given destination prefix instead of "b/".
301 Do not show any source or destination prefix.
