7 ifndef::git-format-patch[]
13 endif::git-format-patch[]
15 ifdef::git-format-patch[]
17 Generate patches without diffstat.
18 endif::git-format-patch[]
20 ifndef::git-format-patch[]
22 Generate patch (see section on generating patches).
23 {git-diff? This is the default.}
24 endif::git-format-patch[]
30 Shorthand for "--unified=<n>".
33 Generate diffs with <n> lines of context instead of
34 the usual three. Implies "-p".
37 Generate the raw format.
38 {git-diff-core? This is the default.}
41 Synonym for "-p --raw".
43 --stat[=width[,name-width]]::
44 Generate a diffstat. You can override the default
45 output width for 80-column terminal by "--stat=width".
46 The width of the filename part can be controlled by
47 giving another width to it separated by a comma.
50 Similar to \--stat, but shows number of added and
51 deleted lines in decimal notation and pathname without
52 abbreviation, to make it more machine friendly. For
53 binary files, outputs two `-` instead of saying
57 Output only the last line of the --stat format containing total
58 number of modified files, as well as number of added and deleted
62 Output only the sub-directories that are impacted by a diff,
63 and to what degree they are impacted. You can override the
64 default cut-off in percent (3) by "--dirstat=limit". If you
65 want to enable "cumulative" directory statistics, you can use
66 the "--cumulative" flag, which adds up percentages recursively
67 even when they have been already reported for a sub-directory.
70 Output a condensed summary of extended header information
71 such as creations, renames and mode changes.
74 Synonym for "-p --stat".
75 {git-format-patch? This is the default.}
78 NUL-line termination on output. This affects the --raw
79 output field terminator. Also output from commands such
80 as "git-log" will be delimited with NUL between commits.
83 Show only names of changed files.
86 Show only names and status of changed files.
92 Turn off colored diff, even when the configuration file
93 gives the default to color output.
96 Show colored word diff, i.e. color words which have changed.
99 Turn off rename detection, even when the configuration
100 file gives the default to do so.
103 Warn if changes introduce trailing whitespace
104 or an indent that uses a space before a tab. Exits with
105 non-zero status if problems are found. Not compatible with
109 Instead of the first handful characters, show full
110 object name of pre- and post-image blob on the "index"
111 line when generating a patch format output.
114 In addition to --full-index, output "binary diff" that
115 can be applied with "git apply".
118 Instead of showing the full 40-byte hexadecimal object
119 name in diff-raw format output and diff-tree header
120 lines, show only handful hexdigits prefix. This is
121 independent of --full-index option above, which controls
122 the diff-patch output format. Non default number of
123 digits can be specified with --abbrev=<n>.
126 Break complete rewrite changes into pairs of delete and create.
132 Detect copies as well as renames. See also `--find-copies-harder`.
134 --diff-filter=[ACDMRTUXB*]::
135 Select only files that are Added (`A`), Copied (`C`),
136 Deleted (`D`), Modified (`M`), Renamed (`R`), have their
137 type (mode) changed (`T`), are Unmerged (`U`), are
138 Unknown (`X`), or have had their pairing Broken (`B`).
139 Any combination of the filter characters may be used.
140 When `*` (All-or-none) is added to the combination, all
141 paths are selected if there is any file that matches
142 other criteria in the comparison; if there is no file
143 that matches other criteria, nothing is selected.
145 --find-copies-harder::
146 For performance reasons, by default, `-C` option finds copies only
147 if the original file of the copy was modified in the same
148 changeset. This flag makes the command
149 inspect unmodified files as candidates for the source of
150 copy. This is a very expensive operation for large
151 projects, so use it with caution. Giving more than one
152 `-C` option has the same effect.
155 -M and -C options require O(n^2) processing time where n
156 is the number of potential rename/copy targets. This
157 option prevents rename/copy detection from running if
158 the number of rename/copy targets exceeds the specified
162 Look for differences that contain the change in <string>.
165 When -S finds a change, show all the changes in that
166 changeset, not just the files that contain the change
170 Make the <string> not a plain string but an extended POSIX
174 Output the patch in the order specified in the
175 <orderfile>, which has one shell glob pattern per line.
178 Swap two inputs; that is, show differences from index or
179 on-disk file to tree contents.
181 --relative[=<path>]::
182 When run from a subdirectory of the project, it can be
183 told to exclude changes outside the directory and show
184 pathnames relative to it with this option. When you are
185 not in a subdirectory (e.g. in a bare repository), you
186 can name which subdirectory to make the output relative
187 to by giving a <path> as an argument.
190 Treat all files as text.
193 Shorthand for "--text".
195 --ignore-space-at-eol::
196 Ignore changes in whitespace at EOL.
198 --ignore-space-change::
199 Ignore changes in amount of whitespace. This ignores whitespace
200 at line end, and considers all other sequences of one or
201 more whitespace characters to be equivalent.
204 Shorthand for "--ignore-space-change".
207 Ignore whitespace when comparing lines. This ignores
208 differences even if one line has whitespace where the other
212 Shorthand for "--ignore-all-space".
215 Make the program exit with codes similar to diff(1).
216 That is, it exits with 1 if there were differences and
217 0 means no differences.
220 Disable all output of the program. Implies --exit-code.
223 Allow an external diff helper to be executed. If you set an
224 external diff driver with linkgit:gitattributes[5], you need
225 to use this option with linkgit:git-log[1] and friends.
228 Disallow external diff drivers.
230 --src-prefix=<prefix>::
231 Show the given source prefix instead of "a/".
233 --dst-prefix=<prefix>::
234 Show the given destination prefix instead of "b/".
237 Do not show any source or destination prefix.
