42 | --stat[=width[,name-width]]:: |
43 | Generate a diffstat. You can override the default | |
44 | output width for 80-column terminal by "--stat=width". | |
45 | The width of the filename part can be controlled by | |
46 | giving another width to it separated by a comma. | |

48 | --numstat:: |
49 | Similar to \--stat, but shows number of added and | |
50 | deleted lines in decimal notation and pathname without | |
2f89543e JH |
51 | abbreviation, to make it more machine friendly. For |
52 | binary files, outputs two `-` instead of saying | |
53 | `0 0`. | |
74e2abe5 | 54 | |
ebd124c6 NP |
55 | --shortstat:: |
56 | Output only the last line of the --stat format containing total | |
57 | number of modified files, as well as number of added and deleted | |
58 | lines. | |
59 | ||
37152d83 | 60 | --dirstat[=limit]:: |
62e00b0a HO |
61 | Output the distribution of relative amount of changes (number of lines added or |
62 | removed) for each sub-directory. Directories with changes below | |
63 | a cut-off percent (3% by default) are not shown. The cut-off percent | |
64 | can be set with "--dirstat=limit". Changes in a child directory is not | |
65 | counted for the parent directory, unless "--cumulative" is used. | |
37152d83 | 66 | |
fd33777b HO |
67 | --dirstat-by-file[=limit]:: |
68 | Same as --dirstat, but counts changed files instead of lines. | |
69 | ||
4bbd261b SE |
70 | --summary:: |
71 | Output a condensed summary of extended header information | |
72 | such as creations, renames and mode changes. | |

29353273 | 77 | |
dda2d79a | 78 | -z:: |
654a7ccc JH |
79 | NUL-line termination on output. This affects the --raw |
80 | output field terminator. Also output from commands such | |
81 | as "git-log" will be delimited with NUL between commits. | |
dda2d79a JH |
82 | |
83 | --name-only:: | |
84 | Show only names of changed files. | |
85 | ||
946f5f7c | 86 | --name-status:: |
a6f47b2b MV |
87 | Show only names and status of changed files. See the description |
88 | of the `--diff-filter` option on what the status letters mean. | |
dda2d79a | 89 | |
b5376648 JH |
90 | --color:: |
91 | Show colored diff. | |
92 | ||
93 | --no-color:: | |
94 | Turn off colored diff, even when the configuration file | |
95 | gives the default to color output. | |
96 | ||
c4b252c3 TR |
97 | --color-words[=<regex>]:: |
98 | Show colored word diff, i.e., color words which have changed. | |
99 | By default, words are separated by whitespace. | |
2b6a5417 | 100 | + |
c4b252c3 TR |
101 | When a <regex> is specified, every non-overlapping match of the |
102 | <regex> is considered a word. Anything between these matches is | |
103 | considered whitespace and ignored(!) for the purposes of finding | |
104 | differences. You may want to append `|[^[:space:]]` to your regular | |
105 | expression to make sure that it matches all non-whitespace characters. | |
106 | A match that contains a newline is silently truncated(!) at the | |
107 | newline. | |
80c49c3d | 108 | + |
98a4d87b BSSJ |
109 | The regex can also be set via a diff driver or configuration option, see |
110 | linkgit:gitattributes[1] or linkgit:git-config[1]. Giving it explicitly | |
111 | overrides any diff driver or configuration setting. Diff drivers | |
112 | override configuration settings. | |
f59a59e2 | 113 | |
b5376648 JH |
114 | --no-renames:: |
115 | Turn off rename detection, even when the configuration | |
116 | file gives the default to do so. | |
117 | ||
16507fcf BL |
118 | --check:: |
119 | Warn if changes introduce trailing whitespace | |
62c64895 WC |
120 | or an indent that uses a space before a tab. Exits with |
121 | non-zero status if problems are found. Not compatible with | |
122 | --exit-code. | |
16507fcf | 123 | |
80b1e511 | 124 | --full-index:: |
6457e58c JM |
125 | Instead of the first handful of characters, show the full |
126 | pre- and post-image blob object names on the "index" | |
127 | line when generating patch format output. | |
b5376648 JH |
128 | |
129 | --binary:: | |
130 | In addition to --full-index, output "binary diff" that | |
131 | can be applied with "git apply". | |
80b1e511 | 132 | |
913419fc | 133 | --abbrev[=<n>]:: |
47dd0d59 JH |
134 | Instead of showing the full 40-byte hexadecimal object |
135 | name in diff-raw format output and diff-tree header | |
323b9db8 | 136 | lines, show only a partial prefix. This is |
913419fc JH |
137 | independent of --full-index option above, which controls |
138 | the diff-patch output format. Non default number of | |
139 | digits can be specified with --abbrev=<n>. | |
47dd0d59 | 140 | |
dda2d79a JH |
141 | -B:: |
142 | Break complete rewrite changes into pairs of delete and create. | |
143 | ||
144 | -M:: | |
145 | Detect renames. | |
146 | ||
147 | -C:: | |
ca6c0970 | 148 | Detect copies as well as renames. See also `--find-copies-harder`. |
dda2d79a | 149 | |
147cf317 JL |
150 | --diff-filter=[ACDMRTUXB*]:: |
151 | Select only files that are Added (`A`), Copied (`C`), | |
152 | Deleted (`D`), Modified (`M`), Renamed (`R`), have their | |
f07c3c53 JH |
153 | type (i.e. regular file, symlink, submodule, ...) changed (`T`), |
154 | are Unmerged (`U`), are | |
147cf317 JL |
155 | Unknown (`X`), or have had their pairing Broken (`B`). |
156 | Any combination of the filter characters may be used. | |
157 | When `*` (All-or-none) is added to the combination, all | |
158 | paths are selected if there is any file that matches | |
159 | other criteria in the comparison; if there is no file | |
160 | that matches other criteria, nothing is selected. | |
161 | ||
dda2d79a | 162 | --find-copies-harder:: |
ca6c0970 | 163 | For performance reasons, by default, `-C` option finds copies only |
a6080a0a | 164 | if the original file of the copy was modified in the same |
f73ae1fc | 165 | changeset. This flag makes the command |
dda2d79a JH |
166 | inspect unmodified files as candidates for the source of |
167 | copy. This is a very expensive operation for large | |
ca6c0970 JS |
168 | projects, so use it with caution. Giving more than one |
169 | `-C` option has the same effect. | |
dda2d79a | 170 | |
8082d8d3 JH |
171 | -l<num>:: |
172 | -M and -C options require O(n^2) processing time where n | |
f73ae1fc | 173 | is the number of potential rename/copy targets. This |
8082d8d3 | 174 | option prevents rename/copy detection from running if |
f73ae1fc | 175 | the number of rename/copy targets exceeds the specified |
8082d8d3 JH |
176 | number. |
177 | ||
dda2d79a | 178 | -S<string>:: |
821d56aa JK |
179 | Look for differences that introduce or remove an instance of |
180 | <string>. Note that this is different than the string simply | |
181 | appearing in diff output; see the 'pickaxe' entry in | |
182 | linkgit:gitdiffcore[7] for more details. | |
dda2d79a JH |
183 | |
184 | --pickaxe-all:: | |
185 | When -S finds a change, show all the changes in that | |
f73ae1fc | 186 | changeset, not just the files that contain the change |
dda2d79a JH |
187 | in <string>. |
188 | ||
d01d8c67 PB |
189 | --pickaxe-regex:: |
190 | Make the <string> not a plain string but an extended POSIX | |
191 | regex to match. | |
192 | ||
dda2d79a JH |
193 | -O<orderfile>:: |
194 | Output the patch in the order specified in the | |
195 | <orderfile>, which has one shell glob pattern per line. | |
196 | ||
197 | -R:: | |
5f3aa197 | 198 | Swap two inputs; that is, show differences from index or |
dda2d79a JH |
199 | on-disk file to tree contents. |
200 | ||
c0cb4a06 | 201 | --relative[=<path>]:: |
cd676a51 JH |
202 | When run from a subdirectory of the project, it can be |
203 | told to exclude changes outside the directory and show | |
c0cb4a06 JH |
204 | pathnames relative to it with this option. When you are |
205 | not in a subdirectory (e.g. in a bare repository), you | |
206 | can name which subdirectory to make the output relative | |
207 | to by giving a <path> as an argument. | |
cd676a51 | 208 | |
a9e67c8c | 209 | -a:: |
d507bb15 SF |
210 | --text:: |
211 | Treat all files as text. | |
212 | ||
a44a0c99 | 213 | --ignore-space-at-eol:: |
0ac7903e | 214 | Ignore changes in whitespace at EOL. |
a44a0c99 | 215 | |
a9e67c8c | 216 | -b:: |
8ebe185b | 217 | --ignore-space-change:: |
0ac7903e WC |
218 | Ignore changes in amount of whitespace. This ignores whitespace |
219 | at line end, and considers all other sequences of one or | |
220 | more whitespace characters to be equivalent. | |
8ebe185b | 221 | |
a9e67c8c | 222 | -w:: |
8ebe185b | 223 | --ignore-all-space:: |
0ac7903e WC |
224 | Ignore whitespace when comparing lines. This ignores |
225 | differences even if one line has whitespace where the other | |
8ebe185b JN |
226 | line has none. |
227 | ||
6d0e674a RS |
228 | --inter-hunk-context=<lines>:: |
229 | Show the context between diff hunks, up to the specified number | |
230 | of lines, thereby fusing hunks that are close to each other. | |
231 | ||
41bbf9d5 AR |
232 | --exit-code:: |
233 | Make the program exit with codes similar to diff(1). | |
234 | That is, it exits with 1 if there were differences and | |
235 | 0 means no differences. | |
236 | ||
2a18c266 AR |
237 | --quiet:: |
238 | Disable all output of the program. Implies --exit-code. | |
239 | ||
72909bef JS |
240 | --ext-diff:: |
241 | Allow an external diff helper to be executed. If you set an | |
5162e697 DM |
242 | external diff driver with linkgit:gitattributes[5], you need |
243 | to use this option with linkgit:git-log[1] and friends. | |
72909bef JS |
244 | |
245 | --no-ext-diff:: | |
246 | Disallow external diff drivers. | |
247 | ||
50fd9bd8 JS |
248 | --ignore-submodules:: |
249 | Ignore changes to submodules in the diff generation. | |
250 | ||
eab9a40b JS |
251 | --src-prefix=<prefix>:: |
252 | Show the given source prefix instead of "a/". | |
253 | ||
254 | --dst-prefix=<prefix>:: | |
255 | Show the given destination prefix instead of "b/". | |
256 | ||
257 | --no-prefix:: | |
258 | Do not show any source or destination prefix. | |
