This is the default.} 26endif::git-format-patch[] 27 28-U<n>:: 29--unified=<n>:: 30 Generate diffs with <n> lines of context instead of 31 the usual three. 32ifndef::git-format-patch[] 33 Implies `-p`. 34endif::git-format-patch[] 35 36ifndef::git-format-patch[] 37--raw:: 38 Generate the raw format. 39 {git-diff-core? This is the default.} 40endif::git-format-patch[] 41 42ifndef::git-format-patch[] 43--patch-with-raw:: 44 Synonym for `-p --raw`. 45endif::git-format-patch[] 46 47--patience:: 48 Generate a diff using the "patience diff" algorithm. 49 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. 55 56--numstat:: 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 61 `0 0`. 62 63--shortstat:: 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 66 lines. 67 68--dirstat[=limit]:: 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. 74 75--dirstat-by-file[=limit]:: 76 Same as `--dirstat`, but counts changed files instead of lines. 77 78--summary:: 79 Output a condensed summary of extended header information 80 such as creations, renames and mode changes. 81 82ifndef::git-format-patch[] 83--patch-with-stat:: 84 Synonym for `-p --stat`. 85endif::git-format-patch[] 86 87ifndef::git-format-patch[] 88 89-z:: 90ifdef::git-log[] 91 Separate the commits with NULs instead of with new newlines. 92+ 93Also, when `--raw` or `--numstat` has been given, do not munge 94pathnames and use NULs as output field terminators. 95endif::git-log[] 96ifndef::git-log[] 97 When `--raw`, `--numstat`, `--name-only` or `--name-status` has been 98 given, do not munge pathnames and use NULs as output field terminators. 99endif::git-log[] 100+ 101Without this option, each pathname output will have TAB, LF, double quotes, 102and backslash characters replaced with `\t`, `\n`, `\"`, and `\\`, 103respectively, and the pathname will be enclosed in double quotes if 104any of those replacements occurred. 105 106--name-only:: 107 Show only names of changed files. 108 109--name-status:: 110 Show only names and status of changed files. See the description 111 of the `--diff-filter` option on what the status letters mean. 112 113--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. 119 120--color:: 121 Show colored diff. 122 123--no-color:: 124 Turn off colored diff, even when the configuration file 125 gives the default to color output. 126 127--color-words[=<regex>]:: 128 Show colored word diff, i.e., color words which have changed. 129 By default, words are separated by whitespace. 130+ 131When a <regex> is specified, every non-overlapping match of the 132<regex> is considered a word. Anything between these matches is 133considered whitespace and ignored(!) for the purposes of finding 134differences. You may want to append `|[^[:space:]]` to your regular 135expression to make sure that it matches all non-whitespace characters. 136A match that contains a newline is silently truncated(!) at the 137newline. 138+ 139The regex can also be set via a diff driver or configuration option, see 140linkgit:gitattributes[1] or linkgit:git-config[1]. Giving it explicitly 141overrides any diff driver or configuration setting. Diff drivers 142override configuration settings. 143endif::git-format-patch[] 144 145--no-renames:: 146 Turn off rename detection, even when the configuration 147 file gives the default to do so. 148 149ifndef::git-format-patch[] 150--check:: 151 Warn if changes introduce trailing whitespace 152 or an indent that uses a space before a tab. Exits with 153 non-zero status if problems are found. Not compatible with 154 --exit-code. 155endif::git-format-patch[] 156 157--full-index:: 158 Instead of the first handful of characters, show the full 159 pre- and post-image blob object names on the "index" 160 line when generating patch format output. 161 162--binary:: 163 In addition to `--full-index`, output a binary diff that 164 can be applied with `git-apply`. 165 166--abbrev[=<n>]:: 167 Instead of showing the full 40-byte hexadecimal object 168 name in diff-raw format output and diff-tree header 169 lines, show only a partial prefix. This is 170 independent of the `--full-index` option above, which controls 171 the diff-patch output format. Non default number of 172 digits can be specified with `--abbrev=<n>`. 173 174-B:: 175 Break complete rewrite changes into pairs of delete and create. 176 177-M:: 178 Detect renames. 179 180-C:: 181 Detect copies as well as renames. See also `--find-copies-harder`. 182 183ifndef::git-format-patch[] 184--diff-filter=[ACDMRTUXB*]:: 185 Select only files that are Added (`A`), Copied (`C`), 186 Deleted (`D`), Modified (`M`), Renamed (`R`), have their 187 type (i.e. regular file, symlink, submodule, ...) changed (`T`), 188 are Unmerged (`U`), are 189 Unknown (`X`), or have had their pairing Broken (`B`). 190 Any combination of the filter characters may be used. 191 When `*` (All-or-none) is added to the combination, all 192 paths are selected if there is any file that matches 193 other criteria in the comparison; if there is no file 194 that matches other criteria, nothing is selected. 195endif::git-format-patch[] 196 197--find-copies-harder:: 198 For performance reasons, by default, `-C` option finds copies only 199 if the original file of the copy was modified in the same 200 changeset. This flag makes the command 201 inspect unmodified files as candidates for the source of 202 copy. This is a very expensive operation for large 203 projects, so use it with caution. Giving more than one 204 `-C` option has the same effect. 205 206-l<num>:: 207 The `-M` and `-C` options require O(n^2) processing time where n 208 is the number of potential rename/copy targets. This 209 option prevents rename/copy detection from running if 210 the number of rename/copy targets exceeds the specified 211 number. 212 213ifndef::git-format-patch[] 214-S<string>:: 215 Look for differences that introduce or remove an instance of 216 <string>. Note that this is different than the string simply 217 appearing in diff output; see the 'pickaxe' entry in 218 linkgit:gitdiffcore[7] for more details. 219 220--pickaxe-all:: 221 When `-S` finds a change, show all the changes in that 222 changeset, not just the files that contain the change 223 in <string>. 224 225--pickaxe-regex:: 226 Make the <string> not a plain string but an extended POSIX 227 regex to match. 228endif::git-format-patch[] 229 230-O<orderfile>:: 231 Output the patch in the order specified in the 232 <orderfile>, which has one shell glob pattern per line. 233 234ifndef::git-format-patch[] 235-R:: 236 Swap two inputs; that is, show differences from index or 237 on-disk file to tree contents. 238 239--relative[=<path>]:: 240 When run from a subdirectory of the project, it can be 241 told to exclude changes outside the directory and show 242 pathnames relative to it with this option. When you are 243 not in a subdirectory (e.g. in a bare repository), you 244 can name which subdirectory to make the output relative 245 to by giving a <path> as an argument. 246endif::git-format-patch[] 247 248-a:: 249--text:: 250 Treat all files as text. 251 252--ignore-space-at-eol:: 253 Ignore changes in whitespace at EOL. 254 255-b:: 256--ignore-space-change:: 257 Ignore changes in amount of whitespace. This ignores whitespace 258 at line end, and considers all other sequences of one or 259 more whitespace characters to be equivalent. 260 261-w:: 262--ignore-all-space:: 263 Ignore whitespace when comparing lines. This ignores 264 differences even if one line has whitespace where the other 265 line has none. 266 267--inter-hunk-context=<lines>:: 268 Show the context between diff hunks, up to the specified number 269 of lines, thereby fusing hunks that are close to each other. 270 271ifndef::git-format-patch[] 272--exit-code:: 273 Make the program exit with codes similar to diff(1). 274 That is, it exits with 1 if there were differences and 275 0 means no differences. 276 277--quiet:: 278 Disable all output of the program. Implies `--exit-code`. 279endif::git-format-patch[] 280 281--ext-diff:: 282 Allow an external diff helper to be executed. If you set an 283 external diff driver with linkgit:gitattributes[5], you need 284 to use this option with linkgit:git-log[1] and friends. 285 286--no-ext-diff:: 287 Disallow external diff drivers. 288 289--ignore-submodules:: 290 Ignore changes to submodules in the diff generation. 291 292--src-prefix=<prefix>:: 293 Show the given source prefix instead of "a/". 294 295--dst-prefix=<prefix>:: 296 Show the given destination prefix instead of "b/". 297 298--no-prefix:: 299 Do not show any source or destination prefix. 300 301For more detailed explanation on these common options, see also 302linkgit:gitdiffcore[7].
