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` or `--numstat` has been given, do not munge 98 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[=<when>]:: 121 Show colored diff. 122 The value must be always (the default), never, or auto. 123 124--no-color:: 125 Turn off colored diff, even when the configuration file 126 gives the default to color output. 127 Same as `--color=never`. 128 129--color-words[=<regex>]:: 130 Show colored word diff, i.e., color words which have changed. 131 By default, words are separated by whitespace. 132+ 133When a <regex> is specified, every non-overlapping match of the 134<regex> is considered a word. Anything between these matches is 135considered whitespace and ignored(!) for the purposes of finding 136differences. You may want to append `|[^[:space:]]` to your regular 137expression to make sure that it matches all non-whitespace characters. 138A match that contains a newline is silently truncated(!) at the 139newline. 140+ 141The regex can also be set via a diff driver or configuration option, see 142linkgit:gitattributes[1] or linkgit:git-config[1]. Giving it explicitly 143overrides any diff driver or configuration setting. Diff drivers 144override configuration settings. 145endif::git-format-patch[] 146 147--no-renames:: 148 Turn off rename detection, even when the configuration 149 file gives the default to do so. 150 151ifndef::git-format-patch[] 152--check:: 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 156 --exit-code. 157endif::git-format-patch[] 158 159--full-index:: 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. 163 164--binary:: 165 In addition to `--full-index`, output a binary diff that 166 can be applied with `git-apply`. 167 168--abbrev[=<n>]:: 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>`. 175 176-B:: 177 Break complete rewrite changes into pairs of delete and create. 178 179-M:: 180 Detect renames. 181 182-C:: 183 Detect copies as well as renames. See also `--find-copies-harder`. 184 185ifndef::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. 197endif::git-format-patch[] 198 199--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. 207 208-l<num>:: 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 213 number. 214 215ifndef::git-format-patch[] 216-S<string>:: 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. 221 222--pickaxe-all:: 223 When `-S` finds a change, show all the changes in that 224 changeset, not just the files that contain the change 225 in <string>. 226 227--pickaxe-regex:: 228 Make the <string> not a plain string but an extended POSIX 229 regex to match. 230endif::git-format-patch[] 231 232-O<orderfile>:: 233 Output the patch in the order specified in the 234 <orderfile>, which has one shell glob pattern per line. 235 236ifndef::git-format-patch[] 237-R:: 238 Swap two inputs; that is, show differences from index or 239 on-disk file to tree contents. 240 241--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. 248endif::git-format-patch[] 249 250-a:: 251--text:: 252 Treat all files as text. 253 254--ignore-space-at-eol:: 255 Ignore changes in whitespace at EOL. 256 257-b:: 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. 262 263-w:: 264--ignore-all-space:: 265 Ignore whitespace when comparing lines. This ignores 266 differences even if one line has whitespace where the other 267 line has none. 268 269--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. 272 273ifndef::git-format-patch[] 274--exit-code:: 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. 278 279--quiet:: 280 Disable all output of the program. Implies `--exit-code`. 281endif::git-format-patch[] 282 283--ext-diff:: 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. 287 288--no-ext-diff:: 289 Disallow external diff drivers. 290 291--ignore-submodules:: 292 Ignore changes to submodules in the diff generation. 293 294--src-prefix=<prefix>:: 295 Show the given source prefix instead of "a/". 296 297--dst-prefix=<prefix>:: 298 Show the given destination prefix instead of "b/". 299 300--no-prefix:: 301 Do not show any source or destination prefix. 302 303For more detailed explanation on these common options, see also 304linkgit:gitdiffcore[7].
