It uses the "patience 91diff" algorithm internally. 92 93--diff-algorithm={patience|minimal|histogram|myers}:: 94 Choose a diff algorithm. The variants are as follows: 95+ 96-- 97`default`, `myers`;; 98 The basic greedy diff algorithm. Currently, this is the default. 99`minimal`;; 100 Spend extra time to make sure the smallest possible diff is 101 produced. 102`patience`;; 103 Use "patience diff" algorithm when generating patches. 104`histogram`;; 105 This algorithm extends the patience algorithm to "support 106 low-occurrence common elements". 107-- 108+ 109For instance, if you configured diff.algorithm variable to a 110non-default value and want to use the default one, then you 111have to use `--diff-algorithm=default` option. 112 113--stat[=<width>[,<name-width>[,<count>]]]:: 114 Generate a diffstat. By default, as much space as necessary 115 will be used for the filename part, and the rest for the graph 116 part. Maximum width defaults to terminal width, or 80 columns 117 if not connected to a terminal, and can be overridden by 118 `<width>`. The width of the filename part can be limited by 119 giving another width `<name-width>` after a comma. The width 120 of the graph part can be limited by using 121 `--stat-graph-width=<width>` (affects all commands generating 122 a stat graph) or by setting `diff.statGraphWidth=<width>` 123 (does not affect `git format-patch`). 124 By giving a third parameter `<count>`, you can limit the 125 output to the first `<count>` lines, followed by `...` if 126 there are more. 127+ 128These parameters can also be set individually with `--stat-width=<width>`, 129`--stat-name-width=<name-width>` and `--stat-count=<count>`. 130 131--compact-summary:: 132 Output a condensed summary of extended header information such 133 as file creations or deletions ("new" or "gone", optionally "+l" 134 if it's a symlink) and mode changes ("+x" or "-x" for adding 135 or removing executable bit respectively) in diffstat. The 136 information is put betwen the filename part and the graph 137 part. Implies `--stat`. 138 139--numstat:: 140 Similar to `--stat`, but shows number of added and 141 deleted lines in decimal notation and pathname without 142 abbreviation, to make it more machine friendly. For 143 binary files, outputs two `-` instead of saying 144 `0 0`. 145 146--shortstat:: 147 Output only the last line of the `--stat` format containing total 148 number of modified files, as well as number of added and deleted 149 lines. 150 151--dirstat[=<param1,param2,...>]:: 152 Output the distribution of relative amount of changes for each 153 sub-directory. The behavior of `--dirstat` can be customized by 154 passing it a comma separated list of parameters. 155 The defaults are controlled by the `diff.dirstat` configuration 156 variable (see linkgit:git-config[1]). 157 The following parameters are available: 158+ 159-- 160`changes`;; 161 Compute the dirstat numbers by counting the lines that have been 162 removed from the source, or added to the destination. This ignores 163 the amount of pure code movements within a file. In other words, 164 rearranging lines in a file is not counted as much as other changes. 165 This is the default behavior when no parameter is given. 166`lines`;; 167 Compute the dirstat numbers by doing the regular line-based diff 168 analysis, and summing the removed/added line counts. (For binary 169 files, count 64-byte chunks instead, since binary files have no 170 natural concept of lines). This is a more expensive `--dirstat` 171 behavior than the `changes` behavior, but it does count rearranged 172 lines within a file as much as other changes. The resulting output 173 is consistent with what you get from the other `--*stat` options. 174`files`;; 175 Compute the dirstat numbers by counting the number of files changed. 176 Each changed file counts equally in the dirstat analysis. This is 177 the computationally cheapest `--dirstat` behavior, since it does 178 not have to look at the file contents at all. 179`cumulative`;; 180 Count changes in a child directory for the parent directory as well. 181 Note that when using `cumulative`, the sum of the percentages 182 reported may exceed 100%. The default (non-cumulative) behavior can 183 be specified with the `noncumulative` parameter. 184<limit>;; 185 An integer parameter specifies a cut-off percent (3% by default). 186 Directories contributing less than this percentage of the changes 187 are not shown in the output. 188-- 189+ 190Example: The following will count changed files, while ignoring 191directories with less than 10% of the total amount of changed files, 192and accumulating child directory counts in the parent directories: 193`--dirstat=files,10,cumulative`. 194 195--summary:: 196 Output a condensed summary of extended header information 197 such as creations, renames and mode changes. 198 199ifndef::git-format-patch[] 200--patch-with-stat:: 201 Synonym for `-p --stat`. 202endif::git-format-patch[] 203 204ifndef::git-format-patch[] 205 206-z:: 207ifdef::git-log[] 208 Separate the commits with NULs instead of with new newlines. 209+ 210Also, when `--raw` or `--numstat` has been given, do not munge 211pathnames and use NULs as output field terminators. 212endif::git-log[] 213ifndef::git-log[] 214 When `--raw`, `--numstat`, `--name-only` or `--name-status` has been 215 given, do not munge pathnames and use NULs as output field terminators. 216endif::git-log[] 217+ 218Without this option, pathnames with "unusual" characters are quoted as 219explained for the configuration variable `core.quotePath` (see 220linkgit:git-config[1]). 221 222--name-only:: 223 Show only names of changed files. 224 225--name-status:: 226 Show only names and status of changed files. See the description 227 of the `--diff-filter` option on what the status letters mean. 228 229--submodule[=<format>]:: 230 Specify how differences in submodules are shown. When specifying 231 `--submodule=short` the 'short' format is used. This format just 232 shows the names of the commits at the beginning and end of the range. 233 When `--submodule` or `--submodule=log` is specified, the 'log' 234 format is used. This format lists the commits in the range like 235 linkgit:git-submodule[1] `summary` does. When `--submodule=diff` 236 is specified, the 'diff' format is used. This format shows an 237 inline diff of the changes in the submodule contents between the 238 commit range. Defaults to `diff.submodule` or the 'short' format 239 if the config option is unset. 240 241--color[=<when>]:: 242 Show colored diff. 243 `--color` (i.e. without '=<when>') is the same as `--color=always`. 244 '<when>' can be one of `always`, `never`, or `auto`. 245ifdef::git-diff[] 246 It can be changed by the `color.ui` and `color.diff` 247 configuration settings. 248endif::git-diff[] 249 250--no-color:: 251 Turn off colored diff. 252ifdef::git-diff[] 253 This can be used to override configuration settings. 254endif::git-diff[] 255 It is the same as `--color=never`. 256 257--color-moved[=<mode>]:: 258 Moved lines of code are colored differently. 259ifdef::git-diff[] 260 It can be changed by the `diff.colorMoved` configuration setting. 261endif::git-diff[] 262 The <mode> defaults to 'no' if the option is not given 263 and to 'zebra' if the option with no mode is given. 264 The mode must be one of: 265+ 266-- 267no:: 268 Moved lines are not highlighted. 269default:: 270 Is a synonym for `zebra`. This may change to a more sensible mode 271 in the future. 272plain:: 273 Any line that is added in one location and was removed 274 in another location will be colored with 'color.diff.newMoved'. 275 Similarly 'color.diff.oldMoved' will be used for removed lines 276 that are added somewhere else in the diff. This mode picks up any 277 moved line, but it is not very useful in a review to determine 278 if a block of code was moved without permutation. 279zebra:: 280 Blocks of moved text of at least 20 alphanumeric characters 281 are detected greedily. The detected blocks are 282 painted using either the 'color.diff.{old,new}Moved' color or 283 'color.diff.{old,new}MovedAlternative'. The change between 284 the two colors indicates that a new block was detected. 285dimmed_zebra:: 286 Similar to 'zebra', but additional dimming of uninteresting parts 287 of moved code is performed. The bordering lines of two adjacent 288 blocks are considered interesting, the rest is uninteresting. 289-- 290 291--word-diff[=<mode>]:: 292 Show a word diff, using the <mode> to delimit changed words. 293 By default, words are delimited by whitespace; see 294 `--word-diff-regex` below. The <mode> defaults to 'plain', and 295 must be one of: 296+ 297-- 298color:: 299 Highlight changed words using only colors. Implies `--color`. 300plain:: 301 Show words as `[-removed-]` and `{+added+}`. Makes no 302 attempts to escape the delimiters if they appear in the input, 303 so the output may be ambiguous. 304porcelain:: 305 Use a special line-based format intended for script 306 consumption. Added/removed/unchanged runs are printed in the 307 usual unified diff format, starting with a `+`/`-`/` ` 308 character at the beginning of the line and extending to the 309 end of the line. Newlines in the input are represented by a 310 tilde `~` on a line of its own. 311none:: 312 Disable word diff again. 313-- 314+ 315Note that despite the name of the first mode, color is used to 316highlight the changed parts in all modes if enabled. 317 318--word-diff-regex=<regex>:: 319 Use <regex> to decide what a word is, instead of considering 320 runs of non-whitespace to be a word. Also implies 321 `--word-diff` unless it was already enabled. 322+ 323Every non-overlapping match of the 324<regex> is considered a word. Anything between these matches is 325considered whitespace and ignored(!) for the purposes of finding 326differences. You may want to append `|[^[:space:]]` to your regular 327expression to make sure that it matches all non-whitespace characters. 328A match that contains a newline is silently truncated(!) at the 329newline. 330+ 331For example, `--word-diff-regex=.` will treat each character as a word 332and, correspondingly, show differences character by character. 333+ 334The regex can also be set via a diff driver or configuration option, see 335linkgit:gitattributes[5] or linkgit:git-config[1]. Giving it explicitly 336overrides any diff driver or configuration setting. Diff drivers 337override configuration settings. 338 339--color-words[=<regex>]:: 340 Equivalent to `--word-diff=color` plus (if a regex was 341 specified) `--word-diff-regex=<regex>`. 342endif::git-format-patch[] 343 344--no-renames:: 345 Turn off rename detection, even when the configuration 346 file gives the default to do so. 347 348ifndef::git-format-patch[] 349--check:: 350 Warn if changes introduce conflict markers or whitespace errors. 351 What are considered whitespace errors is controlled by `core.whitespace` 352 configuration. By default, trailing whitespaces (including 353 lines that solely consist of whitespaces) and a space character 354 that is immediately followed by a tab character inside the 355 initial indent of the line are considered whitespace errors. 356 Exits with non-zero status if problems are found. Not compatible 357 with --exit-code. 358 359--ws-error-highlight=<kind>:: 360 Highlight whitespace errors in the `context`, `old` or `new` 361 lines of the diff. Multiple values are separated by comma, 362 `none` resets previous values, `default` reset the list to 363 `new` and `all` is a shorthand for `old,new,context`. When 364 this option is not given, and the configuration variable 365 `diff.wsErrorHighlight` is not set, only whitespace errors in 366 `new` lines are highlighted. The whitespace errors are colored 367 whith `color.diff.whitespace`. 368 369endif::git-format-patch[] 370 371--full-index:: 372 Instead of the first handful of characters, show the full 373 pre- and post-image blob object names on the "index" 374 line when generating patch format output. 375 376--binary:: 377 In addition to `--full-index`, output a binary diff that 378 can be applied with `git-apply`. 379 380--abbrev[=<n>]:: 381 Instead of showing the full 40-byte hexadecimal object 382 name in diff-raw format output and diff-tree header 383 lines, show only a partial prefix. This is 384 independent of the `--full-index` option above, which controls 385 the diff-patch output format. Non default number of 386 digits can be specified with `--abbrev=<n>`. 387 388-B[<n>][/<m>]:: 389--break-rewrites[=[<n>][/<m>]]:: 390 Break complete rewrite changes into pairs of delete and 391 create. This serves two purposes: 392+ 393It affects the way a change that amounts to a total rewrite of a file 394not as a series of deletion and insertion mixed together with a very 395few lines that happen to match textually as the context, but as a 396single deletion of everything old followed by a single insertion of 397everything new, and the number `m` controls this aspect of the -B 398option (defaults to 60%). `-B/70%` specifies that less than 30% of the 399original should remain in the result for Git to consider it a total 400rewrite (i.e. otherwise the resulting patch will be a series of 401deletion and insertion mixed together with context lines). 402+ 403When used with -M, a totally-rewritten file is also considered as the 404source of a rename (usually -M only considers a file that disappeared 405as the source of a rename), and the number `n` controls this aspect of 406the -B option (defaults to 50%). `-B20%` specifies that a change with 407addition and deletion compared to 20% or more of the file's size are 408eligible for being picked up as a possible source of a rename to 409another file. 410 411-M[<n>]:: 412--find-renames[=<n>]:: 413ifndef::git-log[] 414 Detect renames. 415endif::git-log[] 416ifdef::git-log[] 417 If generating diffs, detect and report renames for each commit. 418 For following files across renames while traversing history, see 419 `--follow`. 420endif::git-log[] 421 If `n` is specified, it is a threshold on the similarity 422 index (i.e. amount of addition/deletions compared to the 423 file's size). For example, `-M90%` means Git should consider a 424 delete/add pair to be a rename if more than 90% of the file 425 hasn't changed. Without a `%` sign, the number is to be read as 426 a fraction, with a decimal point before it. I.e., `-M5` becomes 427 0.5, and is thus the same as `-M50%`. Similarly, `-M05` is 428 the same as `-M5%`. To limit detection to exact renames, use 429 `-M100%`. The default similarity index is 50%. 430 431-C[<n>]:: 432--find-copies[=<n>]:: 433 Detect copies as well as renames. See also `--find-copies-harder`. 434 If `n` is specified, it has the same meaning as for `-M<n>`. 435 436--find-copies-harder:: 437 For performance reasons, by default, `-C` option finds copies only 438 if the original file of the copy was modified in the same 439 changeset. This flag makes the command 440 inspect unmodified files as candidates for the source of 441 copy. This is a very expensive operation for large 442 projects, so use it with caution. Giving more than one 443 `-C` option has the same effect. 444 445-D:: 446--irreversible-delete:: 447 Omit the preimage for deletes, i.e. print only the header but not 448 the diff between the preimage and `/dev/null`. The resulting patch 449 is not meant to be applied with `patch` or `git apply`; this is 450 solely for people who want to just concentrate on reviewing the 451 text after the change. In addition, the output obviously lacks 452 enough information to apply such a patch in reverse, even manually, 453 hence the name of the option. 454+ 455When used together with `-B`, omit also the preimage in the deletion part 456of a delete/create pair. 457 458-l<num>:: 459 The `-M` and `-C` options require O(n^2) processing time where n 460 is the number of potential rename/copy targets. This 461 option prevents rename/copy detection from running if 462 the number of rename/copy targets exceeds the specified 463 number. 464 465ifndef::git-format-patch[] 466--diff-filter=[(A|C|D|M|R|T|U|X|B)...[*]]:: 467 Select only files that are Added (`A`), Copied (`C`), 468 Deleted (`D`), Modified (`M`), Renamed (`R`), have their 469 type (i.e. regular file, symlink, submodule, ...) changed (`T`), 470 are Unmerged (`U`), are 471 Unknown (`X`), or have had their pairing Broken (`B`). 472 Any combination of the filter characters (including none) can be used. 473 When `*` (All-or-none) is added to the combination, all 474 paths are selected if there is any file that matches 475 other criteria in the comparison; if there is no file 476 that matches other criteria, nothing is selected. 477+ 478Also, these upper-case letters can be downcased to exclude. E.g. 479`--diff-filter=ad` excludes added and deleted paths. 480+ 481Note that not all diffs can feature all types. For instance, diffs 482from the index to the working tree can never have Added entries 483(because the set of paths included in the diff is limited by what is in 484the index). Similarly, copied and renamed entries cannot appear if 485detection for those types is disabled. 486 487-S<string>:: 488 Look for differences that change the number of occurrences of 489 the specified string (i.e. addition/deletion) in a file. 490 Intended for the scripter's use. 491+ 492It is useful when you're looking for an exact block of code (like a 493struct), and want to know the history of that block since it first 494came into being: use the feature iteratively to feed the interesting 495block in the preimage back into `-S`, and keep going until you get the 496very first version of the block. 497 498-G<regex>:: 499 Look for differences whose patch text contains added/removed 500 lines that match <regex>. 501+ 502To illustrate the difference between `-S<regex> --pickaxe-regex` and 503`-G<regex>`, consider a commit with the following diff in the same 504file: 505+ 506---- 507+ return !regexec(regexp, two->ptr, 1, ®match, 0); 508... 509- hit = !regexec(regexp, mf2.ptr, 1, ®match, 0); 510---- 511+ 512While `git log -G"regexec\(regexp"` will show this commit, `git log 513-S"regexec\(regexp" --pickaxe-regex` will not (because the number of 514occurrences of that string did not change). 515+ 516See the 'pickaxe' entry in linkgit:gitdiffcore[7] for more 517information. 518 519--find-object=<object-id>:: 520 Look for differences that change the number of occurrences of 521 the specified object. Similar to `-S`, just the argument is different 522 in that it doesn't search for a specific string but for a specific 523 object id. 524+ 525The object can be a blob or a submodule commit. It implies the `-t` option in 526`git-log` to also find trees. 527 528--pickaxe-all:: 529 When `-S` or `-G` finds a change, show all the changes in that 530 changeset, not just the files that contain the change 531 in <string>. 532 533--pickaxe-regex:: 534 Treat the <string> given to `-S` as an extended POSIX regular 535 expression to match. 536 537endif::git-format-patch[] 538 539-O<orderfile>:: 540 Control the order in which files appear in the output. 541 This overrides the `diff.orderFile` configuration variable 542 (see linkgit:git-config[1]). To cancel `diff.orderFile`, 543 use `-O/dev/null`. 544+ 545The output order is determined by the order of glob patterns in 546<orderfile>. 547All files with pathnames that match the first pattern are output 548first, all files with pathnames that match the second pattern (but not 549the first) are output next, and so on. 550All files with pathnames that do not match any pattern are output 551last, as if there was an implicit match-all pattern at the end of the 552file. 553If multiple pathnames have the same rank (they match the same pattern 554but no earlier patterns), their output order relative to each other is 555the normal order. 556+ 557<orderfile> is parsed as follows: 558+ 559-- 560 - Blank lines are ignored, so they can be used as separators for 561 readability. 562 563 - Lines starting with a hash ("`#`") are ignored, so they can be used 564 for comments. Add a backslash ("`\`") to the beginning of the 565 pattern if it starts with a hash. 566 567 - Each other line contains a single pattern. 568-- 569+ 570Patterns have the same syntax and semantics as patterns used for 571fnmantch(3) without the FNM_PATHNAME flag, except a pathname also 572matches a pattern if removing any number of the final pathname 573components matches the pattern. For example, the pattern "`foo*bar`" 574matches "`fooasdfbar`" and "`foo/bar/baz/asdf`" but not "`foobarx`". 575 576ifndef::git-format-patch[] 577-R:: 578 Swap two inputs; that is, show differences from index or 579 on-disk file to tree contents. 580 581--relative[=<path>]:: 582 When run from a subdirectory of the project, it can be 583 told to exclude changes outside the directory and show 584 pathnames relative to it with this option.

Implies `--exit-code`. 634endif::git-log[] 635endif::git-format-patch[] 636 637--ext-diff:: 638 Allow an external diff helper to be executed. If you set an 639 external diff driver with linkgit:gitattributes[5], you need 640 to use this option with linkgit:git-log[1] and friends. 641 642--no-ext-diff:: 643 Disallow external diff drivers. 644 645--textconv:: 646--no-textconv:: 647 Allow (or disallow) external text conversion filters to be run 648 when comparing binary files. See linkgit:gitattributes[5] for 649 details. Because textconv filters are typically a one-way 650 conversion, the resulting diff is suitable for human 651 consumption, but cannot be applied. For this reason, textconv 652 filters are enabled by default only for linkgit:git-diff[1] and 653 linkgit:git-log[1], but not for linkgit:git-format-patch[1] or 654 diff plumbing commands. 655 656--ignore-submodules[=<when>]:: 657 Ignore changes to submodules in the diff generation. <when> can be 658 either "none", "untracked", "dirty" or "all", which is the default. 659 Using "none" will consider the submodule modified when it either contains 660 untracked or modified files or its HEAD differs from the commit recorded 661 in the superproject and can be used to override any settings of the 662 'ignore' option in linkgit:git-config[1] or linkgit:gitmodules[5]. When 663 "untracked" is used submodules are not considered dirty when they only 664 contain untracked content (but they are still scanned for modified 665 content). Using "dirty" ignores all changes to the work tree of submodules, 666 only changes to the commits stored in the superproject are shown (this was 667 the behavior until 1.7.0). Using "all" hides all changes to submodules. 668 669--src-prefix=<prefix>:: 670 Show the given source prefix instead of "a/". 671 672--dst-prefix=<prefix>:: 673 Show the given destination prefix instead of "b/". 674 675--no-prefix:: 676 Do not show any source or destination prefix. 677 678--line-prefix=<prefix>:: 679 Prepend an additional prefix to every line of output. 680 681--ita-invisible-in-index:: 682 By default entries added by "git add -N" appear as an existing 683 empty file in "git diff" and a new file in "git diff --cached". 684 This option makes the entry appear as a new file in "git diff" 685 and non-existent in "git diff --cached". This option could be 686 reverted with `--ita-visible-in-index`. Both options are 687 experimental and could be removed in future. 688 689For more detailed explanation on these common options, see also 690linkgit:gitdiffcore[7].
