   1Commit Limiting
   2~~~~~~~~~~~~~~~
   3
   4Besides specifying a range of commits that should be listed using the
   5special notations explained in the description, additional commit
   6limiting may be applied.
   7
   8Using more options generally further limits the output (e.g.
   9`--since=<date1>` limits to commits newer than `<date1>`, and using it
  10with `--grep=<pattern>` further limits to commits whose log message
  11has a line that matches `<pattern>`), unless otherwise noted.
  12
  13Note that these are applied before commit
  14ordering and formatting options, such as `--reverse`.
  15
  16--
  17
  18-<number>::
  19-n <number>::
  20--max-count=<number>::
  21        Limit the number of commits to output.
  22
  23--skip=<number>::
  24        Skip 'number' commits before starting to show the commit output.
  25
  26--since=<date>::
  27--after=<date>::
  28        Show commits more recent than a specific date.
  29
  30--until=<date>::
  31--before=<date>::
  32        Show commits older than a specific date.
  33
  34ifdef::git-rev-list[]
  35--max-age=<timestamp>::
  36--min-age=<timestamp>::
  37        Limit the commits output to specified time range.
  38endif::git-rev-list[]
  39
  40--author=<pattern>::
  41--committer=<pattern>::
  42        Limit the commits output to ones with author/committer
  43        header lines that match the specified pattern (regular
  44        expression).  With more than one `--author=<pattern>`,
  45        commits whose author matches any of the given patterns are
  46        chosen (similarly for multiple `--committer=<pattern>`).
  47
  48--grep-reflog=<pattern>::
  49        Limit the commits output to ones with reflog entries that
  50        match the specified pattern (regular expression). With
  51        more than one `--grep-reflog`, commits whose reflog message
  52        matches any of the given patterns are chosen.  It is an
  53        error to use this option unless `--walk-reflogs` is in use.
  54
  55--grep=<pattern>::
  56        Limit the commits output to ones with log message that
  57        matches the specified pattern (regular expression).  With
  58        more than one `--grep=<pattern>`, commits whose message
  59        matches any of the given patterns are chosen (but see
  60        `--all-match`).
  61+
  62When `--show-notes` is in effect, the message from the notes as
  63if it is part of the log message.
  64
  65--all-match::
  66        Limit the commits output to ones that match all given `--grep`,
  67        instead of ones that match at least one.
  68
  69-i::
  70--regexp-ignore-case::
  71        Match the regular expression limiting patterns without regard to letter
  72        case.
  73
  74--basic-regexp::
  75        Consider the limiting patterns to be basic regular expressions;
  76        this is the default.
  77
  78-E::
  79--extended-regexp::
  80        Consider the limiting patterns to be extended regular expressions
  81        instead of the default basic regular expressions.
  82
  83-F::
  84--fixed-strings::
  85        Consider the limiting patterns to be fixed strings (don't interpret
  86        pattern as a regular expression).
  87
  88--perl-regexp::
  89        Consider the limiting patterns to be Perl-compatible regular expressions.
  90        Requires libpcre to be compiled in.
  91
  92--remove-empty::
  93        Stop when a given path disappears from the tree.
  94
  95--merges::
  96        Print only merge commits. This is exactly the same as `--min-parents=2`.
  97
  98--no-merges::
  99        Do not print commits with more than one parent. This is
 100        exactly the same as `--max-parents=1`.
 101
 102--min-parents=<number>::
 103--max-parents=<number>::
 104--no-min-parents::
 105--no-max-parents::
 106        Show only commits which have at least (or at most) that many parent
 107        commits. In particular, `--max-parents=1` is the same as `--no-merges`,
 108        `--min-parents=2` is the same as `--merges`.  `--max-parents=0`
 109        gives all root commits and `--min-parents=3` all octopus merges.
 110+
 111`--no-min-parents` and `--no-max-parents` reset these limits (to no limit)
 112again.  Equivalent forms are `--min-parents=0` (any commit has 0 or more
 113parents) and `--max-parents=-1` (negative numbers denote no upper limit).
 114
 115--first-parent::
 116        Follow only the first parent commit upon seeing a merge
 117        commit.  This option can give a better overview when
 118        viewing the evolution of a particular topic branch,
 119        because merges into a topic branch tend to be only about
 120        adjusting to updated upstream from time to time, and
 121        this option allows you to ignore the individual commits
 122        brought in to your history by such a merge.
 123
 124--not::
 125        Reverses the meaning of the '{caret}' prefix (or lack thereof)
 126        for all following revision specifiers, up to the next `--not`.
 127
 128--all::
 129        Pretend as if all the refs in `refs/` are listed on the
 130        command line as '<commit>'.
 131
 132--branches[=<pattern>]::
 133        Pretend as if all the refs in `refs/heads` are listed
 134        on the command line as '<commit>'. If '<pattern>' is given, limit
 135        branches to ones matching given shell glob. If pattern lacks '?',
 136        '{asterisk}', or '[', '/{asterisk}' at the end is implied.
 137
 138--tags[=<pattern>]::
 139        Pretend as if all the refs in `refs/tags` are listed
 140        on the command line as '<commit>'. If '<pattern>' is given, limit
 141        tags to ones matching given shell glob. If pattern lacks '?', '{asterisk}',
 142        or '[', '/{asterisk}' at the end is implied.
 143
 144--remotes[=<pattern>]::
 145        Pretend as if all the refs in `refs/remotes` are listed
 146        on the command line as '<commit>'. If '<pattern>' is given, limit
 147        remote-tracking branches to ones matching given shell glob.
 148        If pattern lacks '?', '{asterisk}', or '[', '/{asterisk}' at the end is implied.
 149
 150--glob=<glob-pattern>::
 151        Pretend as if all the refs matching shell glob '<glob-pattern>'
 152        are listed on the command line as '<commit>'. Leading 'refs/',
 153        is automatically prepended if missing. If pattern lacks '?', '{asterisk}',
 154        or '[', '/{asterisk}' at the end is implied.
 155
 156--exclude=<glob-pattern>::
 157
 158        Do not include refs matching '<glob-pattern>' that the next `--all`,
 159        `--branches`, `--tags`, `--remotes`, or `--glob` would otherwise
 160        consider. Repetitions of this option accumulate exclusion patterns
 161        up to the next `--all`, `--branches`, `--tags`, `--remotes`, or
 162        `--glob` option (other options or arguments do not clear
 163        accumlated patterns).
 164+
 165The patterns given should not begin with `refs/heads`, `refs/tags`, or
 166`refs/remotes` when applied to `--branches`, `--tags`, or `--remotes`,
 167respectively, and they must begin with `refs/` when applied to `--glob`
 168or `--all`. If a trailing '/{asterisk}' is intended, it must be given
 169explicitly.
 170
 171--ignore-missing::
 172        Upon seeing an invalid object name in the input, pretend as if
 173        the bad input was not given.
 174
 175ifndef::git-rev-list[]
 176--bisect::
 177        Pretend as if the bad bisection ref `refs/bisect/bad`
 178        was listed and as if it was followed by `--not` and the good
 179        bisection refs `refs/bisect/good-*` on the command
 180        line.
 181endif::git-rev-list[]
 182
 183--stdin::
 184        In addition to the '<commit>' listed on the command
 185        line, read them from the standard input. If a '--' separator is
 186        seen, stop reading commits and start reading paths to limit the
 187        result.
 188
 189ifdef::git-rev-list[]
 190--quiet::
 191        Don't print anything to standard output.  This form
 192        is primarily meant to allow the caller to
 193        test the exit status to see if a range of objects is fully
 194        connected (or not).  It is faster than redirecting stdout
 195        to `/dev/null` as the output does not have to be formatted.
 196endif::git-rev-list[]
 197
 198--cherry-mark::
 199        Like `--cherry-pick` (see below) but mark equivalent commits
 200        with `=` rather than omitting them, and inequivalent ones with `+`.
 201
 202--cherry-pick::
 203        Omit any commit that introduces the same change as
 204        another commit on the ``other side'' when the set of
 205        commits are limited with symmetric difference.
 206+
 207For example, if you have two branches, `A` and `B`, a usual way
 208to list all commits on only one side of them is with
 209`--left-right` (see the example below in the description of
 210the `--left-right` option). However, it shows the commits that were
 211cherry-picked from the other branch (for example, ``3rd on b'' may be
 212cherry-picked from branch A). With this option, such pairs of commits are
 213excluded from the output.
 214
 215--left-only::
 216--right-only::
 217        List only commits on the respective side of a symmetric range,
 218        i.e. only those which would be marked `<` resp. `>` by
 219        `--left-right`.
 220+
 221For example, `--cherry-pick --right-only A...B` omits those
 222commits from `B` which are in `A` or are patch-equivalent to a commit in
 223`A`. In other words, this lists the `+` commits from `git cherry A B`.
 224More precisely, `--cherry-pick --right-only --no-merges` gives the exact
 225list.
 226
 227--cherry::
 228        A synonym for `--right-only --cherry-mark --no-merges`; useful to
 229        limit the output to the commits on our side and mark those that
 230        have been applied to the other side of a forked history with
 231        `git log --cherry upstream...mybranch`, similar to
 232        `git cherry upstream mybranch`.
 233
 234-g::
 235--walk-reflogs::
 236        Instead of walking the commit ancestry chain, walk
 237        reflog entries from the most recent one to older ones.
 238        When this option is used you cannot specify commits to
 239        exclude (that is, '{caret}commit', 'commit1..commit2',
 240        and 'commit1\...commit2' notations cannot be used).
 241+
 242With `--pretty` format other than `oneline` (for obvious reasons),
 243this causes the output to have two extra lines of information
 244taken from the reflog.  By default, 'commit@\{Nth}' notation is
 245used in the output.  When the starting commit is specified as
 246'commit@\{now}', output also uses 'commit@\{timestamp}' notation
 247instead.  Under `--pretty=oneline`, the commit message is
 248prefixed with this information on the same line.
 249This option cannot be combined with `--reverse`.
 250See also linkgit:git-reflog[1].
 251
 252--merge::
 253        After a failed merge, show refs that touch files having a
 254        conflict and don't exist on all heads to merge.
 255
 256--boundary::
 257        Output excluded boundary commits. Boundary commits are
 258        prefixed with `-`.
 259
 260ifdef::git-rev-list[]
 261--use-bitmap-index::
 262
 263        Try to speed up the traversal using the pack bitmap index (if
 264        one is available). Note that when traversing with `--objects`,
 265        trees and blobs will not have their associated path printed.

 270History Simplification
 271~~~~~~~~~~~~~~~~~~~~~~
 272
 273Sometimes you are only interested in parts of the history, for example the
 274commits modifying a particular <path>. But there are two parts of
 275'History Simplification', one part is selecting the commits and the other
 276is how to do it, as there are various strategies to simplify the history.
 277
 278The following options select the commits to be shown:
 279
 280<paths>::
 281        Commits modifying the given <paths> are selected.
 282
 283--simplify-by-decoration::
 284        Commits that are referred by some branch or tag are selected.
 285
 286Note that extra commits can be shown to give a meaningful history.
 287
 288The following options affect the way the simplification is performed:
 289
 290Default mode::
 291        Simplifies the history to the simplest history explaining the
 292        final state of the tree. Simplest because it prunes some side
 293        branches if the end result is the same (i.e. merging branches
 294        with the same content)
 295
 296--full-history::
 297        Same as the default mode, but does not prune some history.
 298
 299--dense::
 300        Only the selected commits are shown, plus some to have a
 301        meaningful history.
 302
 303--sparse::
 304        All commits in the simplified history are shown.
 305
 306--simplify-merges::
 307        Additional option to `--full-history` to remove some needless
 308        merges from the resulting history, as there are no selected
 309        commits contributing to this merge.
 310
 311--ancestry-path::
 312        When given a range of commits to display (e.g. 'commit1..commit2'
 313        or 'commit2 {caret}commit1'), only display commits that exist
 314        directly on the ancestry chain between the 'commit1' and
 315        'commit2', i.e. commits that are both descendants of 'commit1',
 316        and ancestors of 'commit2'.
 317
 318A more detailed explanation follows.
 319
 320Suppose you specified `foo` as the <paths>.  We shall call commits
 321that modify `foo` !TREESAME, and the rest TREESAME.  (In a diff
 322filtered for `foo`, they look different and equal, respectively.)
 323
 324In the following, we will always refer to the same example history to
 325illustrate the differences between simplification settings.  We assume
 326that you are filtering for a file `foo` in this commit graph:
 327-----------------------------------------------------------------------
 328          .-A---M---N---O---P---Q
 329         /     /   /   /   /   /
 330        I     B   C   D   E   Y
 331         \   /   /   /   /   /
 332          `-------------'   X
 333-----------------------------------------------------------------------
 334The horizontal line of history A---Q is taken to be the first parent of
 335each merge.  The commits are:
 336
 337* `I` is the initial commit, in which `foo` exists with contents
 338  ``asdf'', and a file `quux` exists with contents ``quux''. Initial
 339  commits are compared to an empty tree, so `I` is !TREESAME.
 340
 341* In `A`, `foo` contains just ``foo''.
 342
 343* `B` contains the same change as `A`.  Its merge `M` is trivial and
 344  hence TREESAME to all parents.
 345
 346* `C` does not change `foo`, but its merge `N` changes it to ``foobar'',
 347  so it is not TREESAME to any parent.
 348
 349* `D` sets `foo` to ``baz''. Its merge `O` combines the strings from
 350  `N` and `D` to ``foobarbaz''; i.e., it is not TREESAME to any parent.
 351
 352* `E` changes `quux` to ``xyzzy'', and its merge `P` combines the
 353  strings to ``quux xyzzy''. `P` is TREESAME to `O`, but not to `E`.
 354
 355* `X` is an independent root commit that added a new file `side`, and `Y`
 356  modified it. `Y` is TREESAME to `X`. Its merge `Q` added `side` to `P`, and
 357  `Q` is TREESAME to `P`, but not to `Y`.
 358
 359`rev-list` walks backwards through history, including or excluding
 360commits based on whether `--full-history` and/or parent rewriting
 361(via `--parents` or `--children`) are used. The following settings
 362are available.
 363
 364Default mode::
 365        Commits are included if they are not TREESAME to any parent
 366        (though this can be changed, see `--sparse` below).  If the
 367        commit was a merge, and it was TREESAME to one parent, follow
 368        only that parent.  (Even if there are several TREESAME
 369        parents, follow only one of them.)  Otherwise, follow all
 370        parents.
 371+
 372This results in:
 373+
 374-----------------------------------------------------------------------
 375          .-A---N---O
 376         /     /   /
 377        I---------D
 378-----------------------------------------------------------------------
 379+
 380Note how the rule to only follow the TREESAME parent, if one is
 381available, removed `B` from consideration entirely.  `C` was
 382considered via `N`, but is TREESAME.  Root commits are compared to an
 383empty tree, so `I` is !TREESAME.
 384+
 385Parent/child relations are only visible with `--parents`, but that does
 386not affect the commits selected in default mode, so we have shown the
 387parent lines.
 388
 389--full-history without parent rewriting::
 390        This mode differs from the default in one point: always follow
 391        all parents of a merge, even if it is TREESAME to one of them.
 392        Even if more than one side of the merge has commits that are
 393        included, this does not imply that the merge itself is!  In
 394        the example, we get
 395+
 396-----------------------------------------------------------------------
 397        I  A  B  N  D  O  P  Q
 398-----------------------------------------------------------------------
 399+
 400`M` was excluded because it is TREESAME to both parents.  `E`,
 401`C` and `B` were all walked, but only `B` was !TREESAME, so the others
 402do not appear.
 403+
 404Note that without parent rewriting, it is not really possible to talk
 405about the parent/child relationships between the commits, so we show
 406them disconnected.
 407
 408--full-history with parent rewriting::
 409        Ordinary commits are only included if they are !TREESAME
 410        (though this can be changed, see `--sparse` below).
 411+
 412Merges are always included.  However, their parent list is rewritten:
 413Along each parent, prune away commits that are not included
 414themselves.  This results in
 415+
 416-----------------------------------------------------------------------
 417          .-A---M---N---O---P---Q
 418         /     /   /   /   /
 419        I     B   /   D   /
 420         \   /   /   /   /
 421          `-------------'
 422-----------------------------------------------------------------------
 423+
 424Compare to `--full-history` without rewriting above.  Note that `E`
 425was pruned away because it is TREESAME, but the parent list of P was
 426rewritten to contain `E`'s parent `I`.  The same happened for `C` and
 427`N`, and `X`, `Y` and `Q`.
 428
 429In addition to the above settings, you can change whether TREESAME
 430affects inclusion:
 431
 432--dense::
 433        Commits that are walked are included if they are not TREESAME
 434        to any parent.
 435
 436--sparse::
 437        All commits that are walked are included.
 438+
 439Note that without `--full-history`, this still simplifies merges: if
 440one of the parents is TREESAME, we follow only that one, so the other
 441sides of the merge are never walked.
 442
 443--simplify-merges::
 444        First, build a history graph in the same way that
 445        `--full-history` with parent rewriting does (see above).
 446+
 447Then simplify each commit `C` to its replacement `C'` in the final
 448history according to the following rules:
 449+
 450--
 451* Set `C'` to `C`.
 452+
 453* Replace each parent `P` of `C'` with its simplification `P'`.  In
 454  the process, drop parents that are ancestors of other parents or that are
 455  root commits TREESAME to an empty tree, and remove duplicates, but take care
 456  to never drop all parents that we are TREESAME to.
 457+
 458* If after this parent rewriting, `C'` is a root or merge commit (has
 459  zero or >1 parents), a boundary commit, or !TREESAME, it remains.
 460  Otherwise, it is replaced with its only parent.
 461--
 462+
 463The effect of this is best shown by way of comparing to
 464`--full-history` with parent rewriting.  The example turns into:
 465+
 466-----------------------------------------------------------------------
 467          .-A---M---N---O
 468         /     /       /

 470         \   /       /
 471          `---------'
 472-----------------------------------------------------------------------
 473+
 474Note the major differences in `N`, `P`, and `Q` over `--full-history`:
 475+
 476--
 477* `N`'s parent list had `I` removed, because it is an ancestor of the
 478  other parent `M`.  Still, `N` remained because it is !TREESAME.
 479+
 480* `P`'s parent list similarly had `I` removed.  `P` was then
 481  removed completely, because it had one parent and is TREESAME.
 482+
 483* `Q`'s parent list had `Y` simplified to `X`. `X` was then removed, because it
 484  was a TREESAME root. `Q` was then removed completely, because it had one
 485  parent and is TREESAME.
 486--
 487
 488Finally, there is a fifth simplification mode available:
 489
 490--ancestry-path::
 491        Limit the displayed commits to those directly on the ancestry
 492        chain between the ``from'' and ``to'' commits in the given commit
 493        range. I.e. only display commits that are ancestor of the ``to''
 494        commit and descendants of the ``from'' commit.
 495+
 496As an example use case, consider the following commit history:
 497+
 498-----------------------------------------------------------------------
 499            D---E-------F
 500           /     \       \
 501          B---C---G---H---I---J
 502         /                     \
 503        A-------K---------------L--M
 504-----------------------------------------------------------------------
 505+
 506A regular 'D..M' computes the set of commits that are ancestors of `M`,
 507but excludes the ones that are ancestors of `D`. This is useful to see
 508what happened to the history leading to `M` since `D`, in the sense
 509that ``what does `M` have that did not exist in `D`''. The result in this
 510example would be all the commits, except `A` and `B` (and `D` itself,
 511of course).
 512+
 513When we want to find out what commits in `M` are contaminated with the
 514bug introduced by `D` and need fixing, however, we might want to view
 515only the subset of 'D..M' that are actually descendants of `D`, i.e.
 516excluding `C` and `K`. This is exactly what the `--ancestry-path`
 517option does. Applied to the 'D..M' range, it results in:
 518+
 519-----------------------------------------------------------------------
 520                E-------F
 521                 \       \
 522                  G---H---I---J
 523                               \
 524                                L--M
 525-----------------------------------------------------------------------
 526
 527The `--simplify-by-decoration` option allows you to view only the
 528big picture of the topology of the history, by omitting commits
 529that are not referenced by tags.  Commits are marked as !TREESAME
 530(in other words, kept after history simplification rules described
 531above) if (1) they are referenced by tags, or (2) they change the
 532contents of the paths given on the command line.  All other
 533commits are marked as TREESAME (subject to be simplified away).
 534
 535ifdef::git-rev-list[]
 536Bisection Helpers
 537~~~~~~~~~~~~~~~~~
 538
 539--bisect::
 540        Limit output to the one commit object which is roughly halfway between
 541        included and excluded commits. Note that the bad bisection ref
 542        `refs/bisect/bad` is added to the included commits (if it
 543        exists) and the good bisection refs `refs/bisect/good-*` are
 544        added to the excluded commits (if they exist). Thus, supposing there
 545        are no refs in `refs/bisect/`, if
 546+
 547-----------------------------------------------------------------------
 548        $ git rev-list --bisect foo ^bar ^baz
 549-----------------------------------------------------------------------
 550+
 551outputs 'midpoint', the output of the two commands
 552+
 553-----------------------------------------------------------------------
 554        $ git rev-list foo ^midpoint
 555        $ git rev-list midpoint ^bar ^baz
 556-----------------------------------------------------------------------
 557+
 558would be of roughly the same length.  Finding the change which
 559introduces a regression is thus reduced to a binary search: repeatedly
 560generate and test new 'midpoint's until the commit chain is of length
 561one.
 562
 563--bisect-vars::
 564        This calculates the same as `--bisect`, except that refs in
 565        `refs/bisect/` are not used, and except that this outputs
 566        text ready to be eval'ed by the shell. These lines will assign the
 567        name of the midpoint revision to the variable `bisect_rev`, and the
 568        expected number of commits to be tested after `bisect_rev` is tested
 569        to `bisect_nr`, the expected number of commits to be tested if
 570        `bisect_rev` turns out to be good to `bisect_good`, the expected
 571        number of commits to be tested if `bisect_rev` turns out to be bad to
 572        `bisect_bad`, and the number of commits we are bisecting right now to
 573        `bisect_all`.
 574
 575--bisect-all::
 576        This outputs all the commit objects between the included and excluded
 577        commits, ordered by their distance to the included and excluded
 578        commits. Refs in `refs/bisect/` are not used. The farthest
 579        from them is displayed first. (This is the only one displayed by
 580        `--bisect`.)
 581+
 582This is useful because it makes it easy to choose a good commit to
 583test when you want to avoid to test some of them for some reason (they
 584may not compile for example).
 585+
 586This option can be used along with `--bisect-vars`, in this case,
 587after all the sorted commit objects, there will be the same text as if
 588`--bisect-vars` had been used alone.

 592Commit Ordering
 593~~~~~~~~~~~~~~~
 594
 595By default, the commits are shown in reverse chronological order.
 596
 597--date-order::
 598        Show no parents before all of its children are shown, but
 599        otherwise show commits in the commit timestamp order.
 600
 601--author-date-order::
 602        Show no parents before all of its children are shown, but
 603        otherwise show commits in the author timestamp order.
 604
 605--topo-order::
 606        Show no parents before all of its children are shown, and
 607        avoid showing commits on multiple lines of history
 608        intermixed.
 609+
 610For example, in a commit history like this:
 611+
 612----------------------------------------------------------------
 613
 614    ---1----2----4----7
 615        \              \
 616         3----5----6----8---
 617
 618----------------------------------------------------------------
 619+
 620where the numbers denote the order of commit timestamps, `git
 621rev-list` and friends with `--date-order` show the commits in the
 622timestamp order: 8 7 6 5 4 3 2 1.
 623+
 624With `--topo-order`, they would show 8 6 5 3 7 4 2 1 (or 8 7 4 2 6 5
 6253 1); some older commits are shown before newer ones in order to
 626avoid showing the commits from two parallel development track mixed
 627together.
 628
 629--reverse::
 630        Output the commits in reverse order.
 631        Cannot be combined with `--walk-reflogs`.
 632
 633Object Traversal
 634~~~~~~~~~~~~~~~~
 635
 636These options are mostly targeted for packing of Git repositories.
 637
 638--objects::
 639        Print the object IDs of any object referenced by the listed
 640        commits.  `--objects foo ^bar` thus means ``send me
 641        all object IDs which I need to download if I have the commit
 642        object _bar_ but not _foo_''.
 643
 644--objects-edge::
 645        Similar to `--objects`, but also print the IDs of excluded
 646        commits prefixed with a ``-'' character.  This is used by
 647        linkgit:git-pack-objects[1] to build ``thin'' pack, which records
 648        objects in deltified form based on objects contained in these
 649        excluded commits to reduce network traffic.
 650
 651--unpacked::
 652        Only useful with `--objects`; print the object IDs that are not
 653        in packs.
 654
 655--no-walk[=(sorted|unsorted)]::
 656        Only show the given commits, but do not traverse their ancestors.
 657        This has no effect if a range is specified. If the argument
 658        `unsorted` is given, the commits are shown in the order they were
 659        given on the command line. Otherwise (if `sorted` or no argument
 660        was given), the commits are shown in reverse chronological order
 661        by commit time.
 662
 663--do-walk::
 664        Overrides a previous `--no-walk`.
 665
 666Commit Formatting
 667~~~~~~~~~~~~~~~~~
 668
 669ifdef::git-rev-list[]
 670Using these options, linkgit:git-rev-list[1] will act similar to the
 671more specialized family of commit log tools: linkgit:git-log[1],
 672linkgit:git-show[1], and linkgit:git-whatchanged[1]
 673endif::git-rev-list[]
 674
 675include::pretty-options.txt[]
 676
 677--relative-date::
 678        Synonym for `--date=relative`.
 679
 680--date=(relative|local|default|iso|rfc|short|raw)::
 681        Only takes effect for dates shown in human-readable format, such
 682        as when using `--pretty`. `log.date` config variable sets a default
 683        value for the log command's `--date` option.
 684+
 685`--date=relative` shows dates relative to the current time,
 686e.g. ``2 hours ago''.
 687+
 688`--date=local` shows timestamps in user's local time zone.
 689+
 690`--date=iso` (or `--date=iso8601`) shows timestamps in ISO 8601 format.
 691+
 692`--date=rfc` (or `--date=rfc2822`) shows timestamps in RFC 2822
 693format, often found in email messages.
 694+
 695`--date=short` shows only the date, but not the time, in `YYYY-MM-DD` format.
 696+
 697`--date=raw` shows the date in the internal raw Git format `%s %z` format.
 698+
 699`--date=default` shows timestamps in the original time zone
 700(either committer's or author's).
 701
 702ifdef::git-rev-list[]
 703--header::
 704        Print the contents of the commit in raw-format; each record is
 705        separated with a NUL character.
 706endif::git-rev-list[]
 707
 708--parents::
 709        Print also the parents of the commit (in the form "commit parent...").
 710        Also enables parent rewriting, see 'History Simplification' below.
 711
 712--children::
 713        Print also the children of the commit (in the form "commit child...").
 714        Also enables parent rewriting, see 'History Simplification' below.
 715
 716ifdef::git-rev-list[]
 717--timestamp::
 718        Print the raw commit timestamp.
 719endif::git-rev-list[]
 720
 721--left-right::
 722        Mark which side of a symmetric diff a commit is reachable from.
 723        Commits from the left side are prefixed with `<` and those from
 724        the right with `>`.  If combined with `--boundary`, those
 725        commits are prefixed with `-`.
 726+
 727For example, if you have this topology:
 728+
 729-----------------------------------------------------------------------
 730             y---b---b  branch B
 731            / \ /
 732           /   .
 733          /   / \
 734         o---x---a---a  branch A
 735-----------------------------------------------------------------------
 736+
 737you would get an output like this:
 738+
 739-----------------------------------------------------------------------
 740        $ git rev-list --left-right --boundary --pretty=oneline A...B
 741
 742        >bbbbbbb... 3rd on b
 743        >bbbbbbb... 2nd on b
 744        <aaaaaaa... 3rd on a
 745        <aaaaaaa... 2nd on a
 746        -yyyyyyy... 1st on b
 747        -xxxxxxx... 1st on a
 748-----------------------------------------------------------------------
 749
 750--graph::
 751        Draw a text-based graphical representation of the commit history
 752        on the left hand side of the output.  This may cause extra lines
 753        to be printed in between commits, in order for the graph history
 754        to be drawn properly.
 755+
 756This enables parent rewriting, see 'History Simplification' below.
 757+
 758This implies the `--topo-order` option by default, but the
 759`--date-order` option may also be specified.
 760
 761--show-linear-break[=<barrier>]::
 762        When --graph is not used, all history branches are flattened
 763        which can make it hard to see that the two consecutive commits
 764        do not belong to a linear branch. This option puts a barrier
 765        in between them in that case. If `<barrier>` is specified, it
 766        is the string that will be shown instead of the default one.
 767
 768ifdef::git-rev-list[]
 769--count::
 770        Print a number stating how many commits would have been
 771        listed, and suppress all other output.  When used together
 772        with `--left-right`, instead print the counts for left and
 773        right commits, separated by a tab. When used together with
 774        `--cherry-mark`, omit patch equivalent commits from these
 775        counts and print the count for equivalent commits separated
 776        by a tab.

 780Diff Formatting
 781~~~~~~~~~~~~~~~
 782
 783Listed below are options that control the formatting of diff output.
 784Some of them are specific to linkgit:git-rev-list[1], however other diff
 785options may be given. See linkgit:git-diff-files[1] for more options.
 786
 787-c::
 788        With this option, diff output for a merge commit
 789        shows the differences from each of the parents to the merge result
 790        simultaneously instead of showing pairwise diff between a parent
 791        and the result one at a time. Furthermore, it lists only files
 792        which were modified from all parents.
 793
 794--cc::
 795        This flag implies the `-c` option and further compresses the
 796        patch output by omitting uninteresting hunks whose contents in
 797        the parents have only two variants and the merge result picks
 798        one of them without modification.
 799
 800-m::
 801        This flag makes the merge commits show the full diff like
 802        regular commits; for each merge parent, a separate log entry
 803        and diff is generated. An exception is that only diff against
 804        the first parent is shown when `--first-parent` option is given;
 805        in that case, the output represents the changes the merge
 806        brought _into_ the then-current branch.
 807
 808-r::
 809        Show recursive diffs.
 810
 811-t::
 812        Show the tree objects in the diff output. This implies `-r`.
