   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.

  30--until=<date>::
  31--before=<date>::
  32        Show commits older than a specific date.

  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--ignore-missing::
 157        Upon seeing an invalid object name in the input, pretend as if
 158        the bad input was not given.
 159
 160ifndef::git-rev-list[]
 161--bisect::
 162        Pretend as if the bad bisection ref `refs/bisect/bad`
 163        was listed and as if it was followed by `--not` and the good
 164        bisection refs `refs/bisect/good-*` on the command
 165        line.
 166endif::git-rev-list[]
 167
 168--stdin::
 169        In addition to the '<commit>' listed on the command
 170        line, read them from the standard input. If a '--' separator is
 171        seen, stop reading commits and start reading paths to limit the
 172        result.
 173
 174ifdef::git-rev-list[]
 175--quiet::
 176        Don't print anything to standard output.  This form
 177        is primarily meant to allow the caller to
 178        test the exit status to see if a range of objects is fully
 179        connected (or not).  It is faster than redirecting stdout
 180        to `/dev/null` as the output does not have to be formatted.
 181endif::git-rev-list[]
 182
 183--cherry-mark::
 184        Like `--cherry-pick` (see below) but mark equivalent commits
 185        with `=` rather than omitting them, and inequivalent ones with `+`.
 186
 187--cherry-pick::
 188        Omit any commit that introduces the same change as
 189        another commit on the ``other side'' when the set of
 190        commits are limited with symmetric difference.
 191+
 192For example, if you have two branches, `A` and `B`, a usual way
 193to list all commits on only one side of them is with
 194`--left-right` (see the example below in the description of
 195the `--left-right` option). However, it shows the commits that were
 196cherry-picked from the other branch (for example, ``3rd on b'' may be
 197cherry-picked from branch A). With this option, such pairs of commits are
 198excluded from the output.
 199
 200--left-only::
 201--right-only::
 202        List only commits on the respective side of a symmetric range,
 203        i.e. only those which would be marked `<` resp. `>` by
 204        `--left-right`.
 205+
 206For example, `--cherry-pick --right-only A...B` omits those
 207commits from `B` which are in `A` or are patch-equivalent to a commit in
 208`A`. In other words, this lists the `+` commits from `git cherry A B`.
 209More precisely, `--cherry-pick --right-only --no-merges` gives the exact
 210list.
 211
 212--cherry::
 213        A synonym for `--right-only --cherry-mark --no-merges`; useful to
 214        limit the output to the commits on our side and mark those that
 215        have been applied to the other side of a forked history with
 216        `git log --cherry upstream...mybranch`, similar to
 217        `git cherry upstream mybranch`.
 218
 219-g::
 220--walk-reflogs::
 221        Instead of walking the commit ancestry chain, walk
 222        reflog entries from the most recent one to older ones.
 223        When this option is used you cannot specify commits to
 224        exclude (that is, '{caret}commit', 'commit1..commit2',
 225        nor 'commit1\...commit2' notations cannot be used).
 226+
 227With `--pretty` format other than `oneline` (for obvious reasons),
 228this causes the output to have two extra lines of information
 229taken from the reflog.  By default, 'commit@\{Nth}' notation is
 230used in the output.  When the starting commit is specified as
 231'commit@\{now}', output also uses 'commit@\{timestamp}' notation
 232instead.  Under `--pretty=oneline`, the commit message is
 233prefixed with this information on the same line.
 234This option cannot be combined with `--reverse`.
 235See also linkgit:git-reflog[1].
 236
 237--merge::
 238        After a failed merge, show refs that touch files having a
 239        conflict and don't exist on all heads to merge.
 240
 241--boundary::
 242        Output excluded boundary commits. Boundary commits are
 243        prefixed with `-`.

 247History Simplification
 248~~~~~~~~~~~~~~~~~~~~~~
 249
 250Sometimes you are only interested in parts of the history, for example the
 251commits modifying a particular <path>. But there are two parts of
 252'History Simplification', one part is selecting the commits and the other
 253is how to do it, as there are various strategies to simplify the history.
 254
 255The following options select the commits to be shown:
 256
 257<paths>::
 258        Commits modifying the given <paths> are selected.
 259
 260--simplify-by-decoration::
 261        Commits that are referred by some branch or tag are selected.
 262
 263Note that extra commits can be shown to give a meaningful history.
 264
 265The following options affect the way the simplification is performed:
 266
 267Default mode::
 268        Simplifies the history to the simplest history explaining the
 269        final state of the tree. Simplest because it prunes some side
 270        branches if the end result is the same (i.e. merging branches
 271        with the same content)
 272
 273--full-history::
 274        Same as the default mode, but does not prune some history.
 275
 276--dense::
 277        Only the selected commits are shown, plus some to have a
 278        meaningful history.
 279
 280--sparse::
 281        All commits in the simplified history are shown.
 282
 283--simplify-merges::
 284        Additional option to `--full-history` to remove some needless
 285        merges from the resulting history, as there are no selected
 286        commits contributing to this merge.
 287
 288--ancestry-path::
 289        When given a range of commits to display (e.g. 'commit1..commit2'
 290        or 'commit2 {caret}commit1'), only display commits that exist
 291        directly on the ancestry chain between the 'commit1' and
 292        'commit2', i.e. commits that are both descendants of 'commit1',
 293        and ancestors of 'commit2'.
 294
 295A more detailed explanation follows.
 296
 297Suppose you specified `foo` as the <paths>.  We shall call commits
 298that modify `foo` !TREESAME, and the rest TREESAME.  (In a diff
 299filtered for `foo`, they look different and equal, respectively.)
 300
 301In the following, we will always refer to the same example history to
 302illustrate the differences between simplification settings.  We assume
 303that you are filtering for a file `foo` in this commit graph:
 304-----------------------------------------------------------------------
 305          .-A---M---N---O---P---Q
 306         /     /   /   /   /   /
 307        I     B   C   D   E   Y
 308         \   /   /   /   /   /
 309          `-------------'   X
 310-----------------------------------------------------------------------
 311The horizontal line of history A---Q is taken to be the first parent of
 312each merge.  The commits are:
 313
 314* `I` is the initial commit, in which `foo` exists with contents
 315  ``asdf'', and a file `quux` exists with contents ``quux''. Initial
 316  commits are compared to an empty tree, so `I` is !TREESAME.
 317
 318* In `A`, `foo` contains just ``foo''.
 319
 320* `B` contains the same change as `A`.  Its merge `M` is trivial and
 321  hence TREESAME to all parents.
 322
 323* `C` does not change `foo`, but its merge `N` changes it to ``foobar'',
 324  so it is not TREESAME to any parent.
 325
 326* `D` sets `foo` to ``baz''. Its merge `O` combines the strings from
 327  `N` and `D` to ``foobarbaz''; i.e., it is not TREESAME to any parent.
 328
 329* `E` changes `quux` to ``xyzzy'', and its merge `P` combines the
 330  strings to ``quux xyzzy''. `P` is TREESAME to `O`, but not to `E`.
 331
 332* `X` is an independent root commit that added a new file `side`, and `Y`
 333  modified it. `Y` is TREESAME to `X`. Its merge `Q` added `side` to `P`, and
 334  `Q` is TREESAME to `P`, but not to `Y`.
 335
 336`rev-list` walks backwards through history, including or excluding
 337commits based on whether `--full-history` and/or parent rewriting
 338(via `--parents` or `--children`) are used. The following settings
 339are available.
 340
 341Default mode::
 342        Commits are included if they are not TREESAME to any parent
 343        (though this can be changed, see `--sparse` below).  If the
 344        commit was a merge, and it was TREESAME to one parent, follow
 345        only that parent.  (Even if there are several TREESAME
 346        parents, follow only one of them.)  Otherwise, follow all
 347        parents.
 348+
 349This results in:
 350+
 351-----------------------------------------------------------------------
 352          .-A---N---O
 353         /     /   /
 354        I---------D
 355-----------------------------------------------------------------------
 356+
 357Note how the rule to only follow the TREESAME parent, if one is
 358available, removed `B` from consideration entirely.  `C` was
 359considered via `N`, but is TREESAME.  Root commits are compared to an
 360empty tree, so `I` is !TREESAME.
 361+
 362Parent/child relations are only visible with `--parents`, but that does
 363not affect the commits selected in default mode, so we have shown the
 364parent lines.
 365
 366--full-history without parent rewriting::
 367        This mode differs from the default in one point: always follow
 368        all parents of a merge, even if it is TREESAME to one of them.
 369        Even if more than one side of the merge has commits that are
 370        included, this does not imply that the merge itself is!  In
 371        the example, we get
 372+
 373-----------------------------------------------------------------------
 374        I  A  B  N  D  O  P  Q
 375-----------------------------------------------------------------------
 376+
 377`M` was excluded because it is TREESAME to both parents.  `E`,
 378`C` and `B` were all walked, but only `B` was !TREESAME, so the others
 379do not appear.
 380+
 381Note that without parent rewriting, it is not really possible to talk
 382about the parent/child relationships between the commits, so we show
 383them disconnected.
 384
 385--full-history with parent rewriting::
 386        Ordinary commits are only included if they are !TREESAME
 387        (though this can be changed, see `--sparse` below).
 388+
 389Merges are always included.  However, their parent list is rewritten:
 390Along each parent, prune away commits that are not included
 391themselves.  This results in
 392+
 393-----------------------------------------------------------------------
 394          .-A---M---N---O---P---Q
 395         /     /   /   /   /
 396        I     B   /   D   /
 397         \   /   /   /   /
 398          `-------------'
 399-----------------------------------------------------------------------
 400+
 401Compare to `--full-history` without rewriting above.  Note that `E`
 402was pruned away because it is TREESAME, but the parent list of P was
 403rewritten to contain `E`'s parent `I`.  The same happened for `C` and
 404`N`, and `X`, `Y` and `Q`.
 405
 406In addition to the above settings, you can change whether TREESAME
 407affects inclusion:
 408
 409--dense::
 410        Commits that are walked are included if they are not TREESAME
 411        to any parent.
 412
 413--sparse::
 414        All commits that are walked are included.
 415+
 416Note that without `--full-history`, this still simplifies merges: if
 417one of the parents is TREESAME, we follow only that one, so the other
 418sides of the merge are never walked.
 419
 420--simplify-merges::
 421        First, build a history graph in the same way that
 422        `--full-history` with parent rewriting does (see above).
 423+
 424Then simplify each commit `C` to its replacement `C'` in the final
 425history according to the following rules:
 426+
 427--
 428* Set `C'` to `C`.
 429+
 430* Replace each parent `P` of `C'` with its simplification `P'`.  In
 431  the process, drop parents that are ancestors of other parents or that are
 432  root commits TREESAME to an empty tree, and remove duplicates, but take care
 433  to never drop all parents that we are TREESAME to.
 434+
 435* If after this parent rewriting, `C'` is a root or merge commit (has
 436  zero or >1 parents), a boundary commit, or !TREESAME, it remains.
 437  Otherwise, it is replaced with its only parent.
 438--
 439+
 440The effect of this is best shown by way of comparing to
 441`--full-history` with parent rewriting.  The example turns into:
 442+
 443-----------------------------------------------------------------------
 444          .-A---M---N---O
 445         /     /       /
 446        I     B       D
 447         \   /       /
 448          `---------'
 449-----------------------------------------------------------------------
 450+
 451Note the major differences in `N`, `P`, and `Q` over `--full-history`:
 452+
 453--
 454* `N`'s parent list had `I` removed, because it is an ancestor of the
 455  other parent `M`.  Still, `N` remained because it is !TREESAME.
 456+
 457* `P`'s parent list similarly had `I` removed.  `P` was then
 458  removed completely, because it had one parent and is TREESAME.
 459+
 460* `Q`'s parent list had `Y` simplified to `X`. `X` was then removed, because it
 461  was a TREESAME root. `Q` was then removed completely, because it had one
 462  parent and is TREESAME.
 463--
 464
 465Finally, there is a fifth simplification mode available:
 466
 467--ancestry-path::
 468        Limit the displayed commits to those directly on the ancestry
 469        chain between the ``from'' and ``to'' commits in the given commit
 470        range. I.e. only display commits that are ancestor of the ``to''
 471        commit and descendants of the ``from'' commit.
 472+
 473As an example use case, consider the following commit history:
 474+
 475-----------------------------------------------------------------------
 476            D---E-------F
 477           /     \       \
 478          B---C---G---H---I---J
 479         /                     \
 480        A-------K---------------L--M
 481-----------------------------------------------------------------------
 482+
 483A regular 'D..M' computes the set of commits that are ancestors of `M`,
 484but excludes the ones that are ancestors of `D`. This is useful to see
 485what happened to the history leading to `M` since `D`, in the sense
 486that ``what does `M` have that did not exist in `D`''. The result in this
 487example would be all the commits, except `A` and `B` (and `D` itself,
 488of course).
 489+
 490When we want to find out what commits in `M` are contaminated with the
 491bug introduced by `D` and need fixing, however, we might want to view
 492only the subset of 'D..M' that are actually descendants of `D`, i.e.
 493excluding `C` and `K`. This is exactly what the `--ancestry-path`
 494option does. Applied to the 'D..M' range, it results in:
 495+
 496-----------------------------------------------------------------------
 497                E-------F
 498                 \       \
 499                  G---H---I---J
 500                               \
 501                                L--M
 502-----------------------------------------------------------------------
 503
 504The `--simplify-by-decoration` option allows you to view only the
 505big picture of the topology of the history, by omitting commits
 506that are not referenced by tags.  Commits are marked as !TREESAME
 507(in other words, kept after history simplification rules described
 508above) if (1) they are referenced by tags, or (2) they change the
 509contents of the paths given on the command line.  All other
 510commits are marked as TREESAME (subject to be simplified away).

 513Bisection Helpers
 514~~~~~~~~~~~~~~~~~
 515
 516--bisect::
 517        Limit output to the one commit object which is roughly halfway between
 518        included and excluded commits. Note that the bad bisection ref
 519        `refs/bisect/bad` is added to the included commits (if it
 520        exists) and the good bisection refs `refs/bisect/good-*` are
 521        added to the excluded commits (if they exist). Thus, supposing there
 522        are no refs in `refs/bisect/`, if
 523+
 524-----------------------------------------------------------------------
 525        $ git rev-list --bisect foo ^bar ^baz
 526-----------------------------------------------------------------------
 527+
 528outputs 'midpoint', the output of the two commands
 529+
 530-----------------------------------------------------------------------
 531        $ git rev-list foo ^midpoint
 532        $ git rev-list midpoint ^bar ^baz
 533-----------------------------------------------------------------------
 534+
 535would be of roughly the same length.  Finding the change which
 536introduces a regression is thus reduced to a binary search: repeatedly
 537generate and test new 'midpoint's until the commit chain is of length
 538one.
 539
 540--bisect-vars::
 541        This calculates the same as `--bisect`, except that refs in
 542        `refs/bisect/` are not used, and except that this outputs
 543        text ready to be eval'ed by the shell. These lines will assign the
 544        name of the midpoint revision to the variable `bisect_rev`, and the
 545        expected number of commits to be tested after `bisect_rev` is tested
 546        to `bisect_nr`, the expected number of commits to be tested if
 547        `bisect_rev` turns out to be good to `bisect_good`, the expected
 548        number of commits to be tested if `bisect_rev` turns out to be bad to
 549        `bisect_bad`, and the number of commits we are bisecting right now to
 550        `bisect_all`.
 551
 552--bisect-all::
 553        This outputs all the commit objects between the included and excluded
 554        commits, ordered by their distance to the included and excluded
 555        commits. Refs in `refs/bisect/` are not used. The farthest
 556        from them is displayed first. (This is the only one displayed by
 557        `--bisect`.)
 558+
 559This is useful because it makes it easy to choose a good commit to
 560test when you want to avoid to test some of them for some reason (they
 561may not compile for example).
 562+
 563This option can be used along with `--bisect-vars`, in this case,
 564after all the sorted commit objects, there will be the same text as if
 565`--bisect-vars` had been used alone.

 568
 569Commit Ordering
 570~~~~~~~~~~~~~~~
 571
 572By default, the commits are shown in reverse chronological order.
 573
 574--date-order::
 575        Show no parents before all of its children are shown, but
 576        otherwise show commits in the commit timestamp order.
 577
 578--author-date-order::
 579        Show no parents before all of its children are shown, but
 580        otherwise show commits in the author timestamp order.
 581
 582--topo-order::
 583        Show no parents before all of its children are shown, and
 584        avoid showing commits on multiple lines of history
 585        intermixed.
 586+
 587For example, in a commit history like this:
 588+
 589----------------------------------------------------------------
 590
 591    ---1----2----4----7
 592        \              \
 593         3----5----6----8---
 594
 595----------------------------------------------------------------
 596+
 597where the numbers denote the order of commit timestamps, `git
 598rev-list` and friends with `--date-order` show the commits in the
 599timestamp order: 8 7 6 5 4 3 2 1.
 600+
 601With `--topo-order`, they would show 8 6 5 3 7 4 2 1 (or 8 7 4 2 6 5
 6023 1); some older commits are shown before newer ones in order to
 603avoid showing the commits from two parallel development track mixed
 604together.
 605
 606--reverse::
 607        Output the commits in reverse order.
 608        Cannot be combined with `--walk-reflogs`.
 609
 610Object Traversal
 611~~~~~~~~~~~~~~~~
 612
 613These options are mostly targeted for packing of Git repositories.
 614
 615--objects::
 616        Print the object IDs of any object referenced by the listed
 617        commits.  `--objects foo ^bar` thus means ``send me
 618        all object IDs which I need to download if I have the commit
 619        object _bar_ but not _foo_''.
 620
 621--objects-edge::
 622        Similar to `--objects`, but also print the IDs of excluded
 623        commits prefixed with a ``-'' character.  This is used by
 624        linkgit:git-pack-objects[1] to build ``thin'' pack, which records
 625        objects in deltified form based on objects contained in these
 626        excluded commits to reduce network traffic.
 627
 628--unpacked::
 629        Only useful with `--objects`; print the object IDs that are not
 630        in packs.
 631
 632--no-walk[=(sorted|unsorted)]::
 633        Only show the given commits, but do not traverse their ancestors.
 634        This has no effect if a range is specified. If the argument
 635        `unsorted` is given, the commits are shown in the order they were
 636        given on the command line. Otherwise (if `sorted` or no argument
 637        was given), the commits are shown in reverse chronological order
 638        by commit time.
 639
 640--do-walk::
 641        Overrides a previous `--no-walk`.
 642
 643Commit Formatting
 644~~~~~~~~~~~~~~~~~
 645
 646ifdef::git-rev-list[]
 647Using these options, linkgit:git-rev-list[1] will act similar to the
 648more specialized family of commit log tools: linkgit:git-log[1],
 649linkgit:git-show[1], and linkgit:git-whatchanged[1]
 650endif::git-rev-list[]
 651
 652include::pretty-options.txt[]
 653
 654--relative-date::
 655        Synonym for `--date=relative`.
 656
 657--date=(relative|local|default|iso|rfc|short|raw)::
 658        Only takes effect for dates shown in human-readable format, such
 659        as when using `--pretty`. `log.date` config variable sets a default
 660        value for the log command's `--date` option.
 661+
 662`--date=relative` shows dates relative to the current time,
 663e.g. ``2 hours ago''.
 664+
 665`--date=local` shows timestamps in user's local time zone.
 666+
 667`--date=iso` (or `--date=iso8601`) shows timestamps in ISO 8601 format.
 668+
 669`--date=rfc` (or `--date=rfc2822`) shows timestamps in RFC 2822
 670format, often found in email messages.
 671+
 672`--date=short` shows only the date, but not the time, in `YYYY-MM-DD` format.
 673+
 674`--date=raw` shows the date in the internal raw Git format `%s %z` format.
 675+
 676`--date=default` shows timestamps in the original time zone
 677(either committer's or author's).
 678
 679ifdef::git-rev-list[]
 680--header::
 681        Print the contents of the commit in raw-format; each record is
 682        separated with a NUL character.
 683endif::git-rev-list[]
 684
 685--parents::
 686        Print also the parents of the commit (in the form "commit parent...").
 687        Also enables parent rewriting, see 'History Simplification' below.
 688
 689--children::
 690        Print also the children of the commit (in the form "commit child...").
 691        Also enables parent rewriting, see 'History Simplification' below.
 692
 693ifdef::git-rev-list[]
 694--timestamp::
 695        Print the raw commit timestamp.
 696endif::git-rev-list[]
 697
 698--left-right::
 699        Mark which side of a symmetric diff a commit is reachable from.
 700        Commits from the left side are prefixed with `<` and those from
 701        the right with `>`.  If combined with `--boundary`, those
 702        commits are prefixed with `-`.
 703+
 704For example, if you have this topology:
 705+
 706-----------------------------------------------------------------------
 707             y---b---b  branch B
 708            / \ /
 709           /   .
 710          /   / \
 711         o---x---a---a  branch A
 712-----------------------------------------------------------------------
 713+
 714you would get an output like this:
 715+
 716-----------------------------------------------------------------------
 717        $ git rev-list --left-right --boundary --pretty=oneline A...B
 718
 719        >bbbbbbb... 3rd on b
 720        >bbbbbbb... 2nd on b
 721        <aaaaaaa... 3rd on a
 722        <aaaaaaa... 2nd on a
 723        -yyyyyyy... 1st on b
 724        -xxxxxxx... 1st on a
 725-----------------------------------------------------------------------
 726
 727--graph::
 728        Draw a text-based graphical representation of the commit history
 729        on the left hand side of the output.  This may cause extra lines
 730        to be printed in between commits, in order for the graph history
 731        to be drawn properly.
 732+
 733This enables parent rewriting, see 'History Simplification' below.
 734+
 735This implies the `--topo-order` option by default, but the
 736`--date-order` option may also be specified.
 737
 738ifdef::git-rev-list[]
 739--count::
 740        Print a number stating how many commits would have been
 741        listed, and suppress all other output.  When used together
 742        with `--left-right`, instead print the counts for left and
 743        right commits, separated by a tab. When used together with
 744        `--cherry-mark`, omit patch equivalent commits from these
 745        counts and print the count for equivalent commits separated
 746        by a tab.

 750Diff Formatting
 751~~~~~~~~~~~~~~~
 752
 753Listed below are options that control the formatting of diff output.
 754Some of them are specific to linkgit:git-rev-list[1], however other diff
 755options may be given. See linkgit:git-diff-files[1] for more options.
 756
 757-c::
 758        With this option, diff output for a merge commit
 759        shows the differences from each of the parents to the merge result
 760        simultaneously instead of showing pairwise diff between a parent
 761        and the result one at a time. Furthermore, it lists only files
 762        which were modified from all parents.
 763
 764--cc::
 765        This flag implies the `-c` option and further compresses the
 766        patch output by omitting uninteresting hunks whose contents in
 767        the parents have only two variants and the merge result picks
 768        one of them without modification.
 769
 770-m::
 771        This flag makes the merge commits show the full diff like
 772        regular commits; for each merge parent, a separate log entry
 773        and diff is generated. An exception is that only diff against
 774        the first parent is shown when `--first-parent` option is given;
 775        in that case, the output represents the changes the merge
 776        brought _into_ the then-current branch.
 777
 778-r::
 779        Show recursive diffs.
 780
 781-t::
 782        Show the tree objects in the diff output. This implies `-r`.
