   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        accumulated 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--reflog::
 172        Pretend as if all objects mentioned by reflogs are listed on the
 173        command line as `<commit>`.
 174
 175--ignore-missing::
 176        Upon seeing an invalid object name in the input, pretend as if
 177        the bad input was not given.
 178
 179ifndef::git-rev-list[]
 180--bisect::
 181        Pretend as if the bad bisection ref `refs/bisect/bad`
 182        was listed and as if it was followed by `--not` and the good
 183        bisection refs `refs/bisect/good-*` on the command
 184        line.
 185endif::git-rev-list[]
 186
 187--stdin::
 188        In addition to the '<commit>' listed on the command
 189        line, read them from the standard input. If a '--' separator is
 190        seen, stop reading commits and start reading paths to limit the
 191        result.
 192
 193ifdef::git-rev-list[]
 194--quiet::
 195        Don't print anything to standard output.  This form
 196        is primarily meant to allow the caller to
 197        test the exit status to see if a range of objects is fully
 198        connected (or not).  It is faster than redirecting stdout
 199        to `/dev/null` as the output does not have to be formatted.
 200endif::git-rev-list[]
 201
 202--cherry-mark::
 203        Like `--cherry-pick` (see below) but mark equivalent commits
 204        with `=` rather than omitting them, and inequivalent ones with `+`.
 205
 206--cherry-pick::
 207        Omit any commit that introduces the same change as
 208        another commit on the ``other side'' when the set of
 209        commits are limited with symmetric difference.
 210+
 211For example, if you have two branches, `A` and `B`, a usual way
 212to list all commits on only one side of them is with
 213`--left-right` (see the example below in the description of
 214the `--left-right` option). However, it shows the commits that were
 215cherry-picked from the other branch (for example, ``3rd on b'' may be
 216cherry-picked from branch A). With this option, such pairs of commits are
 217excluded from the output.
 218
 219--left-only::
 220--right-only::
 221        List only commits on the respective side of a symmetric range,
 222        i.e. only those which would be marked `<` resp. `>` by
 223        `--left-right`.
 224+
 225For example, `--cherry-pick --right-only A...B` omits those
 226commits from `B` which are in `A` or are patch-equivalent to a commit in
 227`A`. In other words, this lists the `+` commits from `git cherry A B`.
 228More precisely, `--cherry-pick --right-only --no-merges` gives the exact
 229list.
 230
 231--cherry::
 232        A synonym for `--right-only --cherry-mark --no-merges`; useful to
 233        limit the output to the commits on our side and mark those that
 234        have been applied to the other side of a forked history with
 235        `git log --cherry upstream...mybranch`, similar to
 236        `git cherry upstream mybranch`.
 237
 238-g::
 239--walk-reflogs::
 240        Instead of walking the commit ancestry chain, walk
 241        reflog entries from the most recent one to older ones.
 242        When this option is used you cannot specify commits to
 243        exclude (that is, '{caret}commit', 'commit1..commit2',
 244        and 'commit1\...commit2' notations cannot be used).
 245+
 246With `--pretty` format other than `oneline` (for obvious reasons),
 247this causes the output to have two extra lines of information
 248taken from the reflog.  By default, 'commit@\{Nth}' notation is
 249used in the output.  When the starting commit is specified as
 250'commit@\{now}', output also uses 'commit@\{timestamp}' notation
 251instead.  Under `--pretty=oneline`, the commit message is
 252prefixed with this information on the same line.
 253This option cannot be combined with `--reverse`.
 254See also linkgit:git-reflog[1].
 255
 256--merge::
 257        After a failed merge, show refs that touch files having a
 258        conflict and don't exist on all heads to merge.
 259
 260--boundary::
 261        Output excluded boundary commits. Boundary commits are
 262        prefixed with `-`.
 263
 264ifdef::git-rev-list[]
 265--use-bitmap-index::
 266
 267        Try to speed up the traversal using the pack bitmap index (if
 268        one is available). Note that when traversing with `--objects`,
 269        trees and blobs will not have their associated path printed.

 274History Simplification
 275~~~~~~~~~~~~~~~~~~~~~~
 276
 277Sometimes you are only interested in parts of the history, for example the
 278commits modifying a particular <path>. But there are two parts of
 279'History Simplification', one part is selecting the commits and the other
 280is how to do it, as there are various strategies to simplify the history.
 281
 282The following options select the commits to be shown:
 283
 284<paths>::
 285        Commits modifying the given <paths> are selected.
 286
 287--simplify-by-decoration::
 288        Commits that are referred by some branch or tag are selected.
 289
 290Note that extra commits can be shown to give a meaningful history.
 291
 292The following options affect the way the simplification is performed:
 293
 294Default mode::
 295        Simplifies the history to the simplest history explaining the
 296        final state of the tree. Simplest because it prunes some side
 297        branches if the end result is the same (i.e. merging branches
 298        with the same content)
 299
 300--full-history::
 301        Same as the default mode, but does not prune some history.
 302
 303--dense::
 304        Only the selected commits are shown, plus some to have a
 305        meaningful history.
 306
 307--sparse::
 308        All commits in the simplified history are shown.
 309
 310--simplify-merges::
 311        Additional option to `--full-history` to remove some needless
 312        merges from the resulting history, as there are no selected
 313        commits contributing to this merge.
 314
 315--ancestry-path::
 316        When given a range of commits to display (e.g. 'commit1..commit2'
 317        or 'commit2 {caret}commit1'), only display commits that exist
 318        directly on the ancestry chain between the 'commit1' and
 319        'commit2', i.e. commits that are both descendants of 'commit1',
 320        and ancestors of 'commit2'.
 321
 322A more detailed explanation follows.
 323
 324Suppose you specified `foo` as the <paths>.  We shall call commits
 325that modify `foo` !TREESAME, and the rest TREESAME.  (In a diff
 326filtered for `foo`, they look different and equal, respectively.)
 327
 328In the following, we will always refer to the same example history to
 329illustrate the differences between simplification settings.  We assume
 330that you are filtering for a file `foo` in this commit graph:
 331-----------------------------------------------------------------------
 332          .-A---M---N---O---P---Q
 333         /     /   /   /   /   /
 334        I     B   C   D   E   Y
 335         \   /   /   /   /   /
 336          `-------------'   X
 337-----------------------------------------------------------------------
 338The horizontal line of history A---Q is taken to be the first parent of
 339each merge.  The commits are:
 340
 341* `I` is the initial commit, in which `foo` exists with contents
 342  ``asdf'', and a file `quux` exists with contents ``quux''. Initial
 343  commits are compared to an empty tree, so `I` is !TREESAME.
 344
 345* In `A`, `foo` contains just ``foo''.
 346
 347* `B` contains the same change as `A`.  Its merge `M` is trivial and
 348  hence TREESAME to all parents.
 349
 350* `C` does not change `foo`, but its merge `N` changes it to ``foobar'',
 351  so it is not TREESAME to any parent.
 352
 353* `D` sets `foo` to ``baz''. Its merge `O` combines the strings from
 354  `N` and `D` to ``foobarbaz''; i.e., it is not TREESAME to any parent.
 355
 356* `E` changes `quux` to ``xyzzy'', and its merge `P` combines the
 357  strings to ``quux xyzzy''. `P` is TREESAME to `O`, but not to `E`.
 358
 359* `X` is an independent root commit that added a new file `side`, and `Y`
 360  modified it. `Y` is TREESAME to `X`. Its merge `Q` added `side` to `P`, and
 361  `Q` is TREESAME to `P`, but not to `Y`.
 362
 363`rev-list` walks backwards through history, including or excluding
 364commits based on whether `--full-history` and/or parent rewriting
 365(via `--parents` or `--children`) are used. The following settings
 366are available.
 367
 368Default mode::
 369        Commits are included if they are not TREESAME to any parent
 370        (though this can be changed, see `--sparse` below).  If the
 371        commit was a merge, and it was TREESAME to one parent, follow
 372        only that parent.  (Even if there are several TREESAME
 373        parents, follow only one of them.)  Otherwise, follow all
 374        parents.
 375+
 376This results in:
 377+
 378-----------------------------------------------------------------------
 379          .-A---N---O
 380         /     /   /
 381        I---------D
 382-----------------------------------------------------------------------
 383+
 384Note how the rule to only follow the TREESAME parent, if one is
 385available, removed `B` from consideration entirely.  `C` was
 386considered via `N`, but is TREESAME.  Root commits are compared to an
 387empty tree, so `I` is !TREESAME.
 388+
 389Parent/child relations are only visible with `--parents`, but that does
 390not affect the commits selected in default mode, so we have shown the
 391parent lines.
 392
 393--full-history without parent rewriting::
 394        This mode differs from the default in one point: always follow
 395        all parents of a merge, even if it is TREESAME to one of them.
 396        Even if more than one side of the merge has commits that are
 397        included, this does not imply that the merge itself is!  In
 398        the example, we get
 399+
 400-----------------------------------------------------------------------
 401        I  A  B  N  D  O  P  Q
 402-----------------------------------------------------------------------
 403+
 404`M` was excluded because it is TREESAME to both parents.  `E`,
 405`C` and `B` were all walked, but only `B` was !TREESAME, so the others
 406do not appear.
 407+
 408Note that without parent rewriting, it is not really possible to talk
 409about the parent/child relationships between the commits, so we show
 410them disconnected.
 411
 412--full-history with parent rewriting::
 413        Ordinary commits are only included if they are !TREESAME
 414        (though this can be changed, see `--sparse` below).
 415+
 416Merges are always included.  However, their parent list is rewritten:
 417Along each parent, prune away commits that are not included
 418themselves.  This results in
 419+
 420-----------------------------------------------------------------------
 421          .-A---M---N---O---P---Q
 422         /     /   /   /   /
 423        I     B   /   D   /
 424         \   /   /   /   /
 425          `-------------'
 426-----------------------------------------------------------------------
 427+
 428Compare to `--full-history` without rewriting above.  Note that `E`
 429was pruned away because it is TREESAME, but the parent list of P was
 430rewritten to contain `E`'s parent `I`.  The same happened for `C` and
 431`N`, and `X`, `Y` and `Q`.
 432
 433In addition to the above settings, you can change whether TREESAME
 434affects inclusion:
 435
 436--dense::
 437        Commits that are walked are included if they are not TREESAME
 438        to any parent.
 439
 440--sparse::
 441        All commits that are walked are included.
 442+
 443Note that without `--full-history`, this still simplifies merges: if
 444one of the parents is TREESAME, we follow only that one, so the other
 445sides of the merge are never walked.
 446
 447--simplify-merges::
 448        First, build a history graph in the same way that
 449        `--full-history` with parent rewriting does (see above).
 450+
 451Then simplify each commit `C` to its replacement `C'` in the final
 452history according to the following rules:
 453+
 454--
 455* Set `C'` to `C`.
 456+
 457* Replace each parent `P` of `C'` with its simplification `P'`.  In
 458  the process, drop parents that are ancestors of other parents or that are
 459  root commits TREESAME to an empty tree, and remove duplicates, but take care
 460  to never drop all parents that we are TREESAME to.
 461+
 462* If after this parent rewriting, `C'` is a root or merge commit (has
 463  zero or >1 parents), a boundary commit, or !TREESAME, it remains.
 464  Otherwise, it is replaced with its only parent.
 465--
 466+
 467The effect of this is best shown by way of comparing to
 468`--full-history` with parent rewriting.  The example turns into:
 469+

 477+
 478Note the major differences in `N`, `P`, and `Q` over `--full-history`:
 479+
 480--
 481* `N`'s parent list had `I` removed, because it is an ancestor of the
 482  other parent `M`.  Still, `N` remained because it is !TREESAME.
 483+
 484* `P`'s parent list similarly had `I` removed.  `P` was then
 485  removed completely, because it had one parent and is TREESAME.
 486+
 487* `Q`'s parent list had `Y` simplified to `X`. `X` was then removed, because it
 488  was a TREESAME root. `Q` was then removed completely, because it had one
 489  parent and is TREESAME.
 490--
 491
 492Finally, there is a fifth simplification mode available:
 493
 494--ancestry-path::
 495        Limit the displayed commits to those directly on the ancestry
 496        chain between the ``from'' and ``to'' commits in the given commit
 497        range. I.e. only display commits that are ancestor of the ``to''
 498        commit and descendants of the ``from'' commit.
 499+
 500As an example use case, consider the following commit history:
 501+
 502-----------------------------------------------------------------------
 503            D---E-------F
 504           /     \       \
 505          B---C---G---H---I---J
 506         /                     \
 507        A-------K---------------L--M
 508-----------------------------------------------------------------------
 509+
 510A regular 'D..M' computes the set of commits that are ancestors of `M`,
 511but excludes the ones that are ancestors of `D`. This is useful to see
 512what happened to the history leading to `M` since `D`, in the sense
 513that ``what does `M` have that did not exist in `D`''. The result in this
 514example would be all the commits, except `A` and `B` (and `D` itself,
 515of course).
 516+
 517When we want to find out what commits in `M` are contaminated with the
 518bug introduced by `D` and need fixing, however, we might want to view
 519only the subset of 'D..M' that are actually descendants of `D`, i.e.
 520excluding `C` and `K`. This is exactly what the `--ancestry-path`
 521option does. Applied to the 'D..M' range, it results in:
 522+
 523-----------------------------------------------------------------------
 524                E-------F
 525                 \       \
 526                  G---H---I---J
 527                               \
 528                                L--M
 529-----------------------------------------------------------------------
 530
 531The `--simplify-by-decoration` option allows you to view only the
 532big picture of the topology of the history, by omitting commits
 533that are not referenced by tags.  Commits are marked as !TREESAME
 534(in other words, kept after history simplification rules described
 535above) if (1) they are referenced by tags, or (2) they change the
 536contents of the paths given on the command line.  All other
 537commits are marked as TREESAME (subject to be simplified away).

 540Bisection Helpers
 541~~~~~~~~~~~~~~~~~
 542
 543--bisect::
 544        Limit output to the one commit object which is roughly halfway between
 545        included and excluded commits. Note that the bad bisection ref
 546        `refs/bisect/bad` is added to the included commits (if it
 547        exists) and the good bisection refs `refs/bisect/good-*` are
 548        added to the excluded commits (if they exist). Thus, supposing there
 549        are no refs in `refs/bisect/`, if
 550+
 551-----------------------------------------------------------------------
 552        $ git rev-list --bisect foo ^bar ^baz
 553-----------------------------------------------------------------------
 554+
 555outputs 'midpoint', the output of the two commands
 556+
 557-----------------------------------------------------------------------
 558        $ git rev-list foo ^midpoint
 559        $ git rev-list midpoint ^bar ^baz
 560-----------------------------------------------------------------------
 561+
 562would be of roughly the same length.  Finding the change which
 563introduces a regression is thus reduced to a binary search: repeatedly
 564generate and test new 'midpoint's until the commit chain is of length
 565one.
 566
 567--bisect-vars::
 568        This calculates the same as `--bisect`, except that refs in
 569        `refs/bisect/` are not used, and except that this outputs
 570        text ready to be eval'ed by the shell. These lines will assign the
 571        name of the midpoint revision to the variable `bisect_rev`, and the
 572        expected number of commits to be tested after `bisect_rev` is tested
 573        to `bisect_nr`, the expected number of commits to be tested if
 574        `bisect_rev` turns out to be good to `bisect_good`, the expected
 575        number of commits to be tested if `bisect_rev` turns out to be bad to
 576        `bisect_bad`, and the number of commits we are bisecting right now to
 577        `bisect_all`.
 578
 579--bisect-all::
 580        This outputs all the commit objects between the included and excluded
 581        commits, ordered by their distance to the included and excluded
 582        commits. Refs in `refs/bisect/` are not used. The farthest
 583        from them is displayed first. (This is the only one displayed by
 584        `--bisect`.)
 585+
 586This is useful because it makes it easy to choose a good commit to
 587test when you want to avoid to test some of them for some reason (they
 588may not compile for example).
 589+
 590This option can be used along with `--bisect-vars`, in this case,
 591after all the sorted commit objects, there will be the same text as if
 592`--bisect-vars` had been used alone.

 595
 596Commit Ordering
 597~~~~~~~~~~~~~~~
 598
 599By default, the commits are shown in reverse chronological order.
 600
 601--date-order::
 602        Show no parents before all of its children are shown, but
 603        otherwise show commits in the commit timestamp order.
 604
 605--author-date-order::
 606        Show no parents before all of its children are shown, but
 607        otherwise show commits in the author timestamp order.
 608
 609--topo-order::
 610        Show no parents before all of its children are shown, and
 611        avoid showing commits on multiple lines of history
 612        intermixed.
 613+
 614For example, in a commit history like this:
 615+
 616----------------------------------------------------------------
 617
 618    ---1----2----4----7
 619        \              \
 620         3----5----6----8---
 621
 622----------------------------------------------------------------
 623+
 624where the numbers denote the order of commit timestamps, `git
 625rev-list` and friends with `--date-order` show the commits in the
 626timestamp order: 8 7 6 5 4 3 2 1.
 627+
 628With `--topo-order`, they would show 8 6 5 3 7 4 2 1 (or 8 7 4 2 6 5
 6293 1); some older commits are shown before newer ones in order to
 630avoid showing the commits from two parallel development track mixed
 631together.
 632
 633--reverse::
 634        Output the commits in reverse order.
 635        Cannot be combined with `--walk-reflogs`.
 636
 637Object Traversal
 638~~~~~~~~~~~~~~~~
 639
 640These options are mostly targeted for packing of Git repositories.
 641
 642ifdef::git-rev-list[]
 643--objects::
 644        Print the object IDs of any object referenced by the listed
 645        commits.  `--objects foo ^bar` thus means ``send me
 646        all object IDs which I need to download if I have the commit
 647        object _bar_ but not _foo_''.
 648
 649--objects-edge::
 650        Similar to `--objects`, but also print the IDs of excluded
 651        commits prefixed with a ``-'' character.  This is used by
 652        linkgit:git-pack-objects[1] to build a ``thin'' pack, which records
 653        objects in deltified form based on objects contained in these
 654        excluded commits to reduce network traffic.
 655
 656--objects-edge-aggressive::
 657        Similar to `--objects-edge`, but it tries harder to find excluded
 658        commits at the cost of increased time.  This is used instead of
 659        `--objects-edge` to build ``thin'' packs for shallow repositories.
 660
 661--indexed-objects::
 662        Pretend as if all trees and blobs used by the index are listed
 663        on the command line.  Note that you probably want to use
 664        `--objects`, too.
 665
 666--unpacked::
 667        Only useful with `--objects`; print the object IDs that are not
 668        in packs.
 669endif::git-rev-list[]
 670
 671--no-walk[=(sorted|unsorted)]::
 672        Only show the given commits, but do not traverse their ancestors.
 673        This has no effect if a range is specified. If the argument
 674        `unsorted` is given, the commits are shown in the order they were
 675        given on the command line. Otherwise (if `sorted` or no argument
 676        was given), the commits are shown in reverse chronological order
 677        by commit time.
 678
 679--do-walk::
 680        Overrides a previous `--no-walk`.
 681
 682Commit Formatting
 683~~~~~~~~~~~~~~~~~
 684
 685ifdef::git-rev-list[]
 686Using these options, linkgit:git-rev-list[1] will act similar to the
 687more specialized family of commit log tools: linkgit:git-log[1],
 688linkgit:git-show[1], and linkgit:git-whatchanged[1]
 689endif::git-rev-list[]
 690
 691include::pretty-options.txt[]
 692
 693--relative-date::
 694        Synonym for `--date=relative`.
 695
 696--date=(relative|local|default|iso|iso-strict|rfc|short|raw)::
 697        Only takes effect for dates shown in human-readable format, such
 698        as when using `--pretty`. `log.date` config variable sets a default
 699        value for the log command's `--date` option.
 700+
 701`--date=relative` shows dates relative to the current time,
 702e.g. ``2 hours ago''.
 703+
 704`--date=local` shows timestamps in user's local time zone.
 705+
 706`--date=iso` (or `--date=iso8601`) shows timestamps in a ISO 8601-like format.
 707The differences to the strict ISO 8601 format are:
 708
 709        - a space instead of the `T` date/time delimiter
 710        - a space between time and time zone
 711        - no colon between hours and minutes of the time zone
 712
 713+
 714`--date=iso-strict` (or `--date=iso8601-strict`) shows timestamps in strict
 715ISO 8601 format.
 716+
 717`--date=rfc` (or `--date=rfc2822`) shows timestamps in RFC 2822
 718format, often found in email messages.
 719+
 720`--date=short` shows only the date, but not the time, in `YYYY-MM-DD` format.
 721+
 722`--date=raw` shows the date in the internal raw Git format `%s %z` format.
 723+
 724`--date=default` shows timestamps in the original time zone
 725(either committer's or author's).
 726
 727ifdef::git-rev-list[]
 728--header::
 729        Print the contents of the commit in raw-format; each record is
 730        separated with a NUL character.
 731endif::git-rev-list[]
 732
 733--parents::
 734        Print also the parents of the commit (in the form "commit parent...").
 735        Also enables parent rewriting, see 'History Simplification' below.
 736
 737--children::
 738        Print also the children of the commit (in the form "commit child...").
 739        Also enables parent rewriting, see 'History Simplification' below.
 740
 741ifdef::git-rev-list[]
 742--timestamp::
 743        Print the raw commit timestamp.
 744endif::git-rev-list[]
 745
 746--left-right::
 747        Mark which side of a symmetric diff a commit is reachable from.
 748        Commits from the left side are prefixed with `<` and those from
 749        the right with `>`.  If combined with `--boundary`, those
 750        commits are prefixed with `-`.
 751+
 752For example, if you have this topology:
 753+
 754-----------------------------------------------------------------------
 755             y---b---b  branch B
 756            / \ /
 757           /   .
 758          /   / \
 759         o---x---a---a  branch A
 760-----------------------------------------------------------------------
 761+
 762you would get an output like this:
 763+
 764-----------------------------------------------------------------------
 765        $ git rev-list --left-right --boundary --pretty=oneline A...B
 766
 767        >bbbbbbb... 3rd on b
 768        >bbbbbbb... 2nd on b
 769        <aaaaaaa... 3rd on a
 770        <aaaaaaa... 2nd on a
 771        -yyyyyyy... 1st on b
 772        -xxxxxxx... 1st on a
 773-----------------------------------------------------------------------
 774
 775--graph::
 776        Draw a text-based graphical representation of the commit history
 777        on the left hand side of the output.  This may cause extra lines
 778        to be printed in between commits, in order for the graph history
 779        to be drawn properly.
 780+
 781This enables parent rewriting, see 'History Simplification' below.
 782+
 783This implies the `--topo-order` option by default, but the
 784`--date-order` option may also be specified.
 785
 786--show-linear-break[=<barrier>]::
 787        When --graph is not used, all history branches are flattened
 788        which can make it hard to see that the two consecutive commits
 789        do not belong to a linear branch. This option puts a barrier
 790        in between them in that case. If `<barrier>` is specified, it
 791        is the string that will be shown instead of the default one.
 792
 793ifdef::git-rev-list[]
 794--count::
 795        Print a number stating how many commits would have been
 796        listed, and suppress all other output.  When used together
 797        with `--left-right`, instead print the counts for left and
 798        right commits, separated by a tab. When used together with
 799        `--cherry-mark`, omit patch equivalent commits from these
 800        counts and print the count for equivalent commits separated
 801        by a tab.

 805Diff Formatting
 806~~~~~~~~~~~~~~~
 807
 808Listed below are options that control the formatting of diff output.
 809Some of them are specific to linkgit:git-rev-list[1], however other diff
 810options may be given. See linkgit:git-diff-files[1] for more options.
 811
 812-c::
 813        With this option, diff output for a merge commit
 814        shows the differences from each of the parents to the merge result
 815        simultaneously instead of showing pairwise diff between a parent
 816        and the result one at a time. Furthermore, it lists only files
 817        which were modified from all parents.
 818
 819--cc::
 820        This flag implies the `-c` option and further compresses the
 821        patch output by omitting uninteresting hunks whose contents in
 822        the parents have only two variants and the merge result picks
 823        one of them without modification.
 824
 825-m::
 826        This flag makes the merge commits show the full diff like
 827        regular commits; for each merge parent, a separate log entry
 828        and diff is generated. An exception is that only diff against
 829        the first parent is shown when `--first-parent` option is given;
 830        in that case, the output represents the changes the merge
 831        brought _into_ the then-current branch.
 832
 833-r::
 834        Show recursive diffs.
 835
 836-t::
 837        Show the tree objects in the diff output. This implies `-r`.
