[ \-- <paths>... ] + +DESCRIPTION +----------- + +Lists commit objects in reverse chronological order starting at the +given commit(s), taking ancestry relationship into account. This is +useful to produce human-readable log output. + +Commits which are stated with a preceding '{caret}' cause listing to +stop at that point. Their parents are implied. Thus the following +command: + +----------------------------------------------------------------------- + $ git-rev-list foo bar ^baz +----------------------------------------------------------------------- + +means "list all the commits which are included in 'foo' and 'bar', but +not in 'baz'". + +A special notation "'<commit1>'..'<commit2>'" can be used as a +short-hand for "{caret}'<commit1>' '<commit2>'". For example, either of +the following may be used interchangeably: + +----------------------------------------------------------------------- + $ git-rev-list origin..HEAD + $ git-rev-list HEAD ^origin +----------------------------------------------------------------------- + +Another special notation is "'<commit1>'...'<commit2>'" which is useful +for merges. The resulting set of commits is the symmetric difference +between the two operands. The following two commands are equivalent: + +----------------------------------------------------------------------- + $ git-rev-list A B --not $(git-merge-base --all A B) + $ git-rev-list A...B +----------------------------------------------------------------------- + +gitlink:git-rev-list[1] is a very essential git program, since it +provides the ability to build and traverse commit ancestry graphs. For +this reason, it has a lot of different options that enables it to be +used by commands as different as gitlink:git-bisect[1] and +gitlink:git-repack[1]. + +OPTIONS +------- + +Commit Formatting +~~~~~~~~~~~~~~~~~ + +Using these options, gitlink:git-rev-list[1] will act similar to the +more specialized family of commit log tools: gitlink:git-log[1], +gitlink:git-show[1], and gitlink:git-whatchanged[1] + +include::pretty-formats.txt[] + +--relative-date:: + + Show dates relative to the current time, e.g. "2 hours ago". + Only takes effect for dates shown in human-readable format, such + as when using "--pretty". + +--header:: + + Print the contents of the commit in raw-format; each record is + separated with a NUL character. + +--parents:: + + Print the parents of the commit. + +--left-right:: + + Mark which side of a symmetric diff a commit is reachable from. + Commits from the left side are prefixed with `<` and those from + the right with `>`. If combined with `--boundary`, those + commits are prefixed with `-`. ++ +For example, if you have this topology: ++ +----------------------------------------------------------------------- + y---b---b branch B + / \ / + / . + / / \ + o---x---a---a branch A +----------------------------------------------------------------------- ++ +you would get an output line this: ++ +----------------------------------------------------------------------- + $ git rev-list --left-right --boundary --pretty=oneline A...B + + >bbbbbbb... 3rd on b + >bbbbbbb... 2nd on b + <aaaaaaa... 3rd on a + <aaaaaaa... 2nd on a + -yyyyyyy... 1st on b + -xxxxxxx... 1st on a +----------------------------------------------------------------------- + +Diff Formatting +~~~~~~~~~~~~~~~ + +Below are listed options that control the formatting of diff output. +Some of them are specific to gitlink:git-rev-list[1], however other diff +options may be given. See gitlink:git-diff-files[1] for more options. + +-c:: + + This flag changes the way a merge commit is displayed. It shows + the differences from each of the parents to the merge result + simultaneously instead of showing pairwise diff between a parent + and the result one at a time. Furthermore, it lists only files + which were modified from all parents. + +--cc:: + + This flag implies the '-c' options and further compresses the + patch output by omitting hunks that show differences from only + one parent, or show the same change from all but one parent for + an Octopus merge. + +-r:: + + Show recursive diffs. + +-t:: + + Show the tree objects in the diff output. This implies '-r'. + +Commit Limiting +~~~~~~~~~~~~~~~ + +Besides specifying a range of commits that should be listed using the +special notations explained in the description, additional commit +limiting may be applied. + +-- + +-n 'number', --max-count='number':: + + Limit the number of commits output. + +--skip='number':: + + Skip 'number' commits before starting to show the commit output. + +--since='date', --after='date':: + + Show commits more recent than a specific date. + +--until='date', --before='date':: + + Show commits older than a specific date. + +--max-age='timestamp', --min-age='timestamp':: + + Limit the commits output to specified time range. + +--author='pattern', --committer='pattern':: + + Limit the commits output to ones with author/committer + header lines that match the specified pattern. + +--grep='pattern':: + + Limit the commits output to ones with log message that + matches the specified pattern. + +--remove-empty:: + + Stop when a given path disappears from the tree. + +--no-merges:: + + Do not print commits with more than one parent. + +--not:: + + Reverses the meaning of the '{caret}' prefix (or lack thereof) + for all following revision specifiers, up to the next '--not'. + +--all:: + + Pretend as if all the refs in `$GIT_DIR/refs/` are listed on the + command line as '<commit>'. + +--stdin:: + + In addition to the '<commit>' listed on the command + line, read them from the standard input. + +-g, --walk-reflogs:: + + Instead of walking the commit ancestry chain, walk + reflog entries from the most recent one to older ones. + When this option is used you cannot specify commits to + exclude (that is, '{caret}commit', 'commit1..commit2', + nor 'commit1...commit2' notations cannot be used). ++ +With '\--pretty' format other than oneline (for obvious reasons), +this causes the output to have two extra lines of information +taken from the reflog. By default, 'commit@{Nth}' notation is +used in the output. When the starting commit is specified as +'commit@{now}', output also uses 'commit@{timestamp}' notation +instead. Under '\--pretty=oneline', the commit message is +prefixed with this information on the same line. + +--merge:: + + After a failed merge, show refs that touch files having a + conflict and don't exist on all heads to merge. + +--boundary:: + + Output uninteresting commits at the boundary, which are usually + not shown. + +--dense, --sparse:: + +When optional paths are given, the default behaviour ('--dense') is to +only output commits that changes at least one of them, and also ignore +merges that do not touch the given paths. + +Use the '--sparse' flag to makes the command output all eligible commits +(still subject to count and age limitation), but apply merge +simplification nevertheless. + +--bisect:: + +Limit output to the one commit object which is roughly halfway between +the included and excluded commits. Thus, if + +----------------------------------------------------------------------- + $ git-rev-list --bisect foo ^bar ^baz +----------------------------------------------------------------------- + +outputs 'midpoint', the output of the two commands + +----------------------------------------------------------------------- + $ git-rev-list foo ^midpoint + $ git-rev-list midpoint ^bar ^baz +----------------------------------------------------------------------- + +would be of roughly the same length. Finding the change which +introduces a regression is thus reduced to a binary search: repeatedly +generate and test new 'midpoint's until the commit chain is of length +one. + +-- + +Commit Ordering +~~~~~~~~~~~~~~~ + +By default, the commits are shown in reverse chronological order. + +--topo-order:: + + This option makes them appear in topological order (i.e. + descendant commits are shown before their parents). + +--date-order:: + + This option is similar to '--topo-order' in the sense that no + parent comes before all of its children, but otherwise things + are still ordered in the commit timestamp order. + +--reverse:: + + Output the commits in reverse order. + +Object Traversal +~~~~~~~~~~~~~~~~ + +These options are mostly targeted for packing of git repositories. + +--objects:: + + Print the object IDs of any object referenced by the listed + commits. 'git-rev-list --objects foo ^bar' thus means "send me + all object IDs which I need to download if I have the commit + object 'bar', but not 'foo'". + +--objects-edge:: + + Similar to '--objects', but also print the IDs of excluded + commits prefixed with a "-" character. This is used by + gitlink:git-pack-objects[1] to build "thin" pack, which records + objects in deltified form based on objects contained in these + excluded commits to reduce network traffic. + +--unpacked:: + + Only useful with '--objects'; print the object IDs that are not + in packs. + +Author +------ +Written by Linus Torvalds <torvalds@osdl.org> + +Documentation +-------------- +Documentation by David Greaves, Junio C Hamano, Jonas Fonseca +and the git-list <git@vger.kernel.org>. + +GIT +--- +Part of the gitlink:git[7] suite |
