[[--] <path>...] DESCRIPTION ----------- -List commits that are reachable by following the `parent` links from the -given commit(s), but exclude commits that are reachable from the one(s) -given with a '{caret}' in front of them. The output is given in reverse -chronological order by default. - -You can think of this as a set operation. Commits given on the command -line form a set of commits that are reachable from any of them, and then -commits reachable from any of the ones given with '{caret}' in front are -subtracted from that set. The remaining commits are what comes out in the -command's output. Various other options and paths parameters can be used -to further limit the result. - -Thus, the following command: - ------------------------------------------------------------------------ - $ git rev-list foo bar ^baz ------------------------------------------------------------------------ - -means "list all the commits which are reachable from 'foo' or 'bar', but -not from '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 ------------------------------------------------------------------------ +:git-rev-list: 1 +include::rev-list-description.txt[] 'rev-list' is a very essential Git command, since it provides the ability to build and traverse commit ancestry graphs.
