See linkgit: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 (regular expression). + +--grep='pattern':: + + Limit the commits output to ones with log message that + matches the specified pattern (regular expression). + +-i, --regexp-ignore-case:: + + Match the regexp limiting patterns without regard to letters case. + +-E, --extended-regexp:: + + Consider the limiting patterns to be extended regular expressions + instead of the default basic regular expressions. + +--remove-empty:: + + Stop when a given path disappears from the tree. + +--full-history:: + + Show also parts of history irrelevant to current state of a given + path. This turns off history simplification, which removed merges + which didn't change anything at all at some child. It will still actually + simplify away merges that didn't change anything at all into either + child. + +--no-merges:: + + Do not print commits with more than one parent. + +--first-parent:: + Follow only the first parent commit upon seeing a merge + commit. This option can give a better overview when + viewing the evolution of a particular topic branch, + because merges into a topic branch tend to be only about + adjusting to updated upstream from time to time, and + this option allows you to ignore the individual commits + brought in to your history by such a merge. + +--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. + +--quiet:: + + Don't print anything to standard output. This form + is primarily meant to allow the caller to + test the exit status to see if a range of objects is fully + connected (or not). It is faster than redirecting stdout + to /dev/null as the output does not have to be formatted. + +--cherry-pick:: + + Omit any commit that introduces the same change as + another commit on the "other side" when the set of + commits are limited with symmetric difference. ++ +For example, if you have two branches, `A` and `B`, a usual way +to list all commits on only one side of them is with +`--left-right`, like the example above in the description of +that option. It however shows the commits that were cherry-picked +from the other branch (for example, "3rd on b" may be cherry-picked +from branch A). With this option, such pairs of commits are +excluded from the output. + +-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. + +Cannot be combined with '\--reverse'. +See also linkgit:git-reflog[1]. + +--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. + +ifdef::git-rev-list[] +--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. + +--bisect-vars:: + +This calculates the same as `--bisect`, but outputs text ready +to be eval'ed by the shell. These lines will assign the name of +the midpoint revision to the variable `bisect_rev`, and the +expected number of commits to be tested after `bisect_rev` is +tested to `bisect_nr`, the expected number of commits to be +tested if `bisect_rev` turns out to be good to `bisect_good`, +the expected number of commits to be tested if `bisect_rev` +turns out to be bad to `bisect_bad`, and the number of commits +we are bisecting right now to `bisect_all`. + +--bisect-all:: + +This outputs all the commit objects between the included and excluded +commits, ordered by their distance to the included and excluded +commits. The farthest from them is displayed first. (This is the only +one displayed by `--bisect`.) + +This is useful because it makes it easy to choose a good commit to +test when you want to avoid to test some of them for some reason (they +may not compile for example). + +This option can be used along with `--bisect-vars`, in this case, +after all the sorted commit objects, there will be the same text as if +`--bisect-vars` had been used alone. +endif::git-rev-list[] + +-- + +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. + Cannot be combined with '\--walk-reflogs'. + +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. '--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 + linkgit: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. + +--no-walk:: + + Only show the given revs, but do not traverse their ancestors. + +--do-walk:: + + Overrides a previous --no-walk. |
