Man page 1 : git-rev-list

Using these options, git-rev-list(1) will act similar to the more specialized family of commit log tools: git-log(1), git-show(1), and git-whatchanged(1)

--pretty[=<format>], --format=<format>
    Pretty-print the contents of the commit logs in a given format, where <format> can be one of oneline, short, medium, full, fuller, email, raw and format:<string>. See the "PRETTY FORMATS" section for some additional details for each format. When omitted, the format defaults to medium.

Note: you can specify the default pretty format in the repository configuration (see git-config(1)).

--abbrev-commit
    Instead of showing the full 40-byte hexadecimal commit object name, show only a partial prefix. Non default number of digits can be specified with "--abbrev=<n>" (which also modifies diff output, if it is displayed).

This should make "--pretty=oneline" a whole lot more readable for people using 80-column terminals.

--oneline
    This is a shorthand for "--pretty=oneline --abbrev-commit" used together.

--encoding[=<encoding>]
    The commit objects record the encoding used for the log message in their encoding header; this option can be used to tell the command to re-code the commit log message in the encoding preferred by the user. For non plumbing commands this defaults to UTF-8.

--no-notes, --show-notes[=<ref>]
    Show the notes (see git-notes(1)) that annotate the commit, when showing the commit log message. This is the default for git log, git show and git whatchanged commands when there is no --pretty, --format nor --oneline option is given on the command line.

With an optional argument, add this ref to the list of notes. The ref is taken to be in refs/notes/ if it is not qualified.

--[no-]standard-notes
    Enable or disable populating the notes ref list from the core.notesRef and notes.displayRef variables (or corresponding environment overrides). Enabled by default. See git-config(1).

--relative-date
    Synonym for --date=relative.

--date={relative,local,default,iso,rfc,short,raw}
    Only takes effect for dates shown in human-readable format, such as when using "--pretty". log.date config variable sets a default value for log command(cqs --date option.

--date=relative shows dates relative to the current time, e.g. "2 hours ago".

--date=local shows timestamps in user(cqs local timezone.

--date=iso (or --date=iso8601) shows timestamps in ISO 8601 format.

--date=rfc (or --date=rfc2822) shows timestamps in RFC 2822 format, often found in E-mail messages.

--date=short shows only date but not time, in YYYY-MM-DD format.

--date=raw shows the date in the internal raw git format %s %z format.

--date=default shows timestamps in the original timezone (either committer(cqs or author(cqs).

--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. Also enables parent rewriting, see History Simplification below.

--children
    Print the children of the commit. Also enables parent rewriting, see History Simplification below.

--timestamp
    Print the raw commit timestamp.

--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 like 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

.

--graph
    Draw a text-based graphical representation of the commit history on the left hand side of the output. This may cause extra lines to be printed in between commits, in order for the graph history to be drawn properly.

This implies the --topo-order option by default, but the --date-order option may also be specified.

--count
    Print a number stating how many commits would have been listed, and suppress all other output. When used together with --left-right, instead print the counts for left and right commits, separated by a tab.

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).

--all-match
    Limit the commits output to ones that match all given --grep, --author and --committer instead of ones that match at least one.

-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.

-F, --fixed-strings
    Consider the limiting patterns to be fixed strings (don(cqt interpret pattern as a regular expression).

--remove-empty
    Stop when a given path disappears from the tree.

--merges
    Print only merge commits.

--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 ^ prefix (or lack thereof) for all following revision specifiers, up to the next --not.

--all
    Pretend as if all the refs in refs/ are listed on the command line as <commit>.

--branches[=pattern]
    Pretend as if all the refs in refs/heads are listed on the command line as <commit>. If pattern is given, limit branches to ones matching given shell glob. If pattern lacks ?, , or \fI[\fR, \fI/\fR at the end is implied.

--tags[=pattern]
    Pretend as if all the refs in refs/tags are listed on the command line as <commit>. If pattern is given, limit tags to ones matching given shell glob. If pattern lacks ?, , or \fI[\fR, \fI/\fR at the end is implied.

--remotes[=pattern]
    Pretend as if all the refs in refs/remotes are listed on the command line as <commit>. If `pattern`is given, limit remote tracking branches to ones matching given shell glob. If pattern lacks ?, , or \fI[\fR, \fI/\fR at the end is implied.

--glob=glob-pattern
    Pretend as if all the refs matching shell glob glob-pattern are listed on the command line as <commit>. Leading refs/, is automatically prepended if missing. If pattern lacks ?, , or \fI[\fR, \fI/\fR at the end is implied.

--stdin
    In addition to the <commit> listed on the command line, read them from the standard input. If a -- separator is seen, stop reading commits and start reading paths to limit the result.

--quiet
    Don(cqt 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, ^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, \\fR notation is used in the output. When the starting commit is specified as \\fR, output also uses \\fR notation instead. Under --pretty=oneline, the commit message is prefixed with this information on the same line. This option cannot be combined with --reverse. See also git-reflog(1).

--merge
    After a failed merge, show refs that touch files having a conflict and don(cqt exist on all heads to merge.

--boundary
    Output uninteresting commits at the boundary, which are usually not shown.

Sometimes you are only interested in parts of the history, for example the commits modifying a particular <path>. But there are two parts of History Simplification, one part is selecting the commits and the other is how to do it, as there are various strategies to simplify the history.

The following options select the commits to be shown:

<paths>
    Commits modifying the given <paths> are selected.

--simplify-by-decoration
    Commits that are referred by some branch or tag are selected.

Note that extra commits can be shown to give a meaningful history.

The following options affect the way the simplification is performed:

Default mode
    Simplifies the history to the simplest history explaining the final state of the tree. Simplest because it prunes some side branches if the end result is the same (i.e. merging branches with the same content)

--full-history
    As the default mode but does not prune some history.

--dense
    Only the selected commits are shown, plus some to have a meaningful history.

--sparse
    All commits in the simplified history are shown.

--simplify-merges
    Additional option to --full-history to remove some needless merges from the resulting history, as there are no selected commits contributing to this merge.

--ancestry-path
    When given a range of commits to display (e.g. commit1..commit2 or commit2 ^commit1), only display commits that exist directly on the ancestry chain between the commit1 and commit2, i.e. commits that are both descendants of commit1, and ancestors of commit2.

A more detailed explanation follows.

Suppose you specified foo as the <paths>. We shall call commits that modify foo !TREESAME, and the rest TREESAME. (In a diff filtered for foo, they look different and equal, respectively.)

In the following, we will always refer to the same example history to illustrate the differences between simplification settings. We assume that you are filtering for a file foo in this commit graph:


    .

         .-A---M---N---O---P
         /     /   /   /   /
        I     B   C   D   E
         \   /   /   /   /
          `-------------\*(Aq

.



The horizontal line of history AP is taken to be the first parent of each merge. The commits are:


    .ie n \ \h'-04'\h'+03'\c .

2.3 . I is the initial commit, in which foo exists with contents "asdf", and a file quux exists with contents "quux". Initial commits are compared to an empty tree, so I is !TREESAME.


    .ie n \ \h'-04'\h'+03'\c .

2.3 . In A, foo contains just "foo".


    .ie n \ \h'-04'\h'+03'\c .

2.3 . B contains the same change as A. Its merge M is trivial and hence TREESAME to all parents.


    .ie n \ \h'-04'\h'+03'\c .

2.3 . C does not change foo, but its merge N changes it to "foobar", so it is not TREESAME to any parent.


    .ie n \ \h'-04'\h'+03'\c .

2.3 . D sets foo to "baz". Its merge O combines the strings from N and D to "foobarbaz"; i.e., it is not TREESAME to any parent.


    .ie n \ \h'-04'\h'+03'\c .

2.3 . E changes quux to "xyzzy", and its merge P combines the strings to "quux xyzzy". Despite appearing interesting, P is TREESAME to all parents.

rev-list walks backwards through history, including or excluding commits based on whether --full-history and/or parent rewriting (via --parents or --children) are used. The following settings are available.

Default mode
    Commits are included if they are not TREESAME to any parent (though this can be changed, see --sparse below). If the commit was a merge, and it was TREESAME to one parent, follow only that parent. (Even if there are several TREESAME parents, follow only one of them.) Otherwise, follow all parents.

This results in:


    .

         .-A---N---O
         /     /   /
        I---------D

.

Note how the rule to only follow the TREESAME parent, if one is available, removed B from consideration entirely. C was considered via N, but is TREESAME. Root commits are compared to an empty tree, so I is !TREESAME.

Parent/child relations are only visible with --parents, but that does not affect the commits selected in default mode, so we have shown the parent lines.

--full-history without parent rewriting
    This mode differs from the default in one point: always follow all parents of a merge, even if it is TREESAME to one of them. Even if more than one side of the merge has commits that are included, this does not imply that the merge itself is! In the example, we get


    .

       I  A  B  N  D  O

.

P and M were excluded because they are TREESAME to a parent. E, C and B were all walked, but only B was !TREESAME, so the others do not appear.

Note that without parent rewriting, it is not really possible to talk about the parent/child relationships between the commits, so we show them disconnected.

--full-history with parent rewriting
    Ordinary commits are only included if they are !TREESAME (though this can be changed, see --sparse below).

Merges are always included. However, their parent list is rewritten: Along each parent, prune away commits that are not included themselves. This results in


    .

         .-A---M---N---O---P
         /     /   /   /   /
        I     B   /   D   /
         \   /   /   /   /
          `-------------\*(Aq

.

Compare to --full-history without rewriting above. Note that E was pruned away because it is TREESAME, but the parent list of P was rewritten to contain E\*(Aqs parent I. The same happened for C and N. Note also that P was included despite being TREESAME.

In addition to the above settings, you can change whether TREESAME affects inclusion:

--dense
    Commits that are walked are included if they are not TREESAME to any parent.

--sparse
    All commits that are walked are included.

Note that without --full-history, this still simplifies merges: if one of the parents is TREESAME, we follow only that one, so the other sides of the merge are never walked.

--simplify-merges
    First, build a history graph in the same way that --full-history with parent rewriting does (see above).

Then simplify each commit (oqC` to its replacement C(cq in the final history according to the following rules:


    .ie n \ \h'-04'\h'+03'\c .

2.3 . Set (oqC(cq` to C.


    .ie n \ \h'-04'\h'+03'\c .

2.3 . Replace each parent (oqP` of C(cq with its simplification (oqP(cq`. In the process, drop parents that are ancestors of other parents, and remove duplicates.


    .ie n \ \h'-04'\h'+03'\c .

2.3 . If after this parent rewriting, (oqC(cq` is a root or merge commit (has zero or >1 parents), a boundary commit, or !TREESAME, it remains. Otherwise, it is replaced with its only parent.

The effect of this is best shown by way of comparing to --full-history with parent rewriting. The example turns into:


    .

         .-A---M---N---O
         /     /       /
        I     B       D
         \   /       /
          `---------\*(Aq

.

Note the major differences in N and P over --full-history:


    .ie n \ \h'-04'\h'+03'\c .

2.3 . N\*(Aqs parent list had I removed, because it is an ancestor of the other parent M. Still, N remained because it is !TREESAME.


    .ie n \ \h'-04'\h'+03'\c .

2.3 . P\*(Aqs parent list similarly had I removed. P was then removed completely, because it had one parent and is TREESAME.

Finally, there is a fifth simplification mode available:

--ancestry-path
    Limit the displayed commits to those directly on the ancestry chain between the "from" and "to" commits in the given commit range. I.e. only display commits that are ancestor of the "to" commit, and descendants of the "from" commit.

As an example use case, consider the following commit history:


    .

           D---E-------F
           /     \       \
          B---C---G---H---I---J
         /                     \
        A-------K---------------L--M

.

A regular D..M computes the set of commits that are ancestors of M, but excludes the ones that are ancestors of D. This is useful to see what happened to the history leading to M since D, in the sense that "what does M have that did not exist in D". The result in this example would be all the commits, except A and B (and D itself, of course).

When we want to find out what commits in M are contaminated with the bug introduced by D and need fixing, however, we might want to view only the subset of D..M that are actually descendants of D, i.e. excluding C and K. This is exactly what the --ancestry-path option does. Applied to the D..M range, it results in:


    .

               E-------F
                 \       \
                  G---H---I---J
                               \
                                L--M

.



The --simplify-by-decoration option allows you to view only the big picture of the topology of the history, by omitting commits that are not referenced by tags. Commits are marked as !TREESAME (in other words, kept after history simplification rules described above) if (1) they are referenced by tags, or (2) they change the contents of the paths given on the command line. All other commits are marked as TREESAME (subject to be simplified away).

--bisect
    Limit output to the one commit object which is roughly halfway between included and excluded commits. Note that the bad bisection ref refs/bisect/bad is added to the included commits (if it exists) and the good bisection refs refs/bisect/good-* are added to the excluded commits (if they exist). Thus, supposing there are no refs in refs/bisect/, 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 \*(Aqmidpoint(cqs until the commit chain is of length one.

--bisect-vars
    This calculates the same as --bisect, except that refs in refs/bisect/ are not used, and except that this outputs text ready to be eval(cqed 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. Refs in refs/bisect/ are not used. 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.

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.

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 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.
