git‐show‐branch − Show branches and their commits



git show−branch [−a|−−all] [−r|−−remotes] [−−topo−order | −−date−order]
                [−−current] [−−color[=<when>] | −−no−color] [−−sparse]
                [−−more=<n> | −−list | −−independent | −−merge−base]
                [−−no−name | −−sha1−name] [−−topics]
                [(<rev> | <glob>)...]
git show−branch (−g|−−reflog)[=<n>[,<base>]] [−−list] [<ref>]




Shows the commit ancestry graph starting from the commits
named with <rev>s or <glob>s (or all refs under refs/heads
and/or refs/tags) semi−visually.

It cannot show more than 29 branches and commits at a time.

It uses showbranch.default multi−valued configuration items
if no <rev> or <glob> is given on the command line.



     <rev>
     Arbitrary extended SHA−1 expression (see
     gitrevisions(7)) that typically names a branch head or
     a tag.

     <glob>
     A glob pattern that matches branch or tag names under
     refs/. For example, if you have many topic branches
     under refs/heads/topic, giving topic/* would show all
     of them.

     −r, −−remotes
     Show the remote−tracking branches.

     −a, −−all
     Show both remote−tracking branches and local branches.

     −−current
     With this option, the command includes the current
     branch to the list of revs to be shown when it is not
     given on the command line.

     −−topo−order
     By default, the branches and their commits are shown in
     reverse chronological 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 commits are ordered according to their commit
     date.

     −−sparse
     By default, the output omits merges that are reachable
     from only one tip being shown. This option makes them
     visible.

     −−more=<n>
     Usually the command stops output upon showing the
     commit that is the common ancestor of all the branches.
     This flag tells the command to go <n> more common
     commits beyond that. When <n> is negative, display only
     the <reference>s given, without showing the commit
     ancestry tree.

     −−list
     Synonym to −−more=−1

     −−merge−base
     Instead of showing the commit list, determine possible
     merge bases for the specified commits. All merge bases
     will be contained in all specified commits. This is
     different from how git‐merge‐base(1) handles the case
     of three or more commits.

     −−independent
     Among the <reference>s given, display only the ones
     that cannot be reached from any other <reference>.

     −−no−name
     Do not show naming strings for each commit.

     −−sha1−name
     Instead of naming the commits using the path to reach
     them from heads (e.g. "master~2" to mean the
     grandparent of "master"), name them with the unique
     prefix of their object names.

     −−topics
     Shows only commits that are NOT on the first branch
     given. This helps track topic branches by hiding any
     commit that is already in the main line of development.
     When given "git show−branch −−topics master topic1
     topic2", this will show the revisions given by "git
     rev−list ^master topic1 topic2"

     −g, −−reflog[=<n>[,<base>]] [<ref>]
     Shows <n> most recent ref−log entries for the given
     ref. If <base> is given, <n> entries going back from
     that entry. <base> can be specified as count or date.









                             ‐3‐


     When no explicit <ref> parameter is given, it defaults
     to the current branch (or HEAD if it is detached).

     −−color[=<when>]
     Color the status sign (one of these: * !  + −) of each
     commit corresponding to the branch it’s in. The value
     must be always (the default), never, or auto.

     −−no−color
     Turn off colored output, even when the configuration
     file gives the default to color output. Same as
     −−color=never.

Note that −−more, −−list, −−independent and −−merge−base
options are mutually exclusive.



Given N <references>, the first N lines are the one−line
description from their commit message. The branch head that
is pointed at by $GIT_DIR/HEAD is prefixed with an asterisk
* character while other heads are prefixed with a !
character.

Following these N lines, one−line log for each commit is
displayed, indented N places. If a commit is on the I−th
branch, the I−th indentation character shows a + sign;
otherwise it shows a space. Merge commits are denoted by a 
sign. Each commit shows a short name that can be used as an
extended SHA−1 to name that commit.

The following example shows three branches, "master",
"fixes" and "mhf":

     $ git show−branch master fixes mhf
     * [master] Add 'git show−branch'.
      ! [fixes] Introduce "reset type" flag to "git reset"
       ! [mhf] Allow "+remote:local" refspec to cause −−force when fetching.
     −−−
       + [mhf] Allow "+remote:local" refspec to cause −−force when fetching.
       + [mhf~1] Use git−octopus when pulling more than one heads.
      +  [fixes] Introduce "reset type" flag to "git reset"
       + [mhf~2] "git fetch −−force".
       + [mhf~3] Use .git/remote/origin, not .git/branches/origin.
       + [mhf~4] Make "git pull" and "git fetch" default to origin
       + [mhf~5] Infamous 'octopus merge'
       + [mhf~6] Retire git−parse−remote.
       + [mhf~7] Multi−head fetch.
       + [mhf~8] Start adding the $GIT_DIR/remotes/ support.
     *++ [master] Add 'git show−branch'.


These three branches all forked from a common commit,
[master], whose commit message is "Add 'git show−branch'".









                             ‐4‐


The "fixes" branch adds one commit "Introduce "reset type"
flag to "git reset"". The "mhf" branch adds many other
commits. The current branch is "master".



If you keep your primary branches immediately under
refs/heads, and topic branches in subdirectories of it,
having the following in the configuration file may help:

     [showbranch]
             default = −−topo−order
             default = heads/*


With this, git show−branch without extra parameters would
show only the primary branches. In addition, if you happen
to be on your topic branch, it is shown as well.

     $ git show−branch −−reflog="10,1 hour ago" −−list master


shows 10 reflog entries going back from the tip as of 1 hour
ago. Without −−list, the output also shows how these tips
are topologically related with each other.
