git-show-branch(1)


NAME

   git-show-branch - Show branches and their commits

SYNOPSIS

   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>]

DESCRIPTION

   Shows the commit ancestry graph starting from the commits named with
   <rev>s or <globs>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.

OPTIONS

   <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. 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.

OUTPUT

   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'". 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".

EXAMPLE

   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.
