Show git ahead and behind info for all branches, including remotes

On a github project you can go to a /branches page and se pretty graphs like this one that for each branch show how far behind and how far ahead each branch is with respect to master.

git branch ahead behind

Is there a command line tool that does something similar? Something that works with remotes as well? For example,

git branch -v -v


is close to what I am looking for, but only works for local branches.

Answer

I've been curious about this as well, so i just whipped up a git branch-status script that gives this information using git for-each-ref

#!/bin/bash
# by http://github.com/jehiah
# this prints out some branch status (similar to the '... ahead' info you get from git status)

# example:
# $ git branch-status
# dns_check (ahead 1) | (behind 112) origin/master
# master (ahead 2) | (behind 0) origin/master

git for-each-ref --format="%(refname:short) %(upstream:short)" refs/heads | \
while read local remote
do
    [ -z "$remote" ] && continue
    git rev-list --left-right ${local}...${remote} -- 2>/dev/null >/tmp/git_upstream_status_delta || continue
    LEFT_AHEAD=$(grep -c '^<' /tmp/git_upstream_status_delta)
    RIGHT_AHEAD=$(grep -c '^>' /tmp/git_upstream_status_delta)
    echo "$local (ahead $LEFT_AHEAD) | (behind $RIGHT_AHEAD) $remote"
done

Usage:

$ git branch-status
dns_check (ahead 1) | (behind 112) origin/master
master (ahead 2) | (behind 0) origin/master
