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
