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

gj bud :)

building on this version - i prettified it a bit more:

• formatted results into columns
• added ability to filter by branch name and to show locals
• removed the temp file i/o
• added some switches and usage message
