Description
======================

Find and delete old git branches that are no longer needed.

Usage
======================

Clone the repo and add to your path (just for ease of use):

    git clone git://gist.github.com/2891516.git gist-2891516
    cd gist-2891516
    export PATH="$PATH:$(pwd)"

Now go to your project. 

    # list branches that have been merged to the current branch
    git old-branches

    # list branches that have been merged to the remote:
    git old-branches github/master

    # format branch delete commands according to user:
    git old-branches github/master | format_branch_deletes

Example output:

    $ git old-branches | format_branch_deletes
    # schiang@comverge.com

      git branch -d remove_new_relic  # 301a52b (5 hours ago) <schiang@comverge.com>
      git branch -d something         # 301a52b (5 hours ago) <schiang@comverge.com>

    $ git old-branches github/master | format_branch_deletes
    # schiang@comverge.com

      git push github :30434977_fix_the_clock    # a262408 (3 weeks ago) <schiang@comverge.com>
      git push github :add_non_existant_methods  # f47c5c9 (10 days ago) <schiang@comverge.com>
      git push github :manual_requires           # c9bcc3f (3 weeks ago) <schiang@comverge.com>
      git push github :unnecessary_fsr           # 54f4eb4 (9 days ago) <schiang@comverge.com>

The idea is that you can check the delete commands and execute as needed. Note
that once the remote branches are deleted your teammates may have to prune the
deleted branches from their local copies:

    # use --dry-run option first as a precaution
    git remote prune github
