Git Bash Auto-Completion on Mac

Your OS X version of Git may not come with the Git Bash autocompletion scripts. You can add them as follows.

1. Download the script to your home folder.

curl https://raw.githubusercontent.com/git/git/master/contrib/completion/git-completion.bash 
\ -o ~/git-completion.bash

2. Add the following to your ~/.bash_profile:

if [ -f ~/.git-completion.bash ]; then
    source ~/.git-completion.bash
fi
