Enabling git bash completion on OS X
Bash completion, the magic that allows you to start typing the name of a file, directory, etc. in bash then press TAB to complete it, can be taught new tricks, including knowing about your git repository. But if you’re on a Mac, the magic is not installed by defaut.
If you are running git from MacPorts, you probably don’t have the bash_completion variant installed. You can install it with:
sudo port install git-core +bash_completion
If you do already have git installed without this variant, you’ll probably need to deactivate it first:
sudo port deactivate git-core
Then reinstall with the variants you need:
sudo port install git-core +bash_completion +gitweb +svn +doc
You can then activate completion by adding the following to your
if [ -f /opt/local/etc/bash_completion ]; then . /opt/local/etc/bash_completion fi
