OS X: Make a sound when commands finish running

If you are like me, you might get distracted while waiting for your unit tests to complete, and only return to your IDE several minutes later.

On OS X, there is a nifty say command that makes your Mac say anything you want using text-to-speech. By appending it at the end of a long-running command, you can get a voice notification when it completes.

In the example below, your Mac will say “Unit tests completed” when they are done running:

python manage.py test; say "Unit tests completed"
