How to Post to Notification Center From a Shell Script
Posting to Notification Center center from a shell script is a great way to let yourself know that a potentially long process has completed. Luckily, it's just one line:
osascript -e 'display notification "Holy **** it worked!" with title "The Main Thread"'
An aside: I'm still trying to figure out how best to include both short posts and long-form articles on this site. Consider this an experiment.
