Here’s a little tip I use all the time, but have yet to commit to the blogosphere. If you’re trying to work on the Terminal command line in 10.6 or 10.5, it’s annoying to be prompted for your password to sudo every 5 minutes, and it gets confusing who’s running what commands. If you just type

sudo /bin/bash

and authenticate once, you’ll get a command prompt as root, without having to auth every few minutes. Just. Remember. To. Log. Out.
