So I came across this little article a few days ago and I thought It'd be a useful share. The way this utility works is that you just type in cheat commandname and it'll bring back all the different ways you can use that command. This is a really nice and easy way to get information on a command you've forgotten how to use or just don't know enough about. It's also super easy to install / setup and I highly reccomend it for any linux user out there.
