Here is a good list of six gnome-terminal commands which you really wont need and you probably won’t ever use them unless out of curiosity (like I did). But sure tell me if you do use them and why in the comments at the bottom of the page.

1. Watching Star-Wars

No, no, no don’t get me wrong there’s nothing wrong with watching Star-Wars but when you can watch a text based version of Episode VI IV New Hope from the terminal it gets a little ridiculous (but it is quite clever).

This is just one of those things where you never know when you might need it, add it to your collection. Once setup it’s quite simple and quick to send an e-mail using the the Gnome-Terminal (or equivalent) in Linux.
