Linux Trick 2: Getting your screen back when it's hosed

Try this:

# cat /bin/cat

Behold! Your terminal looks like garbage. Everything you type looks like you're looking into the Matrix. What do you do?

You type reset. But wait you say, typing reset is too close to typing reboot or shutdown. Your palms start to sweat—especially if you are doing this on a production machine.

Rest assured: You can do it with the confidence that no machine will be rebooted. Go ahead, do it:

# reset

Now your screen is back to normal. This is much better than closing the window and then logging in again, especially if you just went through five machines to SSH to this machine.
