Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Using tput to save, clear and restore the terminal contents

Very useful for interactive scripts where you would like to return the terminal contents to its original state before the script was run. This would be similar to how vi exits and returns you to your original terminal screen.

Save and clear the terminal contents with:

tput smcup

Execute some commands, then restore the saved terminal contents with:

tput rmcup

What others think

That's brilliant, unfortunately, it doesn't work if your $TERM is screen :(

I know. Lots of stuff breaks with screen. It's a shame really.
