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.

yeah it is, but at least it centers your cursor, I made it up for use in one of my scripts, was the best I found at the time to center cursor on screen

However, I think that for own purposes all commands do jobs :)

Decent for a working one-liner I guess, this looks like a good candidate for being placed in one's .bashrc file. There you could make it readable by actually using variables.
