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.

creates a bash function to remove certain lines from SSH known_hosts file

the addition of ".bk" to the regular "pie" idiom makes perl create a backup of every file with the extension ".bk", in case it b0rks something and you want it back
