tw is a tiny node script that I often use to avoid switching to a browser when a Twitter status link is mentioned. It was written a long time ago, is ugly, but does the job.
What does it do?
$ tw -h Usage: tw <tweet url | tweet id> -h show help -u <nick> user's tweets -s <search term> search tweets -i <status id | status url> show status
Really, that's it.
