This was an interesting Idea, and i have found it on Tips4Linux. Based on: http://tips4linux.com/update-your-twitter-status-from-the-linux-command-line/
T4L: You can easily update your Twitter status from the CLI by using this one simple command:
curl -u user:password -d status=”Your status message” http://twitter.com/statuses/update.xml
where user is your username and password is your Twitter password entered in plaintext. Replace the text Your status message with anything you wish.
