You can easily update your Twitter status from the command line using cURL. The Tech-Recipes blog posted this handy command line hack:
With cURL installed, you can post to Twitter from the terminal window by using the following syntax:
curl -u yourusername:yourpassword -d status="Your Message Here" http://twitter.com/statuses/update.xml
You will receive a response containing the XML coding for your post which acts as a confirmation that your post was submitted.
Consider this: instant messaging is the new talk (phone for my VMS peeps) and Twitter is the new finger. It’s nice to see at least one of these handy communication tools make its way back to the command line.
