Two Linux Twitter Clients: Twidge and Tircd
Most Twitter and other micro-blogging clients use the same interface as Twitter.com, but two new free software clients make Twitter easy to use from the command-line or an IRC client.
Twidge lets you send and receive Twitter or Identi.ca updates from the command-line. Although micro-blogging from the command-line may not appeal to you, the command-line makes it easy to fiddle with Twitter, and Twidge works well in shell scripts. For example, you can automate sending updates or filter out unwanted updates from your friends.
Debian and Ubuntu Jaunty users can install the "twidge" package. Other users should download the static executable from Twidge's download page, run bunzip2 on the file, copy it to /usr/local/bin/twidge, and make it executable with the following command: chmod +x /usr/local/bin/twidge. You also need to install your distribution's cURL package.
At the command-line, setup Twidge by typing the following command: twidge setup. Tell it your username and password. You only need to run this command once.
