The following instructions make it easy to post to Twitter and Jaiku from the command line. The instructions were copied from the article "Ubuntu Unleashed: Howto Twitter From the Command Line in Ubuntu!" [ubuntu-unleashed.com] and modified to post via Rorbuilder's ProjectX API.

sudo apt-get install curl

sudo gedit /usr/bin/jaitwit

Now Paste this in gEdit and simply replace "YourUsername" with your username and "YourPassword" with your twitter passwd, then replace the Jaiku variables (YourUsername, YourPassword, YourCity, YourAccessKey) and ctrl-s to save, then alt-F4 to exit!
