I often want to post the same status message in Pidgin and Twitter. I wrote simple bash script to accomplish this.
One can download the script from here: http://www.spsneo.com/scripts/poststatus.tar.gz
How to use it -
1) Change the permission of the file to make it executable:
chmod +x poststatus
2) Then execute the file with the status message as the argument:
./poststatus "Status Message goes here in quotes"
3) The script will first post the status message in your pidgin and will then ask whether you want to post it on twitter. If you say yes, the script asks you for your twitter username and password.
Start using the script and send me feedback to improve it.
