For those that prefer detachable Screen sessions with multiple windows in shell and want to run instant message chat sessions in CLI without the hassle of Xwindows … CenterIM is for you.
CenterIM is a pretty robust instant messaging client that runs entirely out of your command prompt. Simply sudo apt-get install centerim and you’re ready to go. It takes a little getting used to, but all the files you need are held in your home directory under ~/.centerim . Every contact gets their own folder under .centerim and gets contact-specific chat history logs. The master config files are held in .centerim as well. The first time you run the application, it will show an options window allowing you to configure your preferences. If you delete config file, it will rerun the preferences dialog when you next run the application, however you can access and modify the options by hitting ‘g’ from the main chat window.
CenterIM supports ICQ, Yahoo!, AIM, MSN, IRC, Jabber, LiveJournal, and the Gadu-Gadu IM protocol as well. Anyone familiar with pico, nano or irssi will be right at home with CenterIM.
