Gnu Screen

I'm a big fan Gnu Screen since I work a lot with the console. It multiplexes several shell sessions into one physical console window and it's especially suited for remote server adminstration as it keeps your sessions runing even if you disconnected. It's basically a tabbed shell instance browser.

I use it for setting up several local screens and also a screen to a remote server which is running irssi connected to an internal irc server. By having a remote screen session running I don't have to restart irssi everytime I logon to that server, instead I just reattach to the running screen session and voila irssi is there running.

To install screen, I first install mac ports which downloads, compiles and installs command line, X11 and Aqua based open source software. Install screen by issuing 'sudo port install screen'.

I've mapped the default escape command 'C-a' to 'C-space' instead which much more convenient. So I have C-space mapped for screen, Alt-space for Quicksilver and then Command-Space for  Spotlight.
