]]> About a year ago, I was introduced to the joys of using irssi and screen to access irc servers. Before that time, I'd usually used graphical clients like Colloquy, and I always enjoyed getting Growl notifications when someone mentioned a word or string that I set up as a trigger.

Once I started using irssi in screen, I found that the visual bell in screen didn't get my attention quickly. Luckily, someone in the #slicehost channel let me know about screen's audible bell. You can flip between the visual and audible bell with CTRL-A and then CTRL-G. If you keep repeating that key combination, you'll switch back and forth between the two (with a status update at the bottom left).

You can also set up your visual bell configuration in your .screenrc via some configuration parameters:

vbell [on|off]
vbell_msg [message]
vbellwait sec

]]> One of my favorite (and most used) applications on any Linux machine is screen. Once you fire up a screen session, you can start something and keep it running indefinitely. Even if your internet connection drops or you accidentally close your terminal window, the screen session will remain open on the remote server.

Detaching from a screen session is done by pressing CTRL-A and then d (for detach). However, when I'm on my Mac, CTRL-A and CTRL-E send my cursor to the beginning and end of lines, respectively. Once I launch screen, I lose the CTRL-A functionality because screen thinks I'm trying to send it a command.

Luckily, this can be changed in your ~/.screenrc:

escape ^Ww

With this change, you can press CTRL-W, then press d, and you'll detach from the screen session. For all of the screen options, run man screen on your local machine or review the man page online.
