Screen - Screen Manager for Linux - Exceptionally Useful
Screen is a Window Manager for a Linux SSH Terminal. Similar to having Multiple Desktops and applications, screen provides just that for the Command Line Interface (CLI). As screen runs on the server, if you are downloading a file onto the server etc. or compiling a programme, and your net connection drops, your Screen “session” remains running inside screen, and your applications remain open and active. You can customise screen to provide a Time and Date, along with a Status bar of open applications. This is a MUST HAVE for anyone using a Linux server via the commandline.

Flash Taskbar in PuTTY on Screen Activity
So I've been trying to get this for a while. If I receive an email via pine or pm via irssi it would be nice if PuTTY would flash on the taskbar. Following this page on redbrick got it 1/2 working, in that if the current screen window had activity and PuTTY was minimised, then the taskbar would flash. I wanted it so if any screen window had activity that the taskbar would flash. Anyways after a bit of trial and error here is how I got it:
**Step 1: Putty Config** Terminal -> Bell -> Taskbar/caption indication on bell: Flashing #Might want to save this to the default profile in PuTTY. **Step 2: Screen Config** This is the important step I had overlooked a few times. vi .screenrc vbell off bell_msg '^GBell in window %n' #The ^G (CTRL G) is the key) **Step 3: irssi config** vi .irssi/config settings = { "fe-common/core" = { beep_msg_level = "MSG HILIGHT"; beep_when_away = "yes"; beep_when_window_active = "yes"; bell_beeps = "yes"; }; };
After all this, screen will have to be restarted to take effect. Now, upon getting an email to pine or pm to irssi, PuTTY should flash on the taskbar. Not sure whether this will work for Gome/KDE.
