GNU screen – blessing for sys.admins

GNU screen is probably one of the most useful stuffs that makes me tension free and let my laptop to enjoy some hibernation time 🙂

GNU screen is terminal multiplexer, it lets admins to have multiple shell screens simultaneously. The most blessing part of it is, admins can leave anytime with any process running. It will keep doing its given task and then again can be used later from where admin left it. Such a wonderful app, eh?

installation process is just typical.

So like the famous GNU text editor emacs, it uses ctrl+a.

to detach from current window ctrl+a d

to kill current window ctrl+a k

switching between windows ctrl+a n & ctrl+a p

Every screen has an ID.

to get the screen back to work screen -r <screen id>
