[blah]$ screen -ls There are screens on: 16517.pts-0.blah (01/28/2012 01:55:32 PM) (Detached) 4345.pts-1.blah (01/27/2012 11:22:48 AM) (Attached) 2 Sockets in /var/run/screen/S-blahblah.
Got 2 questions
1) What's the difference between attached and detached screen
2) Can you kill attached and detached screen and how do you do it? (I killed attached screen with screen -X -S id kill before but I don't think it works on detached one)
