Top Forums UNIX for Dummies Questions & Answers Help with screen Post 302100505 by Gurth on Wednesday 20th of December 2006 06:58:38 AM

I have been able to come close using "screen" utility.
If i enter the command prompt of the "screen" i can then do:

Code:
at 1# "ls -al"

The problem is that i can't get an escape char from the shell. I need to type
ctrl-a-: to get to the command prompt of the screen utility.

Can i perhaps prefix the

at 1# "ls -al"

with some char sequence to emulate the escape char?
