Haha. I was just trying to find a way to broadcast a message stating that something has happened (like an event).
The 'wall' command works fine for the terminals outside screen. 
But if we say I have two regions in screen with two terminals.
And if I execute the 'wall' linux command (not :wall in screen) in one of the terminals then the message is not shown in the second terminal in the second region (in the same screen session). But the message is shown on the terminals that are not running in screen.
I tried to execute 'wall' in a terminal outside screen and the messages is again visible on all terminals not running in screen and not visible on all terminals running in screen. It's strange.
It doesn't matter if I execute 'wall' with root or with my regular user - the message is not shown in either case.
I am using Debian 6 Squeeze with 2.6.39-bpo.2-686-pae kernel from
Thank you for your help!

Works here.. If you wall your users as root or if the wall program is
setuid/gid root, I can't see any reason it shouldn't work.

I'm on debian 5.0 aka ‘lenny’ and the wall program is sgid root.
