Wow, thanks, lajos. I'm experimenting with screen to see how it
works.
I notice that if I ask screen for the processes it's detached from
(using screen -list) I see a list of processes that seem to be on my
local machine, even though they are executing on the remote system.
Perhaps it's a stupid question, but turning my local system off
wouldn't kill the execution I started remotely, would it? It's not
"dependent" on the local process still?
