Make sure you have the screen RPM installed on the remote machine, then
you can run the command in a screen session:
remote-machine> screen -d -m -S SomeIdentifier <command> <args>
Or from ssh on your local machine:
ssh user@remote-host "screen -d -m -S SomeIdentifier <command> <args>"
In the screen command, the "-d -m" means "run the command in a detached
session". The "-S SomeIdentifier" just gives the session an identifiable
name. For example, if I use
-S TestScreen
I'd get something like:
remote-machine> screen -ls
There is a screen on:
7391.TestScreen (Detached)
(other stuff)
Otherwise you'd get something like:
7434.pts-11.prophead (Detached)
(other stuff)
To attach to the detached session, use "screen -r <sessionID>", in the
example case:
remote-machine> screen -r 7391.TestScreen
Once you're attached to it, you can either "CTRL-C" to end the session
or simply detach again by hitting "CTRL-A" followed by the "D" key. See
"man screen" for details.
Note that if you put a space in the session identifier, you MUST enclose
it in quotes so the shell doesn't try to interpret it.
