Thanks, Andrew. My question is: specifically when attaching to a detached session, is there any difference between using `screen -r` and `screen -x`?
For example, suppose I have a detached session called "foo", which I want to attach to. Is there any reason to prefer: screen -r foo To: screen -x foo The reason I'm asking is because I'm writing a script to attach to a screen session by name, and I was wondering if it's worth checking if the session is attached and using screen -r in that case, because if there's no difference, I'd just use screen -x, since it attaches to the session whether it's detached or not. Hope my question is clear... D.
