Indeed, it is really basic. I guess I could see value in aliasing that to save typing. In my case, I have a "Screen" menu in fvwm with menu entries like this:
That gives me shells in the directories I'm likely to be working from, and starts an irb session in another shell.
I guess this is only newsworthy if you're not the type to customize your environment to your liking. Well, that and the fact that gnu screen is somewhat difficult to learn and researching it is a pain because "screen" is such a poor, generic name for a project.
I'd love to see this turn into a thread of neat things that can be done with gnu screen.
ssh yourserver -t "screen -D -RR"
doesnt't allow you use screen from multiple xterms
if you use
ssh -t yourserver screen -S main -xRR -p windowname -q
as was used in the post, you get to use, multiple xterms all connecting to the same session.
And, as thras pointed out, it's needlessly complicated. All you need to do is:
ssh yourserver -t "screen -D -RR"
And you'll have a new screen session, or reattach to your old screen session, however you left it set up.
If you're on a mac and you want to set up a different background colour for each server, check out my tutorial at: http://www.swombat.com/setting-up-terminalapp-with-tr-0
