How to establish a remote Gnu screen session that you can re-connect to

Long before tabbed terminals existed, people have been using Gnu screen to open many shells in a single text terminal. Combined with ssh, it gives you the ability to have many open shells with a single remote connection using the above options. If you detach with "Ctrl-a d" or if the ssh session is accidentally terminated, all processes running in your remote shells remain undisturbed, ready for you to reconnect. Other useful screen commands are "Ctrl-a c" (open new shell) and "Ctrl-a a" (alternate between shells). Read this quick reference for more screen commands: http://aperiodic.net/screen/quick_reference

Know a better way?

If you can do better, submit your command here.

What others think

Two things, the first, I would suggest -R instead of -r (so that if it cannot find an old session it just creates a new one.

ssh -t remote_host screen -R

And the second thing:

Why do we need the -t option?

Comment by Weboide 200 weeks and 1 day ago

-t forces a terminal to be allocated, otherwise ssh will assume you don't want one since you are only running a command and not opening a shell. Screen needs that terminal or else it won't find anything to attach to and exits.

Thank you for this explanation.

Comment by Weboide 199 weeks and 4 days ago

This can also be used with Byobu this way:

ssh -t remote_host byobu -R
Comment by Weboide 199 weeks and 4 days ago

For that matter, use screen -RR if you figure to expect multiple screen sessions.

Comment by Buzzcp 182 weeks and 1 day ago

I prefere use RD reattach if possible with detach

ssh -t remote_host screen -RD
Comment by starchox 105 weeks and 1 day ago

Can someone explain how to create multiple sessions and run split screen for each session?
