I have a screen session running on my local machine:

~/test@example.com$screen -S pair

Then, turn on multiuser:

ctrl-a:multiuser on

Finally, allow the user pair to connect to the session:

ctrl-a:acladd pair

So far so good. A remote user can log into the machine as pair and connect to the session:

~/$ssh pair@example.io
pair@example~/$screen -x test/pair

But, if I open a split:


The user pair cannot see the split.

Is it possible to have multiple splits open in a shared session?

The split is done in the screen client, not in the screen session itself. pair may split his screen any way he wants, independent of your split.

  • Is it possible to create a split that anyone in the session can see?

  • I believe tmux can do that, as it separates the notions of sessions, windows and panes.

  • Thanks @katti! I actually use tmux all the time (though iterm2) but I didn't think it supported multiuser as well as screen. Do you know if it's possible to have 2 users on the same system share a session with tmux?

Turns out screen now has a layout facility that will keep track of splits. In order for the pair to see the current layout just save it as the default:

ctrl-a:layout save default
