Thank you, those are good pointers. Though the -Q lastmasg refers to
remote screen session.
I would like to get within the screen session the ID of session, and
then within that session to open a new window.
So far this one works within the session, to open a new window:
screen -x 2488.pts-2.protected -X screen -t newwin
How could I non-interactively get the session name from: screen -X
sessionname?
