I run a combination of screen and autossh to open terminal emulators on a
remote box R. Occasionally, be by accident or by design, my local box L
gets rebooted. When this happens, on bringing L up again I would like to
retrieve my screen/autossh terminal emulators running on R. This is easy
enough: First I ssh from L into R; in this ssh session I do screen -list to
obtain the list of detached screens in R; I finally reattach to the screen
session I want by means of exec screen -x id, where id is the id of the
target screen session, as printed out by screen -list.
Although this recovers my detached session all right, the problem is that
in RI will now have two screen sessions for each screen session I reattach
to. Is there a simple way to reattach without incurring in this drawback?
