Note: the situation described here is completely different from this one.
I have a couple of still-attached screen sessions, but
screen -list produces
% screen -list No Sockets found in /tmp/uscreens/S-jones.
I've tried to send
SIGCHLD signals to the screen process, and I have also killed some of the shells running under them (in the hope that this would cause the kernel to send some signal to these processes). The theory behind all this is that such signals would cause
screen to re-create the appropriate sockets under
/tmp/uscreens. But none of these things worked.
Since the sessions are still attached, is there anything that I can do within each session to have it regenerate the appropriate sockets?
