Re: Identifier matching in the at command

[Artur Skonecki]

The development version of GNU Screen has -Q flag which may be used
to query results of some commands.  Also there is -X flag for sending
arbitrary commands to a session, e.g. "screen -p 1 -Q title" will yield
the title of window 1.  Unfortunately, sending commands to every window
separately is much slower than using "at" command.

If you are willing to compile Screen on your own you might as well
install screen-session https://github.com/skoneka/screen-session/downloads
and grep "screen-session dump" output for window titles.
