I am trying to get a list of windows from screen in a bash script. if I do "screen -Q windows" with one session then I get no output and an exit status of 1.
If I do "screen -Q windows" with more than one session then I get the
below and an exit status of 1
There are several suitable screens on:
There are several suitable screens on: 7872.pts-21.myhost (Attached)
6685.foobar (Attached)
5391.pts-19.myhost (Attached)
Use -S to specify a session.
If I do "screen -S 6685.foobar -Q windows" then I get no output and an
exit status of 0.
The session "6685.foobar" contains two windows that have been given
titles (C-a ") of win1 and win2.
Should the above work, or am I doing something wrong?
I have Screen version 4.02.01 (GNU) 28-Apr-14 running on Arch Linux
3.16.4-1-ARCH x86_64 GNU/Linux
Thanks,
John
