screen -Q windows

[John Lane]

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
