One comment is that 'screen -X' will be disabled if you have set a
screen password.


Here are some of my annotations:

$ longrunningapp.sh; screen -X focus <thiswindownumber>

You might want to mention that you can achieve similar functionality
through the monitoring commands C-A _, and C-A M.

--
Environmentvariable $STY
...
Checking if you are inside a screen session
$ if [ -n "$STY" ]; then echo 'We are inside screen'; fi

Also, you could mention that screen sets TERM to "screen".

I've been wanting to develop a howto for using hardstatus logs and
something like newsyslog/logrotate to keep accounting information of all
of my buffers; thanks for adding some more examples to the list of
things to do with 'hardcopy'.

Running a screen window dia-show

I could see this as benefiting from a keybinding and/or a way to quickly
pass in a list of window numbers to cycle through (with a quick way to
get out of it).

While interesting, I'm not sure why I wouldn't bypass screen and just
feed the output of command XYZ through gnuplot itself instead of
scraping off of screen; I'm having a hard time thinking of an example
where I can't just get at the text directly and would have to go through
screen to get at data.

My friends and I are very interested in exploring
multiuser-capabilities; the ACLs seem to be the barrier to entry for us.


Thanks a lot for the work!
