For Linux, I think we should just use something like pid.sessionname
.
For other Unix-like OS, it may also indicate the TTY like this pid.tty.sessionname
.
To be sure, consult your manpage of screen : man screen

I have recently come across this post which says that it is possible to force a script to run in screen with a shebang. My question is, how does one do this if I want to reconnect to an existing screen session (and thus force the script to run under screen).
So, on my server, when I do screen -list
, I see:
There is a screen on:
22566.myscreen (10/26/13 23:47:09) (Detached)
1 Socket in /var/run/screen/S-admin.
Now, I have the following bash script, and I would like the bash script to be run with the above screen session. At the moment, I have something like this:
#!/usr/bin/screen -r "myscreen" /bin/bash
# /home/foo/jobscripts/script.sh
#
echo $STY
git status
touch /home/foo/jobscripts/testsuccess.txt
exit 0
... but this obviously does not work and tells me Error: Unknown option r "myscreen" /bin/bash
Wondering if there was a way to specify in shebang to reattach to my above screen.
