Data Msg before exiting pseudo-console
Hi! I want to display a message when I leave a pseudo-console (/dev/ptsX: konsole, xterm) e.g "Bye! There's still 3 pts open and 3 background processes"
I can do it in login-terminals (via .bash_logout) but not in a non-login...
Any ideas?

Why would you want to message a non-login terminal? Your messages could end up in places they're unneeded and unwanted.

My work is mostly with non-login terminals. I just want to get some information when I leave an xterm.. that's all. It's my personal use unix system I'm not dealing with clients, other users, etc.

It's the shell which is told to do things on logout, not anything fundamental to the terminal. If you're not running shells in these terminals, what are they doing?

Thanks for your response! Yes, you're right I'm running shells in these psudo-terminals. Is there a way the shell to know if it's running on a system console /dev/ttyX or a psudo-terminal (/dev/ptsX)?

A close look at the contents of /proc/self/fd could help.

Code:
$ ls -l /proc/self/fd/
total 0
lrwx------ 1 monttyle monttyle 64 Oct 16 20:59 0 -> /dev/pts/0
lrwx------ 1 monttyle monttyle 64 Oct 16 20:59 1 -> /dev/pts/0
lrwx------ 1 monttyle monttyle 64 Oct 16 20:59 2 -> /dev/pts/0
lr-x------ 1 monttyle monttyle 64 Oct 16 20:59 3 -> /proc/18647/fd

...but when I do so from a physical console I get things like /dev/tty1.
