Very Computer

I am trying to write a shell script to only allow a single instance of
PINE to run under X (with windowmaker 0.64).

What I am trying to do is force a existing instance of PINE to the
forground from a script in a different shell session. And this is the
problem, how do I force this process to the forground? I can get the
process ID with no problems.

BTW. I am using bash.

Any suggestions?

Thanks.

What you probably want to do, is replace the command with which you
start pine with a script that checks if you're running X (this can be
done by either checking the DISPLAY environment variable or seeing if
TERM is something like 'xterm'* or 'rxvt'. The last option is probably
the neatest, considering what I'm going to suggest). Then if you are
in fact running under X, you use the xsetfocus[1] utility to set the
focus to a window named 'pine'. If this fails (see the exit status of
xsetfocus), set the X-term title to 'pine' (check the Bash-prompt howto
for how to do this). If xsetfocus doesn't fail, the focus is now on
the pine, and you can exit the shell script.

[1] Xsetfocus is a small util I've written (http://www.var.cx/utils/xsetfocus.c)
(I still can't believe there's nothing like this that comes with XFree,
I've probably just missed it. But for the time being, this works).
