Thanks to everyone who provided the many different solutions to the
shell game.  I've used several of them in my work and I've learned a bit
as well.

Now I'd like to know what to do about the following:

I'm working on a system whereby I receive emails via exim/fetchmail
(done), invoke a shell script via .forward (done), decode any jpg
attachements and save into a directory (done), and hand off those
pictures to the gimp (the shell game - done).  The problem is that gimp
can't open an X display and dies.  Obviously, if I invoke the script
from my xterm, it's fine.  I've tried 'xhost +localhost' and have spent
most of the day googling to find the answer.  I'm so close to victory I
can taste it. Anybody?

Thanks again,

-- Drew.
