[ILUG] Script Query

[Ian]

Cheers Colm,
Killall should do the trick. nice to have the other option also.
As for the terminal opening when launching firefox.

I'm actually running the sh script within the shell itself, perhaps this is
why the shell also remains running after firefox opens. Is there a way I can
supress this?
I don't expect to be running the script this way when i have everything
written so it may not be a problem down the road.
