Yah. Your "sourcing" explanation was much better. I figured I hadn't
explained it well. All it does is simply run the script in the current
shell instead of forking a child shell; one of the main side-effects is
that any environment changes from the script happen in the current shell.
This does not work in, for instance, the C shell. It *does* work in the
Korn shell, though. So, you must be careful not to "source" a Korn
shell script in Bash shell.
Well, considering nobody uses the Korn shell anymore, I guess you don't
have to be *that* careful.
