May I point out that environment variables used in [Li,U]n*x can do
pretty much the same thing? i.e $HOME stores your home directory path.

So, how do I change the $HOME of my *parent* process? <evil grin...>


That's what source is for (in bash) and it's what I use in this case. :-)

Yes, I know it's not the same as altering the parent process environment
table, but it has the same effect as if it did when you want to customise
your environment in a controlled way for some reason.
