I'm a happy camper. Thanks for your help.
Glad it's working for you again.
PS. Is there some good reference to explain shell variables and
environment variables, how they're set and their lifetime.
Well, there are the manual pages for the shells (tcsh/csh (same thing
on freebsd), sh, bash (see ports)), but really they can be quite cryptic
and difficult to figure out if you don't know the basic answers already.
I'd personally say that if this is the kind of question you are asking
that a good book is the answer. I can't recommend anything specific
since I don't have a single UNIX reference book. However, the author of
one FreeBSD book regularly posts to this mailing list so just look
through the archives for that (called Complete FreeBSD or some such) and
there are bound to be O'Reilly books that you'd find useful, maybe Unix
Power Tools. That certainly has csh stuff and I'm sure I found some csh
stuff from it on-line one time, though, typically, I can't find it now.
Failing that, you could try google and see if you come across any good
how-to's, guides etc.
Other's may have other suggestions.
