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. --Alex
