1.001: I know neither Unix nor AIX - where do I find more information?

If you are new to Unix, you should look at the other newsgroups in the
comp.unix hierarchy, in particular comp.unix.questions.  There are
FAQs more most of these groups as well.

If you need information about C programming, try comp.lang.c or
comp.std.c, the latter for Standard ANSI C issues.  comp.lang.c has a
FAQ posting.
