Just a quick FYI for the beginners out there who are looking for information on something:

1. See if there is a man page related to your topic: try "man -k topic | less" and then read the related man page. Man pages can be a bit tricky to get the hang of at first; they tend to be very terse, but a lot of information is packed into them.
2. There is a lot of documentation under /usr/doc that can be a little hard to find. First, it's generally located under /usr/doc/packagename, where packagename is the name of the package. On rpm-based systems, you can use "rpm -qf" to find out what package a file is in. Suppose that you're interested in lilo. First "which lilo" will say "/sbin/lilo". Next, "rpm -qf /sbin/lilo" will say "lilo-0.21-6". Now, "cd /usr/doc/lilo0.21" and "ls"--there's a whole wealth of information about lilo ther.
3. The Linux documentation project at has a lot of good stuff, including the most up-to-date HOWTOs, mini-HOWTOs, man pages, and Linux FAQs.
4. The Usenet FAQs at are often useful, especially the comp.unix FAQ in the unix directory there.
5. The GNU info pages are sometimes useful; "info" will get you started.
6. If all else fails, post questions here or to the comp.os.linux.* Usenet newsgroups!

For programmers, the comp.lang.c, comp.lang.c++, and comp.unix.programmer are mandatory reading. Also, the Single Unix Specification at requires a free registration but is helpful when trying to write portable code.
