10. Online Unix References and Tutorials

As Linux is a Unix-like operating system, a general familiarity with fundamental Unix concepts such as the Unix directory hierarchy and file permissions is essential. Fortunately, there are many Unix tutorials online that collectively cover everything a user might need to know to use Linux. I suggest you bookmark the following as an online reference library:

• The Command and Shell User's guide from Digital Equipment Corporation is an excellent guide to the Unix Operating System. Bookmark the Index Page linked there as an online reference.

• UNIXhelp is mirrored on many servers around the world. It is a useful resource for newbies.

• Introduction to Unix also contains a useful Unix Command Summary page with brief, but useful, explanations of commonly used Unix commands.

• Unix is a Four Letter Word... is another resource suitable for newbies.
