# 9. 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 Wikipedia Unix article is a good place to start. It includes an Unix history, explains some Unix concepts and includes an explanation of basic commands and some relevant links.

- Eric S. Raymond's The Unix and Internet Fundamentals HOWTO is a good document to learn about the Unix concepts.

- The UNIX Tutorial for Beginners of the University of Surrey is a good step by step tutorial for beginners.

- 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.
