Other Sources of Information
Your system administrator or nearby UNIX users probably have copies of UNIX manuals lying around. The pages of some of these manuals usually look much like the manual pages you get with man .The advantage of the printed manual is that an index is in the front (or the back). It is usually a permuted or KWIC index (an overly clever abbreviation for key word in context), which means that you can find an entry by looking under any of the words in the title except for boring ones, such as the. To find the page for the cp command (the title of the manual page is cp, ln, mv — copy, link, or move files), for example, you can look in the permuted index under cp, ln, mv, copy, link, move, or files.Then again, typing help is not a bad idea, just to see what happens. Someone may have installed some kind of help system — you never know.UNIX is used widely enough that a growing industry of UNIX books, magazines, user groups, and conferences has sprung up. Any of them can provide additional help and information.
Read a magazine
Several weekly or monthly magazines cover UNIX. Most of them include in their titles either the name UNIX or the code phrase Open Systems (for systems that act like UNIX but haven’t licensed the UNIX trademark). Because you probably have already thrown away mail inviting you to subscribe to most of them, we don’t belabor the point. The major brands of workstations (Sun, Hewlett-Packard, and IBM) also have magazines that specifically cover those product lines. Although some of these magazines tend to be awfully technical, they can be interesting for product reviews and announcements about new UNIX hardware and software packages.Linux If you use Linux, take a look at the Linux Journal, the magazine for and about Linux. (Subscription info is at www.linuxjournal.com .) The technical level varies from totally introductory to fairly technical. Also see its online Linux Gazette at www.linuxgazette.com/ .
Read a book
Yeah, we know: You may have (or not) just read this book. We mean read another book. Here are a few you may like:
Levine and Young, UNIX For Dummies Quick Reference, 4th Edition; Wiley Publishing, Inc. (Big surprise.) The Quick Reference has essential information from the book you’re reading and a detailed command reference, squashed down into a smaller, less expensive, pocket-size form.
UNIX in a Nutshell; O’Reilly. A complete UNIX reference, the one we turn to when memory fails. It comes in various editions for different versions of UNIX and is intended for more advanced users than our UNIX For Dummies Quick Reference.
Linux LeBlanc, Linux For Dummies, 5th Edition; Wiley Publishing, Inc. This one tells how to survive installing, using, administering, and networking Linux, for beginners with some technical tolerance.
Welsh and Kaufman, Running LINUX, 4th Edition; O’Reilly. All about installing and using Linux, it’s medium technical but quite informative.
Naba Barkakati, Red Hat Linux Secrets; Wiley Publishing, Inc. This one covers a wide range of topics, from hardware debugging to using Linux in your business.
Join a user group
The major UNIX user group is called Usenix, and dates back to about 1976; it is traditionally for technical users. It sponsors annual conferences and publishes a newsletter. Visit www.usenix.org/ to see what it’s up to. You can also find local and regional UNIX user groups; you tend to find out about these groups from notes posted on physical or electronic bulletin boards. User groups can be great sources of help because chances are good that someone already has run into many of the same problems you have and has some ideas that may help.
