See the bibliography in Appendix D for a list of different books available on Unix. The best way to learn Unix is to use it. Sit down at a terminal with this manual and try the different commands and examples. However, be sure when experimenting not to do so on important files, as you may inadvertently delete or change something while you are learning the system. Should you find any errors or omissions in this manual, please contact the System Administrator so that future editions can be corrected.
Feedback is always welcome.
This manual uses several typographic conventions to indicate different things. Places where you must substitute some specific name, command, or option are in Helvetica bold italic. Assume that it must be pressed after every command. Some keys on the computer keyboard cannot be designated by single characters in examples. Certain keys on the computer keyboard don't perform actions except when other keys are pressed at the same time.
