## What This Handbook Covers

Learning the UNIX Operating System teaches the basic system utility commands to get you started with UNIX. Instead of overwhelming you with a lot of details, we want you to be comfortable in the UNIX environment as soon as possible. So we cover the most useful features of a command instead of describing all its options in detail. Appendix A, Reading List , lists other references.

After reading this handbook, you should be able to:

- Log in and log out of your system

- Control the system with control characters

- Send messages to other users

- Manage UNIX files and directories, including listing, creating, copying, printing, and removing files, and moving in and out of directories

- Work more efficiently using UNIX pipes, filters, and multitasking
