System User's Guide: Operating System and Devices

About This Book

This book contains information for novice system users who want to acquire greater expertise with the operating system. It covers information such as running commands, handling processes, handling files and directories, and printing. In addition, it introduces tasks such as securing files, using storage media, customizing environment files (.profile, .Xdefaults, .mwmrc), and writing shell scripts. For DOS users, this guide presents procedures on using DOS files in this environment.

Users in a networked environment who are interested in learning more about operating system communications commands should read the AIX 5L Version 5.2 System User's Guide: Communications and Networks.

Who Should Use This Book

This book is intended for all system users.


The following highlighting conventions are used in this book:

Bold Identifies commands, keywords, files, directories, and other items whose names are predefined by the system.
Italics Identifies parameters whose actual names or values are to be supplied by the user.
Monospace Identifies examples of specific data values, examples of text similar to what you might see displayed, examples of portions of program code similar to what you might write as a programmer, messages from the system, or information you should actually type.

Case-Sensitivity in AIX

Everything in the AIX operating system is case-sensitive, which means that it distinguishes between uppercase and lowercase letters. For example, you can use the ls command to list files. If you type LS, the system responds that the command is "not found." Likewise, FILEA, FiLea, and filea are three distinct file names, even if they reside in the same directory. To avoid causing undesirable actions to be performed, always ensure that you use the correct case.
