About This Book

This book provides experienced programmers with complete, detailed information about files for the AIX® operating system. Files are listed alphabetically, and complete descriptions are given for each file. It includes information on file formats, special files, system files, header files, directories, and related information associated with files. This publication is also available on the documentation CD that is shipped with the operating system.

How to Use This Book

This book contains sections on the system files, special files, header files, and directories that are provided with the operating system and optional program products. File formats required for certain files that are generated by the system or an optional program are also presented in a section of this book.

Highlighting

The following highlighting conventions are used in this book:

Bold	Identifies commands, subroutines, keywords, files, structures, directories, and other items whose names are predefined by the system. Also identifies graphical objects such as buttons, labels, and icons that the user selects.
`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.
