Highlighting

The following highlighting conventions are used in this guide:

Bold

Identifies commands, subroutines, keywords, files, structures, 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.
