Commands and keywords are in boldface font.

Arguments for which you supply values are in italic font.

Elements in square brackets ([ ]) are optional.

Alternative but required keywords are grouped in braces ({ }) and separated by vertical bars (). Examples use these conventions:

Terminal sessions and sample console screen displays are in screen font.

Information you enter is in boldface screen font.

Nonprinting characters, such as passwords, are in angle brackets (< >).

Default responses to system prompts are in square brackets ([ ]).

Exclamation points (!) at the beginning of a line indicate a comment line.

Caution Means reader be careful. You are capable of doing something that might result in equipment damage or loss of data.

Note Means reader take note. Notes contain helpful suggestions or references to materials not contained in this manual.
