This guide uses the following syntax conventions for the utility commands and parameters:
All UPPERCASE letters are used for most command names and for most parameter names, regardless of the type of platform. However, positional parameters for which you enter a specific value are shown in lowercase and italics, for example,
instance
.
Square brackets [ ] indicate optional parameters. You can consider any parameters without these brackets to be required.
A vertical bar | separates alternative options of which one can be entered for a parameter.
Single braces { } enclose alternative entries. Use only one of the entries. Do not type the braces when you enter the option.
Underlining indicates the default option for a parameter, if available.
Italics indicate a variable or positional parameter for which the value varies.
