# Administration Reference

## Typographical Conventions

This document uses the following typographical conventions:

- Command and option names appear in bold type in syntax definitions, examples, and running text. Names of directories, files, machines, partitions, volumes, and users also appear in bold type.

- Variable information appears in italic type. This includes user-supplied information on command lines and the parts of prompts that differ depending on who issues the command. New terms also appear in italic type.

- Examples of screen output and file contents appear in `monospace type`.

In addition, the following symbols appear in command syntax definitions, both in the documentation and in AFS online help statements. When issuing a command, do not type these symbols.

- Square brackets [ ] surround optional items.

- Angle brackets < > surround user-supplied values in AFS commands.

- A superscripted plus sign + follows an argument that accepts more than one value.

- The percent sign `%` represents the regular command shell prompt. Some operating systems possibly use a different character for this prompt.

- The number sign `#` represents the command shell prompt for the local superuser root. Some operating systems possibly use a different character for this prompt.

- The pipe symbol | in a command syntax statement separates mutually exclusive values for an argument.
