Typographical Conventions

Italic font

Courier font

Italic (slanted) font indicates the name of a variable that you can replace in a command example or information in a display that represents several possible values.

Document titles are shown in Italic font. For example: Linux Administration Handbook.

Courier font represents text that is displayed by the computer. Courier font also represents literal items, such as command names, file names, routines, directory names, path names, signals, messages, and programming language structures.

Bold text

In command and interactive examples, bold text represents the

 

literal text that you enter. For example:

 

# cd /opt/hptc/config/sbin

 

In text paragraphs, bold text indicates a new term or a term that is

 

defined in the glossary.

$ and #

In command examples, a dollar sign ($) represents the system

 

prompt for the bash shell and also shows that a user is in non-root

 

mode. A pound sign (#) indicates that the user is in root or superuser

 

mode.

[ ]

In command syntax and examples, brackets ([ ]) indicate that

 

the contents are optional. If the contents are separated by a pipe

 

character ( ), you must choose one of the items.

{}

...

In command syntax and examples, braces ({ }) indicate that the contents are required. If the contents are separated by a pipe character (), you must choose one of the items.

In command syntax and examples, horizontal ellipsis points ( … ) indicate that the preceding element can be repeated as many times as necessary.

...

In programming examples, screen displays, and command output, vertical ellipsis points indicate an omission of information that does not alter the meaning or affect the user if it is not shown.

In command syntax and examples, a pipe character ( ) separates items in a list of choices.
