This section describes common typographical use conventions.

Convention Description/Example


A call-out is a number in the body text to give you a visual reference. The reference point is for further discussion elsewhere.

You can use this resource regularly.

Code in text

Inline code samples (including XML) and commands are identified with a special font.

You can use the command java -version.

Code blocks

Blocks of sample code are set apart from the body and marked accordingly.

# ls -l /var/www/html/index.html -rw-rw-r-- 1 root root 1872 Jun 21 09:33 /var/www/html/index.html # date Wed Jun 21 09:33:42 EDT 2006

Symbol Conventions

This section describes the common use of symbols.

Convention Symbol Description/Example

Mutually exclusive parameters

Optional parameters

XML variable text

[square brackets]

Within a code description, square brackets denote completely optional commands or parameters.

% sed [-n, -quiet]

Use square brackets in XML examples to differentiate them from tags.



<arrow brackets>
