An application is the name of a GUI software program. A command is the name of an executable (text) program or a software command. Any program that is a command line or text-based only tool is marked with command tags.

If you have text that is a command, use the <command> and </command> tags such as:

To change your keyboard after installation, become root 
and use the <command>redhat-config-keyboard</command> command, 
or you can type <command>setup</command> at the root prompt.

The output:

To change your keyboard after installation, become root and use the redhat-config-keyboard command, or you can type setup at the root prompt.

Another example would be:

<command>MAILNOVIOLATIONS</command> — If set
to <command>true</command> this option tells Tripwire to
email a report at a regular interval regardless of whether or not
any violations have occured. The default value is
<command>true</command>.

with the output:

MAILNOVIOLATIONS — If set to true this variable tells Tripwire to email a report at a regular interval regardless of whether or not any violations have occured. The default value is true.

	Note
	In this example, the option value (true) is defined with a <command> tag set. Because a option is a configuration file option (command line options which would use the <option> tag set), and because there is no configuration file option tag available to use, we are extending the <command> tag set to define options in a configuration file.

Terms marked with command tags because there aren't exact tags for them:
