command

Linux commands (and other operating system commands, when used) are represented this way.

This style should indicate to you that you can type the word or phrase on the command line

and press [Enter] to invoke a command. Sometimes a command contains words that would be

displayed in a different style on their own (such as file names). In these cases, they are considered

to be part of the command, so the entire phrase is displayed as a command. For example:

Use the

cat testfile

command to view the contents of a file, named

testfile

, in the current

working directory.

file name

File names, directory names, paths, and RPM package names are represented this way. This style

should indicate that a particular file or directory exists by that name on your system. Examples:

The

.bashrc

file in your home directory contains bash shell definitions and aliases for your own

use.

The

/etc/fstab

file contains information about different system devices and file systems.

Install the

webalizer

RPM if you want to use a Web server log file analysis program.

application

This style indicates that the program is an end user application (as opposed to system software).

For example:

Use Mozilla to browse the Web.

[key]

A key on the keyboard is shown in this style. For example:

To use [Tab] completion, type in a character and then press the [Tab] key. Your terminal displays

the list of files in the directory that start with that letter.

[key] [combination]

A combination of keystrokes is represented in this way. For example:

The [Ctrl] [Alt] [Backspace] key combination exits your graphical session and returns you to the

graphical login screen or the console.

text found on a GUI interface

A title, word, or phrase found on a GUI interface screen or window is shown in this style. Text

shown in this style is being used to identify a particular GUI screen or an element on a GUI

screen (such as text associated with a checkbox or field). Example:

Select the Require Password checkbox if you would like your screensaver to require a password

before stopping.

top level of a menu on a GUI screen or window

A word in this style indicates that the word is the top level of a pulldown menu. If you click on

the word on the GUI screen, the rest of the menu should appear. For example:

Under File on a GNOME terminal, the New Tab option allows you to open multiple shell

prompts in the same window.

If you need to type in a sequence of commands from a GUI menu, they are shown like the

following example:

Go to Applications (the main menu on the panel) => Programming => Emacs Text Editor to

start the Emacs text editor.
