Red Hat ENTERPRISE LINUX 3 System Administration Manual page 11

Introduction
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
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 file in your home directory contains bash shell definitions and aliases for your own
.bashrc
use.
The
/etc/fstab
Install the
webalizer
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 return 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 Main Menu Button (on the Panel) => Programming => Emacs to start the Emacs text
editor.
command to view the contents of a file, named
file contains information about different system devices and file systems.
RPM if you want to use a Web server log file analysis program.
