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
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.
This style indicates that the program is an end-user application
(as opposed to system software). For example:
Use Mozilla to browse the Web.
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
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).
Select the Require Password checkbox if
you would like your screensaver to require a password before
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 on a GNOME terminal, the
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 (the main menu on the
panel) => => to start the Emacs text editor.
- button on a GUI screen or window
This style indicates that the text can be found on a clickable
button on a GUI screen. For example:
Click on the Back button to return to
the webpage you last viewed.
- computer output
Text in this style indicates text displayed to a shell prompt
such as error messages and responses to commands. For example:
The ls command displays the contents of
a directory. For example:
Desktop about.html logs paulwesterberg.png
Mail backupfiles mail reports
The output returned in response to the command (in this case,
the contents of the directory) is shown in this style.
A prompt, which is a computer's way of signifying that it is
ready for you to input something, is shown in this style.
[[email protected] stephen]$
- user input
Text that the user has to type, either on the command line, or
into a text box on a GUI screen, is displayed in this style. In the
following example, text is displayed
in this style:
To boot your system into the text based installation program,
you must type in the text command at
the boot: prompt.
Text used for examples, which is meant to be replaced with data
provided by the user, is displayed in this style. In the following
example, <version-number> is
displayed in this style:
The directory for the kernel source is /usr/src/kernels/<version-number>/, where <version-number> is the version and type
of kernel installed on this system.
