Section 0.2:Document Conventions
A prompt, which is a computer's way of signifying that it is ready for you to input something,
will be shown in this style. Examples:
$
#
[stephen@maturin stephen]$
leopard login:
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 will need to type in the text
command at the boot: prompt.
Another example, with the word root displayed as something the user needs to type in:
If you need to log in as root when you first log into your system, and you are using the graphical
login screen, at the Login prompt, type root. At the Password prompt, type in the root
password.
glossary entry
A word that appears in the glossary will be shown in the body of the document in this style. For
example:
The lpd daemon handles printing requests.
In this case, the style of the word daemon should indicate to you that a definition of the term is
available in the glossary.
Additionally, we use several different strategies to draw your attention to certain pieces of information.
In order of how critical the information is to your system, these items will be marked as a note, a
caution or a warning. For example:
Remember that Linux is case sensitive. In other words, a rose is not a ROSE
is not a rOsE.
