activities:
•
Linux system administration procedures, including kernel configuration
•
Installation and configuration of shared storage networks, such as Fibre Channel SANs
2. Document Conventions
When you read this manual, certain words are represented in different fonts, typefaces, sizes, and
weights. This highlighting is systematic; different words are represented in the same style to indicate
their inclusion in a specific category. The types of words that are represented this way include the
following:
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.
