2. Document Conventions
In 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 indicates that a particular file or directory exists with that name on
your system. Examples:
