4.2 Man Pages
Man pages are an essential part of any Linux system. They explain the usage of a
command and all available options and parameters. Man pages are sorted in categories
as shown in Table 4.1, “Man Pages—Categories and Descriptions” (page 127) (taken
from the man page for man itself).

Executable programs or shell commands

Generally, man pages are delivered with the associated command. They can be browsed
in the help center or directly in a shell. To display a man page in a shell, use the man
command. For example, to display the man page for ls enter man ls. Each man page
consists of several parts labeled NAME, SYNOPSIS, DESCRIPTION, SEE ALSO, LI-
CENSING, and AUTHOR. There may be additional sections available depending on
the type of command. With Q , exit the man page viewer.
