SGI systems shipped with Linux include a set of Linux man pages, formatted in the standard
UNIX “man page” style. Important system configuration files and commands are documented on
man pages. These are found online on the internal system disk (or DVD) and are displayed using
the man command. References in the documentation to these pages include the name of the
command and the section number in which the command is found. For example, to display a man
page, type the request on a command line:
man commandx
For additional information about displaying man pages using the man command, see man(1). In
addition, the apropos command locates man pages based on keywords. For example, to display
a list of man pages that describe disks, type the following on a command line:
apropos disk
