Red Hat Linux uses the man command to display online help text. The text to be displayed is known as man page, and is displayed using the command:

man<man-page>

(Replace <man-page> with the name of the desired man page.)

Often you will see a man page followed by a number or letter within parentheses; this number or letter denotes the section under which the man page is filled. The sections include;

• Section 1 – user commands
• Section 2 – system calls
• Section 3 – subroutines
• Section 4 – devices
• Section 5 – file formats
• Section 6 – games
• Section 7 – miscellaneous
• Section 8 – system administration
• Section I – local
• Section n – new

For example is chroot (1) and chroot (2) where the is one instance of the section number exists with the same name, you need to include the section number such as below command:

man 2 chroot

To display the next man page, press the [Space] bar key; and to quit, press [Q].
