Manpages

Manpages provide online reference and command information from the command line. Manpages are supplied with the HP XC system for standard HP XC components, Linux user commands, LSF commands, and other software components that are distributed with the HP XC system.

Manpages for third-party vendor software components may be provided as a part of the deliverables for that component.

Using the discover(8) manpage as an example, you can use either of the following commands to display a manpage:

$ man discover $ man 8 discover

If you are not sure about a command you need to use, enter the man command with the -koption to obtain a list of commands that are related to the keyword. For example:

$ man -k keyword
