Getting System Help and Information

In addition to the hardcopy documentation described in the preface of this document (About This Document), the HP XC system also provides system help and information in the form on online manpages.

Manpages provide online reference and command information from the system command line. Manpages are supplied with the HP XC system for standard HP XC components, Linux user commands, LSF commands, SLURM commands, and other software components that are distributed with the HP XC system, such as HP-MPI. Manpages for third-party vendor software components may be provided as a part of the deliverables for that software component.

To access manpages, type the man command with the name of a command. For example:

$ man sinfo

This command accesses the manpage for the SLURM sinfo command.

If you are unsure of the name of the command that you need to reference, you can enter the man command with the -koption and a keyword, to get a list of commands that are related to the keyword you entered. For example:

$ man -k keyword

The MANPATH environment variable is a list of directories that the man command uses to find a manpage. You may need to add to your MANPATH variable to identify the location of manpages for additional software packages.
