Modulefiles
Modulefiles provide a mechanism for accessing software commands and tools, particularly for third-party
software. The HP XC System Software does not use modules for system-level manipulation.
A modulefile contains the information that alters or sets shell environment variables, such as PATH and
MANPATH. Some modulefiles are provided with the HP XC System Software and are available for you to
load. A modulefile must be loaded before it changes the user's environment.
See the HP XC System Software User's Guide for information on creating modulefiles and loading default
modulefiles.
The module command is a shell function that should be defined when users log into the system. It is not found
in the path; you can check this function exists by running the following command under the Bourne, Korn,
or bash shells:
$ typeset -f module
The module command features keywords that enable you to load, unload, and list modules, as described
here:
• Use the load keyword to load a module:
# module load package-name
• Use the list keyword to list all loaded modules:
# module list
Be sure to unload a module before loading another to help avoid module versioning conflicts. See the
HP XC System Software User's Guide for additional information.
• Use the avail keyword to list all loaded or unloaded modules:
