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 ensure 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:

See the HP XC System Software User's Guide for more information about modulefiles.

	Notes: Installing a package in a nondefault location means that you must update the corresponding modulefile; you might need to edit the PATH and MANPATH environment variables. Other changes are based on the software package and its dependencies. If you have installed a variant of the package, you might need to create a parallel modulefile specifically for the variant. For example, you might have a standard application that you need to keep separate from a beta version of the same application; in this case, you would set up a parallel modulefile and adjust it accordingly.
