Modules Environment

Modules Environment

The Environment Modules system is a tool to help users manage their Unix or Linux shell environment, by allowing groups of related environment-variable settings to be made or removed dynamically. It has been around since the early nineties, but seems to be used mainly at large computer centers, where it's used to deploy multiple versions of different software tools to users.

The modules system is based on modulefiles, which specify groups of environment settings that need to be made together. Modulefiles can be installed in a central location for general use, or in a user directory for personal use. The module command can then be used to "load" or "unload" these modules in your environment, to list the available or loaded modules, show what settings they make, etc.
