Module Software Management
The Module tool is used for managing software environments, enabling users to flexibly switch between different software packages and their versions. It simplifies environment configuration and avoids dependency conflicts between software.
Environment Modules (Module): They represent specific software packages and versions. Once loaded, they modify environment variables (such as PATH, LD_LIBRARY_PATH, etc.) to make the software available.
Module Files (Modulefile): These are the files that define environment modules, specifying information such as software dependencies and paths.
Add necessary module loading commands at the beginning of the script to ensure consistency of the running environment.
Common Commands

module avail: Lists all available modules, showing the software names and versions.
