Lmod

In linux environment variables are values that can change and impact how programs behave on a computer system. They are name-value pairs that all processes can access within a particular user environment or shell session. These variables provide a flexible and convenient method for managing system-wide settings, configuring applications, and customizing system behavior.

Shabyt uses Environment modules (also know as LMOD) to dynamically set up environment variables for different software. Module commands set, change, or delete environment variables that are needed for a particular software. The ‘module load‘ command will set PATH, LD_LIBRARY_PATH and other environment variables such that user may choose a desired version of applications or libraries more easily.
