Basic commands

Basic commands to access software provided via EESSI

EESSI provides software through environment module files and Lmod.

To see which modules (and extensions) are available, run:

module avail

Below is a short excerpt of the output produced by module avail, showing 10 modules only.

   Qt5/5.15.2-GCCcore-10.3.0                               (D)
   R/4.1.0-foss-2021a                                      (D)
   re2c/2.1.1-GCCcore-10.3.0                               (D)

Load modules with module load package/version, e.g., module load R/4.1.0-foss-2021a, and try out the software. See below for a short session
