Groups

Groups in Unix systems are used for multiple purposes, including controlling access to files and directories, and limiting executing of some binaries. A user could be assigned to multiple groups.

In HPC clusters, groups are also used to grant accesses to a specific partition on Slurm, which is the job management software.
