RELATED: How to See Which Groups Your Windows User Account Belongs To

Groups help define the permissions and access your Linux user account has to files, folders, settings, and more. Finding out the groups to which a user account belongs helps give you a better understanding of that user’s access (and troubleshoot when things don’t work right).

You can also add a username after the groups command if you’re investigating group membership for a different account. Just use the syntax:

groups <username>
