DESCRIPTION
The `groupmems` command allows users to manage their own group memberships, or allows administrators to manage group memberships for any user. It can list, add, and delete group memberships. It is particularly useful in environments where users are allowed to administer their own group memberships. The command is an interface for modifying the /etc/group file or another appropriate backend like LDAP. Without any options, `groupmems` displays the groups a user belongs to. When invoked by the root user, it can be used to manage memberships for any user account. Using `groupmems` requires the caller to have the necessary permissions to modify group memberships. It can be used to either list the users that are part of a group or it can be used to modify the group memberships. The command's behavior depends on the user running the command and what flags are used. It is a simple command but provides great utility to both end users and administrators for effective group management.
PERMISSIONS
Regular users can only modify their own group memberships. Modifying other users' group memberships requires root privileges.
SECURITY CONSIDERATIONS
Care should be taken when granting users the ability to manage their own group memberships, as it can potentially be used to escalate privileges. Administrators should carefully consider the implications before allowing such access.
