Groups

Each system user also belongs to one or multiple groups. Users generally belong to a default group for all users. Groups are also a way to customize permissions for various sets of users. Instead of continuously setting up permissions for single users, these individuals can be placed instead in an assembly.

As an example if a user creates a file, although the individual user owns the file it will routinely be possessed by the user’s default group as well. More modern Linux systems are allowing for the creation of groups which utilize the equivalent designation as the user. This is known as “User Private Group Scheme”. This is said to be a far more protected decision.

Much like that of the user ids, groups also have numerical based ids. This can also be signified as the groupid (or gid). Users are able to be added to groups by simply using the following command: sudo usermod -a -G lpadmin user1.
