-g gid
Specify group id
-r
Create a system group
-f
Add an existing group account and the system will get an error message and end the groupadd. If this is the case, the group will not be added (if this is the case, the system will not add it again), but also the-g option can be added at the same time. When you add a gid, the gid does not have to be the only value, but without the-o parameter, the result will be displayed after the group is built.

/ etc/group, group information.
/ etc/gshadow, group encrypted messages.
