Add an user group
lgroupadd [OPTION]... group
Adds a new user group with name group.
-g, --gid=gid
Use group ID gid for the newly created group. A group ID is selected automatically if this option is not present.
-i, --interactive
Ask all questions when connecting to the user database, even if default answers are set up in libuser configuration.
-r, --reserved
The group is a system group. Groups that are not marked as system groups usually have automatically selected group IDs above a certain value (configured as LU_GIDNUMBER in libuser.conf(5)). This information is also passed to the libuser backends.
The exit status is 0 on success, nonzero on error.
