The
groupadd utility adds a group to the system. See
group(8) for more information about
EXTENSIONS. The options are as follows:
-g gid
Give the numeric group identifier to be used for the new group.
-o
Allow the new group to have a gid which is already in use for another group.
-r lowgid..highgid
Set the low and high bounds of a gid range for new groups. A new group can only be created if there are gids which can be assigned inside the range. This option is included if built with EXTENSIONS.
-v
Enable verbose mode - explain the commands as they are executed. This option is included if built with EXTENSIONS.
