       groupmod - modify a group definition on the system

SYNOPSIS
       groupmod [-g gid [-o]] [-n name] group

   where:

              <sys/param.h>

DESCRIPTION
       The groupmod command modifies the definition of the specified group
       by modifying the appropriate entry in the /etc/group file.

       The following options are available:

       -g gid Set the group id for the new group.  The group ID defaults to
              the next available (unique) number above 99.  (Group IDs from
              0-99 are reserved.)

       -o     Allow the gid to be duplicated (non-unique).

       -n name
              Specify a new name for the group.
