rmgroup [ -R load_module ] Name
The rmgroup command removes a group specified by the Name parameter. This command deletes all the group attributes as well. To remove a group, the group name must already exist as a string of 8 bytes or less. Users who are group members are not removed from the system.
If the group is the primary group for any user, you cannot remove it unless you redefine the user's primary group with the chuser command. The chuser command alters the /etc/passwd file. Only the root user or a user with GroupAdmin authorization can remove an administrative group or a group with administrative users as members.
For groups that were created with an alternate Identification and Authentication (I&A) mechanism, the -R flag can be used to specify the I&A load module used. Load modules are defined in the /usr/lib/security/methods.cfg file.
You can use the Users application in Web-based System Manager (wsm) to change user characteristics.
You could also use the System Management Interface Tool (SMIT) smit rmgroup fast path to run this command.
