groupdel(1M)						  System Administration Commands					      groupdel(1M)

NAME

       groupdel - delete a group definition from the system

SYNOPSIS

       /usr/sbin/groupdel group

DESCRIPTION

       The groupdel utility deletes a group definition from the system. It deletes the appropriate entry from the /etc/group file.

OPERANDS

       group	An existing group name to be deleted.

EXIT STATUS

       The following exit values are returned:

       0     Success.

       2     Invalid command syntax. A usage message for the groupdel command is displayed.

       6     group does not exist.

       10    Cannot update the /etc/group file.

FILES

       /etc/group    system file containing group definitions

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWcsu			   |

SEE ALSO

       users(1B), groupadd(1M), groupmod(1M), logins(1M), useradd(1M), userdel(1M), usermod(1M), attributes(5)

NOTES

       The  groupdel utility only deletes a group definition that is in the local /etc/group file. If a network nameservice such as NIS or NIS+ is
       being used to supplement the local /etc/group file with additional entries, groupdel cannot change  information	supplied  by  the  network
       nameservice.

       groupdel fails if a group entry (a single line in /etc/group) exceeds 2047 characters.
