       groupadd - add a new group to the system

       gid group

       The command creates a new group on the system by adding the appropriate
       entry to the file.  The command must be used with the  group  argument,
       which  is  the name of the new group.  The name consists of a string of
       printable characters that may not include a colon or newline

       Refer to usergroupname(5) to understand the functionality changes  with
       the Numeric User Group Name feature.

       The command uses the following options:

	      Specify the group ID
			for the new group.  gid must be a non-negative decimal
			integer less than as defined in the header  file.   By
			default	 the  next  available  unique  group ID in the
			valid range is allocated.  Group IDs in the range 0-99
			are reserved.

	      Allow the gid to be non-unique (that is, a duplicate).

       The  command  is	 aware	of NIS user entries.  Only local groups may be
       added with this command.	 Attempts to add an NIS group will  result  in
       an  error.  NIS groups must be administered from the NIS server.	 If is
       used on a system where NIS is installed, it may fail with the error

       (return value 9) if the group specified is not  present	in  the	 local
       file,  but is an NIS group (see group(4)).  NIS groups are also checked
       when verifying uniqueness of the new gid, which may result in the error

       (return value 4).

       The command exits with one of the following values:

	      No error.
	      Invalid command syntax.
	      Invalid argument supplied to an option.
	      gid  is not unique (when is not used).
		   is not unique.
	      Cannot modify the
	      file or
		   file busy. Another command may be modifying the file.
	      Unable to open
		   file or file is non-existent.

       Add the group to the file.

       Add the group to the file with the group ID as long as  no  group  cur‐
       rently exists with a group ID of

       Because many users may try to write the file simultaneously, a password
       locking mechanism was devised.  If this locking fails after  subsequent
       retrying, terminates.
