NAME
       groupadd - create a new group

SYNOPSIS
       groupadd [-g gid [-o]] [-r] [-f] [-K KEY=VALUE] group

DESCRIPTION
       The groupadd command creates a new group account using the values
       specified on the command line and the default values from the system.
       The new group will be entered into the system files as needed.

OPTIONS
       The options which apply to the groupadd command are:

       -f This option causes to just exit with success status if the specified
	  group already exists. With -g, if specified GID already exists,
	  other (unique) GID is chosen (i.e.  -g is turned off).

       -r This flag instructs groupadd to add a system account.	 The first
	  available gid lower than GID_MIN will be automatically selected
	  unless the -g option is also given on the command line. This is an
	  option added by Red Hat.

       -g GID
	  The numerical value of the group's ID. This value must be unique,
	  unless the -o option is used. The value must be non-negative. The
	  default is to use ID value equal to or greater than GID_MIN and
	  smaller than GID_MAX. Values between 0 and GID_MIN are typically
	  reserved for system accounts.

       -h, --help
	  Display help message and exit.

       -K KEY=VALUE
	  Overrides /etc/login.defs defaults (GID_MIN, GID_MAX and others).
	  Multiple -K options can be specified.

	  Example: Set the gid of range from 100 to 499.

	  # groupadd -K GID_MIN=100 -K GID_MAX=499 test

	  The new group "test" is added into /etc/group.

	   /etc/group test:x:105:


	  Note: This option does not work when arguments are separated by
	  comma.

	  (Example: -K GID_MIN=10,GID_MAX=499)

       -o This option permits to add group with non-unique GID.

FILES
       /etc/group
	  Group account information.

       /etc/gshadow
	  Secure group account information.

       /etc/login.defs
	  Shadow password suite configuration.

CAVEATS
       If the groupname already exists in an external group database such as
       NIS, groupadd will deny the group creation request.

EXIT VALUES
       The groupadd command exits with the following values:

       0  success

       2  invalid command syntax

       3  invalid argument to option

       4  GID not unique (when -o not used)

       9  group name not unique

       10 can't update group file
