NAME
       groupadd - create a new group

SYNOPSIS
       groupadd [-g GID [-o]] [-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).

       -g GID
	  The numerical value of the groups ID. This value must be unique,
	  unless the -o option is used. The value must be non-negative. The
	  default is to use the smallest ID value greater than 999 and greater
	  than every other group. Values between 0 and 999 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: -K GID_MIN=100
	   -K GID_MAX=499

	  Note: -K GID_MIN=10,GID_MAX=499 doesnt work yet.

       -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
       Groupnames must begin with a lower case letter or an underscore, and
       only lower case letters, underscores, dashes, and dollar signs may
       follow. In regular expression terms: [a-z_][a-z0-9_-]*[$]

       Groupnames may only be up to 16 characters long.

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

       Groupnames may only be up to 16 characters long.

       0
	  success
