groupadd [options] group — shadow-utils

Synopsis

/usr/sbin stdin stdout - file -- opt --help --version

The groupadd command creates a new group. In most cases, you should use the -f option to prevent duplicate groups from being created:

# groupadd -f friends

Useful options
-g gid	Specify your own numeric group ID instead of letting groupadd choose one.
-f	If the specified group exists already, complain and exit.
