.SH DESCRIPTION
Without  an  argument,
.B domainname
displays the name of the current NIS domainname of the system.
.B domainname
uses the
.BR getdomainname (2)
function for getting the domainname,
.B nisdomainname
and
.B ypdomainname
are using
.BR yp_get_default_domain (3).
.PP
Only the super-user can set the name of the domain by specifying the new
.B domain
as an argument. All three programs uses
.BR setdomainname (2)
for this. Bear in mind, that already running programs may continue to
use the old domainname.
