domainname
—
set or print name of current YP/NIS domain
The
domainname
utility prints the name of the
current YP/NIS domain. The super-user can set the domain name by supplying an
argument; this is usually done with the
nisdomainname variable in the
/etc/rc.conf file, normally run at boot
time.
The YP/NIS (formerly ``Yellow Pages'' but renamed for legal reasons) domain name
does not necessarily have anything to do with the Domain Name System domain
name, although they are often set equal for administrative convenience.

The
domainname
command appeared in
FreeBSD 1.1, based on a similar command in
SunOS.
