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.
