Manual Pages  — DOMAINNAME


domainname – set or print name of current YP/NIS domain



domainname [ypdomain]


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.


getdomainname(3), rc.conf(5)


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

This philosophy, in the hands of amateurs, leads to inexplicably mind-numbing botches like the existence of two programs, “head” and “tail,” which print the first part or the last part of a file, depending. Even though their operations are duals of one another, “head” and “tail” are different programs, written by different authors, and take different options!
