NICKNAMES(5)		    BSD File Formats Manual		  NICKNAMES(5)

NAME
     nicknames — map nickname translation file for NIS (YP)

DESCRIPTION
     The ypcat(1), ypmatch(1), and ypwhich(1) commands reference NIS (YP) maps
     as specified by the user.	Occasionally it is desirable to use a short‐
     hand reference for a longer map name, hence the nicknames file, kept in
     “/var/yp/nicknames.”

     The format of the file is

	   nickname map

     one pair per line.	 The default installed nickname map is as follows:

	   passwd     passwd.byname
	   group      group.byname
	   networks   networks.byaddr
	   hosts      hosts.byname
	   protocols  protocols.bynumber
	   services   services.byname
	   aliases    aliases.byname
	   ethers     ethers.byname
	   master.passwd
		      master.passwd.byname

     A blank or incomplete nicknames file will affect any scripts which use
     nicknames for map lookup, whereas if the file is simply missing, the
     default compiled-in list will be used.

SEE ALSO
     ypcat(1), ypmatch(1), ypwhich(1)

HISTORY
     The nicknames file first appeared in Solaris 2.4.
