DESCRIPTION
 ypmatch prints out the values of one or more keys from the NIS database specified by 
mapname, which may be a map name or a map nickname.
The options are as follows:
- 
-d domainname
 
- 
Specify a domain other than the default domain.
 
- 
-k
 
- 
Print the map key followed by a colon, before printing key value. This option is useful with maps in which the values are null or the key is not part of the value.
 
- 
-t
 
- 
Inhibit translation of map nicknames to their corresponding map names.
 
- 
-x
 
- 
Display the map nickname table, found in /var/yp/nicknames. A built-in default translation table is used if /var/yp/nicknames does not exist (see nicknames(5) for details).
 
- 
-z
 
- 
Append a NUL character at the end of the key when doing the lookup. This is useful for mail.aliases maps, which include a trailing NUL in the keys.
