DESCRIPTION
 ypcat prints out the values of all keys from the NIS database specified by 
mapname, which may be a map name or a map nickname.
The options are as follows:
- 
-b num_retry
- 
Do not wait infinite time for the ypserver to come up. Retry only the specified number of times. See yp_setbindtries(3) for explanation. The valid range is limited from 0 to 65535 by this program.
- 
-d domainname
- 
Specify a domain other than the default domain.
- 
-k
- 
Display map keys. This option is useful with maps in which the values are null or the key is not part of the value.
- 
-s
- 
When printing the value of a key, compress all whitespace characters to a single space. Useful when values contain newlines.
- 
-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).
