ypcat - print values in a NIS data base
ypcat [ -kt ] [ -d domainname ] mname
ypcat -x
ypcat prints out values in a Network Information Service ( NIS ) map specified by mname, which may be either a map name or a map nickname . Since ypcat uses the NIS service, no NIS server is specified.
To look at the network-wide password database, passwd.byname, (with the nickname passwd). type in:
ypcat passwd
NIS service.
|
-k |
Display the keys for those maps in which the values are null or the key is not part of the value. | ||
|
-t |
Inhibit translation of mname to map name. For example, ’ypcat -t passwd’ will fail because there is no map named passwd, whereas ’ ypcat passwd ’ will be translated to ’ypcat passwd.byname’. |
-d domainname
Specify a domain other than the default domain. The default domain is returned by domainname.
|
-x |
Display the map nickname table. This lists the nicknames (mnames) the command knows of, and indicates the mapname associated with each nickname. |

The Network Information Service ( NIS ) was formerly known as Yellow Pages ( YP ). The functionality of the two remains the same; only the name has changed.
