About niscat

On Solaris, the niscat command displays NIS+ (Network Information Service) tables and objects.

Description

In the first syntax form above, niscat displays the contents of the NIS+ tables named by tablename.

In the second syntax form, niscat displays the internal representation of the NIS+ objects named by name.

niscat syntax

niscat [-AhLMv] [-s sep] tablename...
niscat [-ALMP] -o name...

Options

-A Display the data within the table and all of the data in tables in the initial table's concatenation path.
-h Display the header line prior to displaying the table. The header consists of the '#' (hash) character followed by the name of each column. The column names are separated by the table separator character.
-L Follow links. When this option is specified, if tablename or name names a LINK type object, the link is followed and the object or table named by the link is displayed.
-M Master server only. This option specifies that the request should be sent to the master server of the named data. This guarantees that the most up-to-date information is seen at the possible expense of increasing the load on the master server and increasing the possibility of the NIS+ server being unavailable or busy for updates.
-P Follow concatenation path. This option specifies that the request should follow the concatenation path of a table if the initial search is unsuccessful. This option is only useful when using an indexed name for name and the -o option.
-v Display binary data directly. This option displays columns containing binary data on the standard output. Without this option binary data is displayed as the string "*BINARY*".
-o name Display the internal representation of the named NIS+ object(s). If name is an indexed name (see nismatch), then each of the matching entry objects is displayed. This option is used to display access rights and other attributes of individual columns.
-s sep This option specifies the character to use to separate the table columns. If no character is specified, the default separator for the table is used.

Environment

If the NIS_PATH environment variable is set, and the NIS+ table name is not fully qualified, each directory specified will be searched until the table is found (see nisdefaults).

niscat examples

niscat -h hosts.org_dir

Display the contents of the host table. Output will resemble the following:

# cname    name       addr               comment
client1    client1    129.144.201.100    Joe Smith
crunchy    crunchy    129.144.201.44     Jane Smith
crunchy    softy      129.144.201.44

If the user has insufficent permissions to view the contents of any given field or entry, the string "*NP*" will be printed.

nisdefaults — Display NIS+ default values.
nismatch — Utilities for searching NIS+ tables.
nistbladm — Administer NIS+ tables.
