NAME [Toc] [Back]
nismatch, nisgrep - utilities for searching NIS+ tables
SYNOPSIS [Toc] [Back]
nismatch [ -AchMoPv ] key tablename
nismatch [ -AchMoPv ] colname=key... tablename
nismatch [ -AchMoPv ] indexedname
nisgrep [ -AchMov ] keypat tablename
nisgrep [ -AchMov ] colname=keypat... tablename
DESCRIPTION [Toc] [Back]
nismatch and nisgrep can be used to search NIS+ tables. The command
nisgrep differs from the nismatch command in its ability to accept
regular expressions keypat for the search criteria rather than simple
Because nisgrep uses a callback function, it is not constrained to
searching only those columns that are specifically made searchable at
the time of table creation. This makes it more flexible, but slower
In nismatch, the server does the searching; whereas in nisgrep, the
server returns all the readable entries and then the client does the
In both commands, the parameter tablename is the NIS+ name of the
table to be searched. If only one key or key pattern is specified
without the column name, then it is applied searching the first
column. Specific named columns can be searched by using the
colname=key syntax. When multiple columns are searched, only entries
that match in all columns are returned. This is the equivalent of a
logical join operation.
nismatch accepts an additional form of search criteria, indexedname,
which is a NIS+ indexed name of the form:
[ colname=value, ... ],tablename
Options [Toc] [Back]
-A All data. Return the data within the table and all of the data
in tables in the initial table's concatenation path.
-c Print only a count of the number of entries that matched the
-h Display a header line before the matching entries that contains
the names of the table's columns

-M Master server only. Send the lookup to the master server of the
named data. This guarantees that the most up to date information
is seen at the possible expense that the master server may be
-o Display the internal representation of the matching NIS+
-P Follow concatenation path. Specify that the lookup should follow
the concatenation path of a table if the initial search is
-v Verbose. Do not suppress the output of binary data when
displaying matching entries. Without this option, binary data is
displayed as the string *BINARY*.
RETURN VALUES [Toc] [Back]
0 Successfully matches some entries.
1 Successfully searches the table and no matches are found.
2 An error condition occurs. An error message is also printed.
EXAMPLES [Toc] [Back]
This example searches a table named passwd in the org_dir subdirectory
of the zotz.com. domain. It returns the entry that has the username
of skippy. In this example, all the work is done on the server.
nismatch name=skippy passwd.org_dir.zotz.com.
This example is similar to the one above except that it uses nisgrep
to find all users in the table named passwd that are using either
nisgrep 'shell=[ck]sh' passwd.org_dir.zotz.com.
EXTERNAL INFLUENCES [Toc] [Back]
NIS_PATH If this 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(1)).
WARNINGS [Toc] [Back]
HP-UX 11i Version 2 is the last HP-UX release on which NIS+ is
LDAP is the recommended replacement for NIS+. HP fully supports the
industry standard naming services based on LDAP.
