nismatch(1) User Commands nismatch(1)NAME
nismatch, nisgrep - utilities for searching NIS+ tables
SYNOPSIS
nismatch [-AchMoPv] [-s sep] key tablename
nismatch [-AchMoPv] [-s sep] colname = key... tablename
nismatch [-AchMoPv] [-s sep] indexedname
nisgrep [-AchiMov] [-s sep] keypat tablename
nisgrep [-AchiMov] [-s sep] colname = keypat... tablename
DESCRIPTION
The utilities 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 text matches.
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,
than nismatch.
In nismatch, the server does the searching, whereas in nisgrep the
server returns all the readable entries and then the client does the
pattern-matching.
In both commands, the parameter tablename is the NIS+ name of the ta‐
ble to be searched. If only one key or key pattern is specified without
the column name, then it is applied searching the first column. Spe‐
cific named columns can be searched by using the colname=key syntax.
When multiple columns are searched, only entries that match in all col‐
umns 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
The following options are supported:
-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 search criteria.
-h Display a header line before the matching entries that
contains the names of the table's columns
-i Ignore upper/lower case distinction during comparisons.
-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 busy.
-o Display the internal representation of the matching
NIS+ object(s).
-P Follow concatenation path. Specify that the lookup
should follow the concatenation path of a table if the
initial search is unsuccessful.
-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.
-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*.
EXAMPLES
Example 1: Searching a table for a username
This example searches a table named passwd in the org_dir subdirec‐
tory of the zotz.com. domain. It returns the entry that has the user‐
name of skippy. In this example, all the work is done on the server:
example% nismatch name=skippy passwd.org_dir.zotz.com.
Example 2: Finding users using specific shells
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
ksh(1) or csh(1):
example% nisgrep 'shell=[ck]sh' passwd.org_dir.zotz.com.
ENVIRONMENT VARIABLES
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)).
EXIT STATUS
The following exit values are returned:
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.

attributes(5)DIAGNOSTICS
No memory An attempt to allocate some
memory for the search failed.
tablename is not a table The object with the name table‐
name was not a table object.
Can't compile regular expression The regular expression in key‐
pat was malformed.
column not found: colname The column named colname does
not exist in the table named
tablename.
NOTES
NIS+ might not be supported in future releases of the Solaris operating
system. Tools to aid the migration from NIS+ to LDAP are available in
the current Solaris release. For more information, visit
