Utility for searching NIS+ tables.
nisgrep [ -A ] [ -c ] [ -h ] [ -M ] [ -o ] [ -P ] [ -s [sep ] ] [ -v ]
The nisgrep command 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 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
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.
example% 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 ksh or csh.
example% nisgrep 'shell=[ck]sh' passwd.org_dir.zotz.com.
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).
The niscat command, nisdefaults command, nisls command, and nistbladm command.
