Using the ndd Utility in Non-Interactive Mode

1. To modify a parameter value, use the -set option.

   If you invoke the ndd utility with the -set option, the utility passes value, which must be specified down to the named /dev/eri driver instance, and assigns it to the parameter:

   % ndd -set /dev/eri parameter value

1. To display the value of a parameter, specify the parameter name (and omit the value).

   When you omit the -set option, a query operation is assumed and the utility queries the named driver instance, retrieves the value associated with the specified parameter, and prints it:

   % ndd /dev/eri parameter
