1 /OUTPUT
/OUTPUT=file-spec Controls where the output of the command is sent. If you do not specify a file name, the system uses the default name REGISTRY.LIS.
2 /WAIT
/WAIT=seconds (default = 90) /NOWAIT Specifies the maximum amount of time, in seconds, that you are willing to wait for command completion. If the Registry server does not complete the request in the specified interval, REG$CP returns REG-F-NORESPONSE. The default interval is 90 seconds. /NOWAIT is equivalent to specifying /WAIT=0, but there may still be a short wait period.
