+.sp
+For the NVMe device given, send an nvme rpmb command and provide the results\&.
+.sp
+The <device> parameter is mandatory and NVMe character device (ex: /dev/nvme0) must be specified\&. If the given device supports RPMB targets, command given with \-\-cmd or \-c option shall be sent to the controller\&. If given NVMe device doesn\(cqt support RPMB targets, a message indicating the same shall be printed along with controller register values related RPMB\&.
