.SH "DESCRIPTION"
.sp
For the NVMe device given, send an identify command and return the Identify I/O Command Set data structure\&.
.sp
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
.SH "OPTIONS"
.PP
\-c <cntid>, \-\-controller\-id=<cntid>
.RS 4
Retrieve the identify I/O Command set data structure for the given cntid\&. If this value is not given, cntid will be 0xffff\&.
