+.SH "DESCRIPTION"
+.sp
+For the NVMe device given, sends an identify for a list of namespace identification descriptor structures command and provides the result and returned 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)\&. If the character device is given, the \*(Aq\-\-namespace\-id\*(Aq option is mandatory, otherwise it will use the ns\-id of the namespace for the block device you opened\&. For block devices, the ns\-id used can be overridden with the same option\&.
+.sp
+On success, the structure may be returned in one of several ways depending on the option flags; the structure may be parsed by the program or the raw buffer may be printed to stdout\&.
+.SH "OPTIONS"
+.PP
+\-n <nsid>, \-\-namespace\-id=<nsid>
+.RS 4
+Retrieve the identify namespace identification descriptor structure for the given nsid\&. This is required for the character devices, or overrides the block nsid if given\&.
+.RE
+.PP
+\-b, \-\-raw\-binary
+.RS 4
+Print the raw buffer to stdout\&. Structure is not parsed by program\&.
+.RE
+.PP
+\-o <format>, \-\-output\-format=<format>
+.RS 4
+Set the reporting format to
+\fInormal\fR,
+\fIjson\fR, or
+\fIbinary\fR\&. Only one output format can be used at a time\&.
