+.SH "DESCRIPTION"
+.sp
+Identify NVM Command Set specific Namespace data structure for the specified NSID for the NVM Command Set specified in the CSI field\&.
+.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)\&.
+.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 <NUM>, \-\-namespace\-id=<NUM>
+.RS 4
+Use the provided namespace id for the command\&. If not provided, the namespace id of the block device will be used\&. If the command is issued to a non\-block device, the parameter is required\&.

+\-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\&.
