.SH "DESCRIPTION"
.sp
For the NVMe device given, sends an identify command for namespace list 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 starting namespace in the list always begins with 0 unless the \*(Aq\-\-namespace\-id\*(Aq option is given to override\&.
.sp
On success, the namespace array is printed for each index and nsid for a valid nsid\&.
.SH "OPTIONS"
.PP
\-n <nsid>, \-\-namespace\-id=<nsid>
.RS 4
Retrieve the identify list structure starting with the given nsid\&.
.RE
.PP
\-y <command_set_identifier>, \-\-csi=<command_set_identifier>
.RS 4
If this value is given, retrieve the identify list structure associated with the specified I/O command set\&.
.RE
.PP
\-a, \-\-all
.RS 4
Retrieve the identify list structure for all namespaces in the subsystem, whether attached or inactive\&.
.RE
.PP
\-o <format>, \-\-output\-format=<format>
.RS 4
Set the reporting format to
\fInormal\fR, or
\fIjson\fR\&. Only one output format can be used at a time\&.
