.SH "DESCRIPTION"
.sp
Send a NVMe\-MI Send command to the specified device, return results\&.
.sp
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0) or block device (ex: /dev/nvme0n1)\&.
.sp
On success it returns 0, error code otherwise\&.
.SH "OPTIONS"
.PP
\-O <opcode>, \-\-opcode=<opcode>
.RS 4
The NVMe\-MI opcode to send to the device in the command
.RE
.PP
\-n <nsid>, \-\-namespace\-id=<nsid>
.RS 4
The value for the ns\-id in the command\&.
.RE
.PP
\-l <data\-len>, \-\-data\-len=<data\-len>
.RS 4
The data length for the buffer used for this command\&.
.RE
.PP
\-m <nmimt>, \-\-nmimt=<nmimt>
.RS 4
The value for the NVMe\-MI message type in the command\&.
.RE
.PP
\-0 <nmd0>, \-\-nmd0=<nmd0>
.RS 4
The value for the NVMe management request dword 0 in the command\&.
.RE

.RS 4
The value for the NVMe management request dword 1 in the command\&.
.RE
.PP
\-i <file>, \-\-input\-file=<file>
.RS 4
If the command is a data\-out (write) command, use this file to fill the buffer sent to the device\&. If no file is given, assumed to use STDIN\&.
.RE
.PP
\-o <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR,
