+.SH "DESCRIPTION"
+.sp
+Submits an arbitrary NVMe IO command and returns the applicable results\&. This may be the simply the command\(cqs result and status, or may also include a buffer if the command returns one\&. This command does no interpretation of the opcodes or options\&.
+.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 returned structure (if applicable) may be returned in one of several ways depending on the option flags; the structure may printed by the program as a hex dump, or may be returned as a raw buffer printed to stdout for another program to parse\&.
+.SH "OPTIONS"
+.PP
+\-o <opcode>, \-\-opcode=<opcode>
+.RS 4
+The NVMe opcode to send to the device in the command
+.RE
+.PP
+\-f <flags>, \-\-flags=<flags>
+.RS 4
+The NVMe command flags to send to the device in the command
+.RE
+.PP
+\-R <rsvd>, \-\-rsvd=<rsvd>
+.RS 4
+The value for the reserved field in the command\&.
+.RE
+.PP
+\-n <nsid>, \-\-namespace\-id=<nsid>
+.RS 4
+The value for the ns\-id in the command\&. Defaults to
+\fI0\fR\&.
+.RE
+.PP
+\-\-cdw[2\-3,10\-15]=<cdw>
+.RS 4
+Specifies the command dword value for that specified entry in the command
+.RE
+.PP
+\-r, \-\-read, \-w, \-\-write
+.RS 4
+Used for the data\-direction for the command and required for commands sending/receiving data\&. Don\(cqt use both read and write at the same time\&.
+.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
+\-l <data\-len>, \-\-data\-len=<data\-len>
+.RS 4
+The data length for the buffer used for this command\&.
+.RE
+.PP
+\-m <data\-len>, \-\-metadata\-len=<data\-len>
+.RS 4
+The metadata length for the buffer used for this command\&.
+.RE
+.PP
+\-s, \-\-show\-cmd
+.RS 4
+Print out the command to be sent\&.
+.RE
+.PP
+\-d, \-\-dry\-run
+.RS 4
+Do not actually send the command\&. If want to use \-\-dry\-run option, \-\-show\-cmd option
+\fImust\fR
+be set\&. Otherwise \-\-dry\-run option will be
+\fIignored\fR\&.
+.RE
+.PP
+\-b, \-\-raw\-binary
+.RS 4
+Print the raw returned buffer to stdout if the command returns data or a structure\&.
+.RE
+.PP
+\-p <prefill>, \-\-prefill <prefill>
+.RS 4
+Prefill the buffer with a predetermined byte value\&. Defaults to 0\&. This may be useful if the data you are writing is shorter than the required buffer, and you need to pad it with a known value\&. It may also be useful if you need to confirm if a device is overwriting a buffer on a data\-in command\&.
