+.SH "DESCRIPTION"
+.sp
+Submits an NVMe Directive Receive admin command and returns the applicable results\&. This may be the combination of directive type, and operation, as well as number of requested resource if specific operation needs it\&.
+.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 directive\(cqs parameter structure (if applicable) is returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format if it is a known structure, displayed in hex, or the raw buffer may be printed to stdout for another program to parse\&.

+
+DESCRIPTION
+-----------
+Submits an NVMe Directive Receive admin command and returns the applicable
+results. This may be the combination of directive type, and operation, as
+well as number of requested resource if specific operation needs it.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned directive's parameter structure (if applicable) is
+returned in one of several ways depending on the option flags; the
+structure may parsed by the program and printed in a readable format
+if it is a known structure, displayed in hex, or the raw buffer may be
+printed to stdout for another program to parse.

+DESCRIPTION
+-----------
+Submits an NVMe Directive Send admin command and returns the applicable
+results. This may be the combination of directive type, and operation, as
+well as target directive and its enable/disable status of the operation,
+if specific operation needs it.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned directive's parameter structure (if applicable) is
+returned in one of several ways depending on the option flags; the
+structure may parsed by the program and printed in a readable format
+if it is a known structure, displayed in hex, or the raw buffer may be
+printed to stdout for another program to parse.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+ Retrieve the feature for the given nsid. This is optional and
+ most features do not use this value.
+
+-D <dtype>::
+--dir-type=<dtype>::
+ Directive type
+
+-S <dspec>::
+--dir-spec=<dspec>::
+ Directive specific
+
+-O <doper>::
+--dir-oper=<doper>::
+ Directive operation
+
+-T <tdir>::
+--target-dir=<nsr>::
+ Target directive of the operation
+
+-e <endir>::
+--endir=<endir>::
+ Target directive enable(1) or disable (0) operation

+|==================
+
+-l <data-len>::
+--data-len=<data-len>::
+ The data length for the buffer returned for this feature. Most
+ known features do not use this value. The exception is LBA
+ Range Type
+
+-b::
+--raw-binary::
+ Print the raw receive buffer to stdout if the command returns
+ a structure.
+
+-H::
+--human-readable::
+ Print the decoded receive buffer to stdout if the command returns
+ a structure.
+
+EXAMPLES
+--------
+* Enable streams directive :
++
+------------
+# nvme dir-send /dev/nvme0n1 --dir-type 0 --dir-oper 1 --target-dir 1 --endir 1
+------------
++
+
+* Disable streams directive :
++
+------------
+# nvme dir-send /dev/nvme0n1 --dir-type 0 --dir-oper 1 --target-dir 1 --endir 0
+------------
++
+
+* Release all allocated streams resource :
++
+------------
+# nvme dir-send /dev/nvme0n1 --dir-type 1 --dir-oper 2
+------------
++
+
+* Release stream ID 3 :
++
+------------
+# nvme dir-send /dev/nvme0 --dir-type 1 --dir-oper 1 --dir-spec 3
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.
