+NAME
+----
+nvme-nvm-id-ns - Send NVMe Identify NVM Command Set specific Namespace data structure, display structure
+
+SYNOPSIS
+--------
+[verse]
+'nvme nvm-id-ns' <device> [--uuid-index=<uuid-index> | -U <uuid_index>]
+ [--namespace-id=<NUM> | -n <NUM>]
+ [-v | --verbose]
+ [--output-format=<fmt> | -o <fmt>]
+
+DESCRIPTION
+-----------
+Identify NVM Command Set specific Namespace data structure for the specified
+NSID for the NVM Command Set specified in the CSI field.
+
+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 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.
+
+OPTIONS
+-------
+-n <NUM>::
+--namespace-id=<NUM>::
+ 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.
+
+-U <uuid-index>::
+--uuid-index=<uuid-index>::
+ UUID Index of the feature
+
+-v::
+--verbose::
+ Increase the information detail in the output.
+
+-o <format>::
+--output-format=<format>::
+ Set the reporting format to 'normal', 'json', or
+ 'binary'. Only one output format can be used at a time.
+
+EXAMPLES
+--------
+* Has the program interpret the returned buffer and display the known
+fields in a human readable format:
++
+------------
+# nvme nvm-id-ns /dev/nvme0n1
+------------
++
+
+* If using the character device or overriding namespace id:
++
+------------
+# nvme nvm-id-ns /dev/nvme0 -n 1
+# nvme nvm-id-ns /dev/nvme0n1 -n 1
+# nvme nvm-id-ns /dev/nvme0 --namespace-id=1
+------------
++
+* Have the program return the raw structure in binary:
++
+------------
+# nvme nvm-id-ns /dev/nvme0n1 -o binary > id_ns.raw
+# nvme nvm-id-ns /dev/nvme0n1 --output-format=binary > id_ns.raw
+------------
++
+It is probably a bad idea to not redirect stdout when using this mode.
+
+* Alternatively you may want to send the data to another program that
+can parse the raw buffer.
