.SH "DESCRIPTION"
.sp
For the NVMe device given, issues the Zone Management Send command with the Set Zone Descriptor Extenions action\&. The input will default to stdin\&. Alternatively, the data may come from a file that can be specified\&. The data length will automatically be calculated from the zns identify namesapce\&.
.SH "OPTIONS"
