.SH "DESCRIPTION"
.sp
For the NVMe device given, issues the Zone Management Send command with the Set Zone Descriptor Extensions 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 namespace\&.
.SH "OPTIONS"
.PP
\-n <NUM>, \-\-namespace\-id=<NUM>
.RS 4
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\&.
