If given, NVM set + identifier whose entry is to be in result data will be greater than or + equal to this value. + +-o :: +--output-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 id-nvmset /dev/nvme0 +------------ ++ + +* Have the program return the raw structure in binary: ++ +------------ +# nvme id-nvmset /dev/nvme0 --output-format=binary > id_nvmset.raw +# nvme id-nvmset /dev/nvme0 -o binary > id_nvmset.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. ++ +------------ +# nvme id-nvmset /dev/nvme0 -o binary | nvme_parse_id_nvmset +------------ ++ +The parse program in the above example can be a program that shows the +structure in a way you like. The following program is such an example +that will parse it and can accept the output through a pipe, `'|'`, +as shown in the above example, or you can `'cat'` a saved output buffer to it. +------------ + +NVME +---- +Part of the nvme-user suite -- cgit v1.2.3
