              [--vpd] DEVICE
  where:
    --ata|-a        treat DEVICE as (directly attached) ATA device
    --block=0|1     0-> open(non-blocking); 1-> open(blocking)
      -B 0|1        (def: depends on OS; Linux pt: 0)
    --cmddt|-c      command support data mode (obsolete, see sg_opcodes)
    --cns=CNS       value for NVMe Identify command
    --descriptors|-d    display standard inquiry version descriptors
    --export|-u     SCSI_IDENT_<assoc>_<type>=<ident> output format.
                    Defaults to device id page (0x83) if --page not given,
                    only supported for VPD pages 0x80 and 0x83
    --extended|-E|-x    decode extended INQUIRY data VPD page (0x86)
    --force|-f      skip VPD page 0 check; directly fetch requested page
    --help|-h       print usage message then exit
    --hex|-H        output response in hex
    --id|-i         decode device identification VPD page (0x83)
    --inhex=FN|-I FN    read ASCII hex from file FN instead of DEVICE;
                        if used with --raw then read binary from FN
    --json[=JO]|-j[=JO]    output in JSON instead of plain text
                          Use --json=? for JSON help
    --js-file=JFN|-J JFN    JFN is a filename to which JSON output is
                            written (def: stdout); truncates then writes
    --len=LEN|-l LEN    requested response length (def: 0 -> fetch 36
                        bytes first, then fetch again as indicated)
    --long|-L       supply extra information on NVMe devices
    --maxlen=LEN|-m LEN    same as '--len='
    --old|-O        use old interface (use as first option)
    --only|-o       for std inquiry do not fetch serial number vpd page;
                    for NVMe device only do Identify controller
    --page=PG|-p PG     Vital Product Data (VPD) page number or
                        abbreviation (opcode number if '--cmddt' given)
    --quiet|-q      suppress some decoding and error output
    --raw|-r        output response in binary (to stdout)
    --sinq_inraw=RFN|-Q RFN    read raw (binary) standard INQUIRY
                               response from the RFN filename
    --vendor|-s     show vendor specific fields in std inquiry
    --verbose|-v    increase verbosity
    --version|-V    print this utility's version string then exit
    --vpd|-e        vital product data (set page with '--page=PG')

Sends a SCSI INQUIRY command to the DEVICE and decodes the response.
Alternatively it decodes the INQUIRY response held in file FN. If no
options given then it sends a 'standard' INQUIRY command to DEVICE. Can
list VPD pages with '--vpd' or '--page=PG' option.
