                   [--version] DEVICE
  where:
    --address=A,A...|-a A,A...    comma separated logical block addresses
                                  one or more, assumed to be decimal
    --address=-|-a -    read stdin for logical block addresses
    --dummy|-d          prepare but do not execute REASSIGN BLOCKS command
    --eight=0|1
      -e 0|1            force eight byte (64 bit) lbas when 1,
                        four byte (32 bit) lbas when 0 (def)
    --grown|-g          fetch grown defect list length, don't reassign
    --help|-h           print out usage message
    --hex|-H            print response in hex (for '-g' or '-p')
    --longlist=0|1
       -l 0|1           use 4 byte list length when 1, safe to ignore
                        (def: 0 (2 byte list length))
    --primary|-p        fetch primary defect list length, don't reassign
    --verbose|-v        increase verbosity
    --version|-V        print version string and exit

Perform a SCSI REASSIGN BLOCKS command (or READ DEFECT LIST)
