                   DEVICE
  where:
    --alpha|-a      output list of operation codes sorted alphabetically
    --compact|-c    more compact output
    --enumerate|-e    use '--opcode=' and '--pdt=' to look up name,
                      ignore DEVICE
    --help|-h       print usage message then exit
    --hex|-H        output response in hex, use -HHH for hex
                    suitable for later use of --inhex= option
    --inhex=FN|-i FN    contents of file FN treated as hex and used
                        instead of DEVICE which is ignored
    --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
    --mask|-m       show cdb usage data (a mask) when all listed
    --mlu|-M        show MLU bit when all listed
    --no-inquiry|-n    don't output INQUIRY information
    --opcode=OP[,SA]|-o OP[,SA]    opcode (OP) and service action (SA)
    --pdt=DT|-p DT    give peripheral device type for '--no-inquiry',
                      '--enumerate' and '--inhex=FN'
    --raw|-r        output response in binary to stdout unless --inhex=FN
                    is given then FN is parsed as binary instead
    --rctd|-R       set RCTD (return command timeout descriptor) bit
    --repd|-q       set Report Extended Parameter Data bit, with --tmf
    --rep-opts=RO|-Q RO    set Reporting Options field in cdb
    --sa=SA|-s SA    service action in addition to opcode
    --tmf|-t        output list of supported task management functions
    --unsorted|-u    output list of operation codes as is
                     (def: sort by opcode (then service action))
    --verbose|-v    increase verbosity
    --old|-O        use old interface (use as first option)
    --version|-V    print version string then exit

Performs a SCSI REPORT SUPPORTED OPERATION CODES or a REPORT SUPPORTED
TASK MANAGEMENT FUNCTIONS command. All values are in decimal by default,
prefix with '0x' or add a trailing 'h' for hex numbers.
