Usage: sg_turs [--ascq=ASC[,ASQ]] [--delay=MS] [--help] [--low]
               [--number=NUM] [--num=NUM] [--progress] [--time]
               [--timeout=SE] [--verbose] [--version] DEVICE
  where:
    --ascq=ASC[,ASQ] |    check sense from TUR for match on ASC[,ASQ]
        -a ASC[,ASQ]      exit status 36 if sense code match
    --delay=MS|-d MS    delay MS milliseconds before sending each tur
    --help|-h        print usage message then exit
    --low|-l         use low level (sg_pt) interface for speed
    --number=NUM|-n NUM    number of test_unit_ready commands (def: 1)
    --num=NUM|-n NUM       same action as '--number=NUM'
    --old|-O         use old interface (use as first option)
    --progress|-p    outputs progress indication (percentage) if available
                     waits 30 seconds before TUR unless --delay=MS given
    --time|-t        outputs total duration and commands per second
    --timeout SE |-T SE    command timeout on each test_unit_ready command
                           (def: 0 which is mapped to 60 seconds)
    --verbose|-v     increase verbosity
    --version|-V     print version string then exit

Performs a SCSI TEST UNIT READY command (or many of them).
This SCSI command is often known by its abbreviation: TUR .
