Usage:
  -d, --device <dev>  Use device <dev> instead of /dev/cec0
                      If <dev> starts with a digit, then /dev/cec<dev> is used.
  -D, --driver <driver>    Use a cec device with this driver name
  -a, --adapter <adapter>  Use a cec device with this adapter name
  -h, --help          Display this help message
  -n, --no-warnings   Turn off warning messages
  -T, --trace         Trace all called ioctls
  -v, --verbose       Turn on verbose reporting
  -w, --wall-clock    Show timestamps as wall-clock time (implies -v)
  -e, --exclusive     If specified, then the follower uses exclusive mode (CEC_MODE_EXCL_FOLLOWER)
  -m, --show-msgs     Show received messages
  -s, --show-state    Show state changes from the emulated device
  --service-by-dig-id Report digital services by digital ID instead of by channel
  --standby           Start in Standby state
  --toggle-power-status <secs>
                      Toggle the power status every <secs> seconds
  --ignore-standby <n>
                      Ignore every <n>th received Standby message
  --ignore-view-on <n>
                      Ignore every <n>th received Image/Text View On message
  -i, --ignore <la>,<opcode>
                      Ignore messages from logical address <la> and opcode
                      <opcode>. 'all' can be used for <la> or <opcode> to match
