  -b   --drivebase   :  display database file content that allow hddtemp to
                        recognize supported drives.

                        Useful to find a value that seems to match the
                        temperature and/or to send me a report.
                        (done for every drive supplied).
  -d   --daemon      :  run hddtemp in TCP/IP daemon mode (port 7634 by default.)
  -f   --file=FILE   :  specify database file to use.
  -F   --foreground  :  don't daemonize, stay in foreground.
  -l   --listen=addr :  listen on a specific interface (in TCP/IP daemon mode).
  -n   --numeric     :  print only the temperature.
  -p   --port=#      :  port to listen to (in TCP/IP daemon mode).
  -s   --separator=C :  separator to use between fields (in TCP/IP daemon mode).
  -S   --syslog=s    :  log temperature to syslog every s seconds.
  -u   --unit=[C|F]  :  force output temperature either in Celsius or Fahrenheit.
  -q   --quiet       :  do not check if the drive is supported.
  -v   --version     :  display hddtemp version number.
  -w   --wake-up     :  wake-up the drive if need.
  -4                 :  listen on IPv4 sockets only.
  -6                 :  listen on IPv6 sockets only.
