ERROR: Invalid command line: Unknown option: --
Usage: thinkfan [-hnqzD [-b BIAS] [-c CONFIG] [-s SECONDS] [-p [SECONDS]]]
-h This help message
-s Maximum cycle time in seconds (Integer. Default: 5)
-b Floating point number (-10 to 30) to control rising temperature
exaggeration (see README). Default: 5.0
-c Load different configuration file (default: /etc/thinkfan.conf)
-q Be more quiet. Can be specified up to three times so that only errors
are logged.
-v Enable verbose logging (e.g. log temperatures continuously).
-p Use the pulsing-fan workaround (for worn out fans). Takes an optional
floating-point argument (0 ~ 10s) as depulsing duration. Default 0.5s.
-d Don't read S.M.A.R.T. temperature from sleeping disks
-D DANGEROUS mode: Disable all sanity checks. May result in undefined
behaviour!
Unless you want to write a system service for it, I'd figure out where
there's a thinkfan.conf file (we don't seem to have it installed with
the package) and run 'sudo -E thinkfan -c /path/to/thinkfan.conf'
