NAME

       i8kctl - Utility to get information, and set fans states

SYNOPSIS

       i8kctl [<param> [<args>]]

DESCRIPTION

       The  i8kctl can be used to retrieve the information listed below. It does that by means of
       querying the system  through  the  dell-smm-hwmon  kernel  module.  When  invoked  without
       arguments  it reports all the information at once in one line of text.  The information is
       the same as the file /proc/i8k.

              1.  i8k output format version
              2.  Dell bios version
              3.  service tag (later 'machine id')
              4.  cpu temperature
              5.  left fan status
              6.  right fan status
              7.  left fan speed
              8.  right fan speed
              9.  ac power status
              10. fn buttons status

       The following parameters select one of the information:  version,  bios,  id,  temp,  fan,
       speed, ac and fn.

       Some examples of usage and output are below.

              $ i8kctl
              1.0 A17 B5W123K 52 2 1 8040 6420 1 2

              $ i8kctl temp
              52

              $ i8kctl fan
              2 1

       The  fan parameter accepts two optional arguments for the fans states. The state arguments
       can be:

              0  turn the fan off
              1  set low speed
              2  set high speed
              -  don't change the state of this fan

       And the following is an example of usage:

              $ i8kctl fan - 2

       This sets the right fan to high speed and leaves the left unchanged.  It should  be  noted
       that  if  the  i8kmon(1) daemon is used to control the fans, setting the speed with i8kctl
       fan is pointless since the daemon override regularly the speed with its own value.

       If i8kctl fan is invoked without the optional  arguments,  the  states  of  the  fans  are
       returned, and the output may contains a -1 which indicates that the corresponding fan does
       not exist.
