i8kctl - Utility to get information, and set fans states
i8kctl [<param> [<args>]]
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.
