Watch that command

I was reminded to day of how useful watch is. I omitted it from my previous list of important and useful commands because I rarely use it. But today I had George open on the bench and was finding out what fan connectors on the motherboard corresponded to which speed sensor, as reported by lm-sensors.

watch -n 0 "sensors w83793-i2c-0-2f | grep fan"

Then, as I plugged and unplugged a 3-wire fan here and there, I could see on screen what was going on. This is especially important, cause you don't want to unplug the CPU fan for any length of time.

FYI, the sensor:fan port mapping for a DSBV-DX is as follows:

fan1  CPU_FAN1

fan2  CPU_FAN2

fan3  FRNT_FAN1

fan4  FRNT_FAN2

fan5  FRNT_FAN3

fan6  FRNT_FAN4

fan7  REAR_FAN1

fan8  REAR_FAN2

fan9  FBD_FAN1

fan10 N/C

fan11 N/C

fan12 N/C
