This looks like it might be quite useful for others as well. Wonder if it would make sense to integrate it info fancontrol and/or pwmconfig.

Not that I care much, it is just odd to have such a script with an ending of .txt.

For a "final" code version, it would be sufficient to calculate the average after the loop. But then you would have to check for $count == 0, so I am not sure if it would be worth it. > if [ $DEGUG = 1 ]; then > echo $summation > echo $maximum > echo $average > echo $count > echo "-----" > fi > done > # fancontrol output format > echo "($maximum * 1000)/1" | bc > "$FILE_MAX" > echo "($average * 1000)/1" | bc > "$FILE_AVG" "echo $(($average * 1000))" seems to work as well and would be a bit simpler. What is the "/1" for, anyway ? bc doesn't seem to need it. Also, you are loosing precision because average is calculated (and rounded down) first. You could avoid that with "echo $(($average * 1000 / $count))" if you check for the $count==0 case. But then that doesn't really make much of a difference, so I am not sure if it would be worth it either. > sleep 45 > done > > exit' | tee /usr/local/bin/pct-fancontrol-hddtemp > > chown root:root /usr/local/bin/pct-fancontrol-hddtemp > chmod 755 /usr/local/bin/pct-fancontrol-hddtemp > ls -hal /usr/local/bin/pct-fancontrol-hddtemp > cat /usr/local/bin/pct-fancontrol-hddtemp > > #----------------------------------------------------------------------- > > /usr/local/bin/pct-fancontrol-hddtemp & > cat /var/lib/pct-fancontrol-hddtemp/pct-fancontrol-hddtemp-maximum > cat /var/lib/pct-fancontrol-hddtemp/pct-fancontrol-hddtemp-average > cat /var/lib/pct-fancontrol-hddtemp/* > > watch cat /var/lib/pct-fancontrol-hddtemp/* > > #----------------------------------------------------------------------- > > vim /etc/fancontrol > INTERVAL=10 > DEVPATH=hwmon0=devices/platform/it87.552 > DEVNAME=hwmon0=it8720 > FCTEMPS=hwmon0/device/pwm2=/var/lib/pct-fancontrol-hddtemp/pct-fancontrol-hddtemp-maximum hwmon0/device/pwm1=hwmon0/device/temp2_input > FCFANS=hwmon0/device/pwm2=hwmon0/device/fan2_input hwmon0/device/pwm1=hwmon0/device/fan1_input > MINTEMP=hwmon0/device/pwm2=41 hwmon0/device/pwm1=35 > MAXTEMP=hwmon0/device/pwm2=51 hwmon0/device/pwm1=55 > MINSTART=hwmon0/device/pwm2=58 hwmon0/device/pwm1=70 > MINSTOP=hwmon0/device/pwm2=58 hwmon0/device/pwm1=66 > > /etc/init.d/fancontrol restart > > #----------------------------------------------------------------------- > > /etc/init.d/fancontrol stop > > whereis fancontrol > file /usr/sbin/fancontrol > > bash -x /usr/sbin/fancontrol > > #----------------------------------------------------------------------- > > vim /etc/rc.local > /usr/local/bin/pct-fancontrol-hddtemp > Might be better to add a startup script in /etc/init.d and/or /etc/rc*.d and make sure it runs before fancontrol is started. > cat /etc/rc.local > > #----------------------------------------------------------------------- > > ps aux | grep fancontrol > > #----------------------------------------------------------------------- _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
