When I login as root user into my Raspberry Pi, then I query for temperature using this command:

pi@raspberrypi ~ $ /sys/class/thermal/thermal_zone0/mode

-bash: /sys/class/thermal/thermal_zone0/mode: Permission denied

I think I've broken down something. How can I repair?

You are attempting to execute that file which is not possible.

You want to view the content of the file which you can do like this:

$ cat /sys/class/thermal/thermal_zone0/mode 

And if you want the temperature:

$ cat /sys/class/thermal/thermal_zone0/temp

You need the divide the number you get by 1000 to get degrees C

  • @Fred Odd, somehow that got cut. I edited the answer. – Craig Apr 18 '14 at 14:37
