Hi
Some of my longer sensor labels were causing an UNKNOWN status in the plugin. Some digging showed that the output from the sensors command wrapped to a new line and was being parsed to the while loop, on line 390, without the value of the sensor.
A quick and dirty hack for me was to re-format the output before it entered the loop:
$command = "$sensors_bin -A | perl -p -e 's/:\n/:/g' | grep :";
Someone with better perl knowledge could probably find a more elegant solution.

Hi and thanks for your work with this plugin!
I recently upgraded a server with Debian Jessie to Debian Stretch and I am not able to take sensor readings with check_lm_sensors:

So it seems the name file has been moved up from the device subfolder.
Obviously the old location might still be in use somewhere else so both should be checked.

Hi,
Wenn I try to use check_lm_sensors I got this error.[[BR]]# ./check_lm_sensors --list[[BR]]Undefined subroutine &main::unknown called at ./check_lm_sensors line 345.
Copied from original issue: matteocorti/nagios_plugins#30
I finally updated from 3.1.1 to 4.1.1, and it seems my CPU core temperature sensors are not available anymore.
