"""Displays sensor temperature
Parameters:
* sensors.path: path to temperature file (default /sys/class/thermal/thermal_zone0/temp).
* sensors.match: (fallback) Line to match against output of 'sensors -u' (default: temp1_input)
* sensors.match_number: (fallback) which of the matches you want (default -1: last match).
