# sensors
# Print sensors information

# By default, if possible, sensors(1) will provide temperature information in
# Celsius. Using the `-f` option, Fahrenheit can instead be used.
sensors -f

# Display sensor information in raw output, suitable for parsing.
sensors -u

# Using sensors(1) and Perl, output only the CPU's fan speed (RPM). May not
# work on all system's software and/or hardcore configurations.
sensors | perl -ne '/^cpu_fan/ && print((split(" "))[1])'
