Only view the CPU temperature from command `sensors`

  • 772

Ok, so when I run the command:

sensors

I get a truck load of info:

atk0110-acpi-0
Adapter: ACPI interface
Vcore Voltage:     +1.16 V  (min =  +0.85 V, max =  +1.60 V)
 +3.3 Voltage:     +3.39 V  (min =  +2.97 V, max =  +3.63 V)
 +5 Voltage:       +5.17 V  (min =  +4.50 V, max =  +5.50 V)
 +12 Voltage:     +12.36 V  (min = +10.20 V, max = +13.80 V)
CPU FAN Speed:    1906 RPM  (min =  600 RPM)
CHASSIS FAN Speed:   0 RPM  (min =  600 RPM)
CPU Temperature:   +31.0°C  (high = +60.0°C, crit = +95.0°C)  
MB Temperature:    +32.0°C  (high = +45.0°C, crit = +95.0°C)

What would the command be if I just wanted to see this:

CPU Temperature:   +31.0°C  (high = +60.0°C, crit = +95.0°C)

or better yet, just this:

CPU Temperature:   +31.0°C

    You can process the output of sensors command with grep and/or cut to format it the way you want.

    To get only the line reporting the CPU temperature you can use this (including the high and critical limits):

    sensors | grep -A 0 'CPU T'

    The following will give you only the temperature (with the °C suffix) :

    sensors | grep -A 0 'CPU T' | cut -c18-25

    This will give the output as you indicated at the end of your question:

    sensors | grep -A 0 'CPU T' | cut -c1-25

  2. The string below should work for you. grep -A[4] gives the next 4 lines The watch -d refreshes the changes and -d highlights the difference from the last refresh.

    watch -d 'sensors | grep 'CPU Temperature''

  3. Install the small apci package with the following command:

    sudo apt-get install acpi

    You will need to press Y for confirmation for the first time.

    Now to find the CPU temperature with this command:

    acpi -t
