Want to check the CPU temperature in the Ubuntu terminal?

Well, there are multiple tools to do so and in this tutorial, I will introduce 4 such tools to check CPU temperature in an Ubuntu terminal:

  1. lm-sensors
  2. Glances
  3. hardinfo
  4. i7z

So let's start with the first one.

1. Using the lm-sensors utility

By far this is the most popular utility to check the temperature in Linux and serves as a backend for so many GUI utilities that lets you check CPU temps.

Being super popular, lm-sensors is available in the default repository of Ubuntu and can easily be installed with the following command:

sudo apt install lm-sensors

Once done, use the following command to detect the sensors of your system:

sudo sensors-detect

After you execute the above command, it will ask you several questions for various adapters whether you want to check their temperature or not.

I would recommend going with the default opinions (press the Enter key for that):

Now, you can execute the sensors command to check the temperature:

If your CPU reaches a high temperature, check if some program is consuming too much processing power. Validate if it is normal. Cleaning your system for dust also helps in reducing the overheating.

2. Using the Glances utility

Glances does much more than just checking the CPU temperature.

It is more of an alternative to htop and lets you monitor network, memory utilization, and much more.

Like lm-sensors, glances is available in the default repository of Ubuntu and can be installed with the following command:

sudo apt install glances

Once done, start the glances utility:

3. Using the hardinfo utility

The hardinfo is a lightweight benchmarking utility and being a benchmarking utility, it is a no-brainer that you can also use it to check CPU temperature.

To install hardinfo in Ubuntu, use the following command:

sudo apt install hardinfo

Once done, execute the following command to

hardinfo -rma

4. Using the i7z utility

The i7z utility provides detailed information about the Intel i3, i5, and i7 processors including the CPU temperature.

To install i7z, all you have to do is execute the following command:

sudo apt install i7z

Once done, start the i7z utility to display CPU temperature:

sudo i7z

(give it a few seconds and soon you'll see live temperature):

Pretty easy. Right?

Final words...

Here are various ways for getting the processor information in Ubuntu command line.

This was a quick tutorial showing multiple ways to check the CPU temperature in the Ubuntu terminal in the least complex way possible.

I hope checking CPU temperature is no longer a complex task for you.
