How to check CPU temperature on Ubuntu Linux

To check the CPU temperature on an Ubuntu Linux system, you can use the sensors command. This command displays temperature sensor information for the system, including the CPU temperature.

To check the CPU temperature, open a terminal window and run the sensors command.

For example:

sensors

This will display a list of temperature sensors on the system, along with their current readings.

The output of the sensors command may vary depending on the hardware and sensors on your system. However, you should see a line with the label CPU Temperature or something similar, along with the current temperature in degrees Celsius.

For example, the output might look something like this:

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +51.0°C  (high = +80.0°C, crit = +100.0°C)
Core 0:        +50.0°C  (high = +80.0°C, crit = +100.0°C)
Core 1:        +50.0°C  (high = +80.0°C, crit = +100.0°C)

In this example, the CPU temperature is listed as +50.0°C.

It's worth noting that the sensors command relies on the lm-sensors package, which may not be installed by default on all systems.
