[Ubuntu] 우분투 18.04 에서 CPU 온도 확인하기

우분투 18.04 CPU 온도 확인하기

리눅스 CPU 온도 확인하는 방법

lm-sensors 설치하기

우분투 18.04 에서 apt 명령어로 lm-sensors 를 설치한다.

$ sudo apt install lm-sensors

환경설정을 위해 sensor-detect 를 설치하고 온도를 확인하는 센서에 yes 를 입력한다.

$ sudo sensors-detect

lm-sensors 실행하기

sensors 명령어로 각 부품의 상태와 온도를 확인할 수 있다.
