dmidecode 명령으로 하드웨어 정보 확인하기

컴퓨터의 DMI(Desktop Management Interface)를 사람이 읽을 수 있게 dumping 하는 명령
시스템 정보를 자세하게 출력해 주기 때문에 유용한 명령어 이다.

 

사용법

아무런 옵션 없이 dmidecode 명령을 입력하면, 모든 정보가 한꺼번에 지나가 버리기 때문에, 아래와 같이

more 를 사용해서 확인을 하거나, -t, -s 등의 옵션을 사용해서 확인 하면 된다.

=====================================================

[root@localhost ~]# dmidecode | more
