리눅스 버전 및 CPU 등 환경정보를 확인하기 위한 명령어 모음

리눅스 버전및 CPU등 환경정보 확인하기 위한 명령어 입니다.

 

* 리눅스 버전 확인

# cat /etc/issue

CentOS release 5.4 (Final)
Kernel \r on an \m

또는

# cat /etc/redhat-release

Linux version 2.6.18-164.6.1.el5 (mockbuild@builder16.centos.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-46)) #1 SMP Tue Nov 3 16:18:27 EST 2009

 

* OS 커널 비트수(Kernel Bits)  확인하기

# getconf WORD_BIT

32

 

* uname 명령(unix name의 줄임말) 으로 OS Kernel Architecture  확인하기

 # uname -m

i686

 

 

<참고 : uname 명령어 사용법>

# uname (옵션)
>> 옵션
