버전 확인 기본 명령어

1.OS 버전 확인

명령어 : cat /etc/redhat-release or cat /etc/issue 

 

$ cat /etc/redhat-release

CentOS release 6.3 (Final)

 

 

2. 리눅스 커널 버전 확인

명령어 : cat /proc/version

 

$ cat /proc/version

Linux version 2.6.32-279.11.1.el6.x86_64 (mockbuild@c6b9.bsys.dev.centos.org) (gcc version 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC) ) #1 SMP Tue Oct 16 15:57:10 UTC 2012

 

 

3. OS 커널 비트수 확인 

명령어:

Solaris : isainfo -kv

HP-UX : getconf KERNEL_BITS

AIX : bootinfo -k

Linux : getconf WORD_BIT  

Linux (64bit 확인) : getconf LONG_BIT

 

$ getconf WORD_BIT

32

$ getconf LONG_BIT

64

 

 

4. OS Kernel Architecture 확인

명령어 : uname -m

# uname (옵션)

-a : All 모든 정보

-i : Platform 정보

-m : System Kernel Architecture 정보

-n : Nodename(Host name) 정보

-p : Processor(Processor type) 정보

-r : System OS Release 정보

-s : System OS 정보

-v : Kernel ID 정보

-X : 조금더 디테일 한 정보

-S : 호스트 이름 변경

 

$ uname -m

x86_64
