리눅스 OS 버전, bit 확인하기 (OS & version, cpu, bit check)

현재 접속한 리눅스 서버에 대한 OS, 버전 정보를 확인하고자 하는 경우가 있죠?

이런 경우에 아래의 명령들중에서 적당한 것을 사용하시면 되겠습니다.

※ 일반적으로 자주 사용하는 명령

[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost ~]# 
[root@localhost ~]# uname --help
Usage: uname [OPTION]...
Print certain system information.  With no OPTION, same as -s.
 
  -a, --all                print all information, in the following order,
                             except omit -p and -i if unknown:
  -s, --kernel-name        print the kernel name
  -n, --nodename           print the network node hostname
  -r, --kernel-release     print the kernel release
  -v, --kernel-version     print the kernel version
  -m, --machine            print the machine hardware name
  -p, --processor          print the processor type or "unknown"
  -i, --hardware-platform  print the hardware platform or "unknown"
  -o, --operating-system   print the operating system
      --help     이 도움말을 표시하고 끝냅니다
      --version  버전 정보를 출력하고 끝냅니다
