• 방법2 
• 배포판의 버전을 가장 쉽게 확인하는 방법
• 보안 등의 이유로 다른 내용으로 바뀌어 있는 경우도 있음 (아래처럼)

[root@tez ~]# grep . /etc/issue*

/etc/issue:\S

/etc/issue:Kernel \r on an \m

/etc/issue.net:\S

/etc/issue.net:Kernel \r on an \m

• 방법3 : rpm 계열에서 사용
  

[root@tez ~]# rpm -qa *-release

centos-release-7-2.1511.el7.centos.2.10.x86_64
