[root@localhost ~]# rpm -qa | grep redhat-release

有的版本返回如下信息
[root@q1test01 ~]# rpm -q redhat-release
redhat-release-4AS-3
注: 这种方式下可看到一个所谓的release号，上边的例子是3
这个release号和实际的版本之间存在一定的对应关系，如下：
redhat-release-3AS-1 -> Redhat Enterprise Linux AS 3
redhat-release-3AS-7.4 -> Redhat Enterprise Linux AS 3 Update 4
redhat-release-4AS-2 -> Redhat Enterprise Linux AS 4
redhat-release-4AS-2.4 -> Redhat Enterprise Linux AS 4 Update 1
redhat-release-4AS-3 -> Redhat Enterprise Linux AS 4 Update 2
redhat-release-4AS-4.1 -> Redhat Enterprise Linux AS 4 Update 3
redhat-release-4AS-5.5 -> Redhat Enterprise Linux AS 4 Update 4
说明：第3)、4)两种方法只对Redhat Linux有效
