查看linux版本信息
- uname -a
- cat /proc/version

- Red Hat Enterprise Linux AS release 4 (Nahant Update 1)

这种方式下可看到一个所谓的release号,比如上边的例子是2.4- [[email protected] ~]# rpm -q redhat-release

注意:第2、3两种方法只对Redhat Linux有效- 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
