如何查看Linux操作系统版本？
1. 查看内核版本命令：
$ cat /proc/version Linux version 2.6.32-358.el6.x86_64 ([email protected]) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Fri Feb 22 00:31:26 UTC 2013 $ uname -a Linux 192.168.1.10 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux $ uname -r 2.6.32-358.el6.x86_64
2. 查看Linux版本：
1) 执行 lsb_release -a ,即可列出所有版本信息,例如:
$ lsb_release -a LSB Version: core-2.0-noarch:core-3.0-noarch:core-2.0-ia32:core-3.0-ia32:graphics-2.0-ia32:graphics-2.0-noarch:graphics-3.0-ia32:graphics-3.0-noarch Distributor ID: SUSE LINUX Description: SUSE LINUX Enterprise Server 9 (i586) Release: 9 Codename: n/a
注:这个命令适用于所有的linux，包括Redhat、SuSE、Debian等发行版。
2) 执行cat /etc/issue,例如如下:
$ cat /etc/issue Welcome to SUSE LINUX Enterprise Server 9 (i586) - Kernel \\r (\\l).
3) 执行cat /etc/redhat-release ,例如如下:
$ cat /etc/*release* CentOS release 6.4 (Final) CentOS release 6.4 (Final) CentOS release 6.4 (Final) cpe:/o:centos:linux:6:GA
