lsb_release可以查看系统工具，但是很多系统都没装这个命令。其实我也不建议用
lsb_release 来查看系统版本，因为有更好的方法。之所以我不推荐，是有原因的，见下
面解决：-bash: lsb_release: command not found办法：
-bash: lsb_release: command not found 就是 lsb_release命令没有安装。所以我们用
yum命令安装下就行了。
先看看这个命令属于哪个软件包：
# yum provides */lsb_release</p> <p>[root@ksharpdabu ~]# yum provides */lsb_release

可以看出，属于redhat-lsb这个包，那么接着使用yum安装这个包：
# yum install -y redhat-lsb
截取一部分运行结果

可以看到，为了装个lsb_release ，就还要装104M的其他依赖包之类的。这就是我不推荐这个命令查系统的原因。
然后，就可以使用lsb_release 查看系统版本了;
# lsb_release -r</p> <p>Release: 6.5
其他用法，可自己使用 “-h” 自行查阅。
