解决：-bash: lsb_release: command not found办法

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

[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

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

Release:    6.5

其他用法，可自己使用 “-h” 自行查阅。
