解決：-bash: lsb_release: command not found辦法

lsb_release能夠查看系統工具，可是不少系統都沒裝這個命令。其實我也不建議用
lsb_release 來查看系統版本，由於有更好的方法。之因此我不推薦，是有緣由的，見下
面解決：-bash: lsb_release: command not found辦法：

-bash: lsb_release: command not found 就是 lsb_release命令沒有安裝。因此咱們用
yum命令安裝下就好了。

先看看這個命令屬於哪一個軟件包：

# yum provides */lsb_release

[root@ksharpdabu ~]#  yum provides */lsb_release

能夠看出，屬於redhat-lsb這個包，那麼接着使用yum安裝這個包：

# yum install  -y  redhat-lsb

截取一部分運行結果

能夠看到，爲了裝個lsb_release ，就還要裝104M的其餘依賴包之類的。這就是我不推薦這個命令查系統的緣由。

而後，就能夠使用lsb_release 查看系統版本了;
# lsb_release  -r

Release:    6.5

其餘用法，可本身使用 「-h」 自行查閱。
