简介

一说到命令行，我们真正指的是 shell。shell 就是一个程序，它接受从键盘输入的命令， 然后把命令传递给操作系统去执行。几乎所有的 Linux 发行版都提供一个名为 bash 的 来自 GNU 项目的 shell 程序。bash 是 Bourne Again SHell 的首字母缩写， 所指的是这样一个事实，bash 是最初 Unix 上由 Steve Bourne 写成 shell 程序 sh 的增强版。

编写 shell 脚本

将下面你的 shell 脚本保存在 .sh 的文件中。放在本地虚拟机上直接运行就行了。
前提虚拟机必须是CentOS7， 并且能连上外网。

#!/bin/sh

release_file='/etc/redhat-release'
if [ -f $release_file ];then
    echo $release_file
else
    echo 'no file redhat-release'
    exit
fi

release=`cat $release_file | awk '{print $4}'`
if [ ${release:0:1} != '7' ];then
    echo 'only support centos7'
    exit
fi

泡杯咖啡，坐等安装完毕就行了。
