shell实现多级菜单脚本编写

P安装展现效果,需要的朋友可以参考下：

提示：本脚本主要实现多级菜单效果，并没有安装LAMP、LNMP环境，如果要用在实际生成环境中部署LNMP、LAMP环境，只需要简单修改一下就可以了。

演示效果：

1、一级菜单

(转)shell实现多级菜单脚本编写_linux

2、二级菜单

(转)shell实现多级菜单脚本编写_shell_02

3、执行操作

(转)shell实现多级菜单脚本编写_php_03

脚本参考：

代码如下：

#!/bin/bash
#
[ -f /etc/init.d/functions ] && . /etc/init.d/functions
function menu(){
cat << EOF
----------------------------------------------
|*******Please Enter Your Choice:[1-4]*******|

}
