#!/bin/bash
#写一个脚本(前提：请为虚拟机新增一块硬盘，假设它为/dev/sdb)，为指定的硬盘创建分区：
#1、列出当前系统上所有的磁盘，让用户选择，如果选择quit则退出脚本；如果用户选择错误，就让用户重新选择；
#2、当用户选择后，提醒用户确认接下来的操作可能会损坏数据，并请用户确认；如果用户选择y就继续，n就退出；否则，让用户重新选择；
#3、判断当前磁盘是否挂载使用，如使用，先卸载；
#4、抹除那块硬盘上的所有分区(提示，抹除所有分区后执行sync命令，并让脚本睡眠3秒钟后再分区)；并为其创建三个主分区，第一个为20M，第二个为512M, 第三个为128M，且第三个为swap分区类型；(提示：将分区命令通过echo传送给fdisk即可实现)
