寫一個(gè)腳本（前提：請(qǐng)為虛擬機(jī)新增一塊硬盤，假設(shè)它為/dev/sdb）,為指定的硬盤創(chuàng)建分區(qū)

1，列出當(dāng)前系統(tǒng)上所有的磁盤，讓用戶選擇，如果選擇quit則退出腳本；如果用戶選擇錯(cuò)誤，就讓用戶重新選擇

2，檔用戶選擇后，提醒用戶確認(rèn)接下來的操作可能會(huì)損壞數(shù)據(jù)，并請(qǐng)用戶確認(rèn)：如果用戶選擇y就繼續(xù)，n就退出；否則，讓用戶重新選擇；

3，抹除那塊硬盤上的所有分區(qū)(提示，抹除所有分區(qū)后執(zhí)行sync命令，并讓腳本睡眠3秒后在分區(qū))，并為其創(chuàng)建三個(gè)主分區(qū)，第一個(gè)為20M，第二個(gè)為512M，第三個(gè)為128M，切第三個(gè)為swap分區(qū)類型；(提示：將分區(qū)命令通過echo傳給fdisk即可實(shí)現(xiàn))
