以下是指令碼內容，內容比較簡單，不做詳解

在Linux上準備一塊閒置磁碟即可，如何分區可以在指令碼內改下

#!/bin/bash

echo "Initial a disk..."

echo -e "\033[31mWarning: \033[0m "

#開始的說明資訊，其中Warning以紅色字型顯示

fdisk -l 2> /dev/null | grep -o "^Disk /dev/[sh]d[a-z]"

#顯示所有磁碟裝置

read -p "Your choice(Disk or quit):" PARTDISK

if [ $PARTDISK == ‘quit‘ ]; then

  echo "quit"

  exit 7

fi

for I in `mount | grep "$PARTDISK" | awk ‘{print $1}‘`;do

  fuser -km  $I

  umount $I

  echo "$I umount ok."

done
