在Redhat，CentOS和Fedora Linux中从意外删除的文件或崩溃的驱动器进行数据恢复
版本2.0
作者：Srijan Kishore
本教程将帮助您从Linux文件系统中从意外删除的数据中恢复数据。 任何用户/管理员都是非常严重的错误，造成巨大的惩罚。 这个脚本将是新手/专家数据管理的福音。 我将使用TestDisk进行数据恢复。 在这里我用脚本帮助简化了这个任务。
背景
TestDisk是一款功能强大的免费数据恢复软件。 假设你有一个ext3 / ext4驱动器，它使用
rm -rf或shift + delete like命令进行崩溃/删除，借助于TestDisk，您可以恢复数据/文件。
TestDisk可以用于
要求
我正在使用CentOS，我将在其上安装TestDisk，并在崩溃的驱动器上实现数据恢复脚本。 这个脚本与CentOS / Fedora / Redhat一起工作正常。 即使发生任何硬盘被删除，只需将硬盘连接到CentOS机器并运行脚本来恢复数据。
TestDisk可以用于
- 修复分区表
- 从FAT，exFAT，NTFS和ext2 / ext3 / ext4分区中取消删除文件
除了这些功能，TesdDisk还具有数据维护/管理功能

4.脚本执行
只需复制上述脚本并粘贴到文件中即可。 script.sh并给脚本执行执行权限。
chmod + x script.sh
注意：请使用该命令用root运行该脚本
su - #### Put your root password##########
运行脚本，它将引导你进一步。
sh script.sh
5.定稿
首先脚本将确认运行该脚本的用户是否为根，然后它将检查包含自动存储库添加的TestDisk工具安装。 它将重定向到驱动器选择页面进行数据恢复。
它将检查您的操作系统。
脚本将自动验证并添加TestDisk所需的存储库。
脚本将检查TestDisk的安装。
选择要恢复的驱动器。
处理完成后，退出屏幕。
干杯你已经恢复了你的数据。
