Ever stuck in a situation where you accidentally deleted a file? In this tutorial, we’ll go over how to install TestDisk in Linux and recover deleted files.
是否曾经遇到过意外删除文件的情况？ 在本教程中，我们将介绍如何在Linux中安装TestDisk以及恢复已删除的文件。
In this tutorial, I’ll be using an Ubuntu server to work with, but even if you are on any other distribution, you can follow the same steps. The only thing that will be different is the package manager used for installation.
在本教程中，我将使用Ubuntu服务器进行工作，但是即使您使用任何其他发行版，也可以按照相同的步骤进行操作。 唯一不同的是用于安装的程序包管理器。
在Linux上安装TestDisk (Install TestDisk on Linux )
Thetestdiskpackage is available on all the major Linux distributions and can be easily downloaded with the use of the default package manager. Here, I’ve listed down the distro-specific commands to install testdisk on Linux.
testdisk软件包在所有主要的Linux发行版中都可用，并且可以使用默认的软件包管理器轻松下载。 在这里，我列出了在Linux上安装testdisk的特定于发行版的命令。

您可能不需要检查分区类型，因为上面的列表涵盖了几乎所有主要分区类型。 但是，如果不确定，请输入以下命令之一：
stat -f <partition>df -Tfdisk -l
Either of the commands above will give you the filesystem type information.
上面的任何一个命令都会为您提供文件系统类型信息。
1.启动TestDisk并配置其运行位置 (1. Starting TestDisk and Configuring Where it Runs)
In your terminal, simply enter the commandtestdiskto run the utility and you’ll be greeted with the below prompt. You can select the appropriate disk drive that you want to recover files on.
在您的终端中，只需输入命令testdisk即可运行该实用程序，然后会出现以下提示。 您可以选择要在其上恢复文件的适当磁盘驱动器。
If its the first time you’re running this utility, it will give you an option to create a log file on the welcome screen. You can select create and just move ahead with the defaults.
如果是第一次运行此实用程序，它将为您提供一个在欢迎屏幕上创建日志文件的选项。 您可以选择创建，然后继续使用默认设置。

2.选择和分析分区 (2. Selecting and Analyzing the Partition)
Once you’ve selected the right partition, you will be asked to select the partition type.
选择正确的分区后，将要求您选择分区类型。
It should auto-select the correct partition type, but if it doesn’t, make sure you select the correct type.
它应该自动选择正确的分区类型，但是如果没有，请确保选择正确的类型。
Once that’s done, you’ll be given a menu of options out of which we need to go ahead with “Analyse” to search for lost data.

You can go with “Quick Search” or “Deeper Search” as it fits your needs and let the search run until it has scanned all the inodes.
您可以根据需要选择“快速搜索”或“深度搜索”，然后运行搜索直到扫描完所有inode。
3.扫描分区中已删除的文件 (3. Scanning the Partition for Deleted Files)
With the option selected, you’ll be greeted with which specific partition you want to scan.

Select the correct partition, and let the utility scan the entire drive. Within some time, you’ll get the list of files within the partition. When the scanning is in progress, you’ll see a screen similar to the one below.
选择正确的分区，然后让实用程序扫描整个驱动器。 在一段时间内，您将获得分区内文件的列表。 进行扫描时，您会看到类似以下的屏幕。
Now once the progress is completed, it provides you with the option to select the partition that you want to browse the files in. All the files that are highlighted in “red” or any color or text style (can also be influenced by terminal configuration) are the files that have been recovered by the TestDisk utility.
现在，完成进度后，它为您提供了选择要浏览文件的分区的选项。所有以“红色”或任何颜色或文本样式突出显示的文件（也可能会受到终端配置的影响） ）是TestDisk实用程序已恢复的文件。
