Recover files that were mistakenly deleted in Linux

Use the Delete command with caution!

Recovery is because your sector is not covered, this is why copy files so slow and delete files so fast, because the deletion is only the filename, the inode number is still good.

The downloaded EXTUNDELETE-0.2.4.TAR.BZ2 software must first be uploaded to the Linux system and extracted

TAR-JXVF extundelete-0.2.4.tar.bz2

Uninstall the partitions that need to be recovered

Umount/tmp/sdb1

CD to extundelete-0.2.4 directory

Perform source code compilation./configure, usually error, so use RPM to install a bag called e2fsprogs-devel*

Then execute./configure #检查安装环境并生成makefile文件

Execute the Make command #编译 (three axes:./configure, make, make install)

Execute the Make install command #安装

Recovery Method 1: View the deleted file name through the Inode node

Create a directory as a recovery point

EXTUNDELETE/TMP/SDA1--inode 2 #可看到inode号和delete被删除状态

EXTUNDELETE/TMP/SDA1--restore-inode #12是查看到的想恢复文件的节点数

Method 2: Restore by file name

EXTUNDELETE/TMP/SDA1--restore-file a.txt #a. txt is the name of the file you want to recover (similarly, if you want to restore the directory, change file to directory)

EXTUNDELETE/TMP/SDA1--restore-all #一次性恢复全部被删除的文件!
