    extundelete - 实用程序从EXT3 / EXT4分区恢复删除的文件
    :~# extundelete --help
    Usage: extundelete [options] [--] device-file
    --version, -[vV]       Print version and exit successfully.
    --help,                Print this help and exit successfully.
    --superblock           Print contents of superblock in addition to the rest.
                           If no action is specified then this option is implied.
    --journal              Show content of journal.
    --after dtime          Only process entries deleted on or after 'dtime'.
    --before dtime         Only process entries deleted before 'dtime'.
    --inode ino            Show info on inode 'ino'.
    --block blk            Show info on block 'blk'.
    --restore-inode ino[,ino,...]
                           Restore the file(s) with known inode number 'ino'.
                           The restored files are created in ./RESTORED_FILES
                           with their inode number as extension (ie, file.12345).
    --restore-file 'path'  Will restore file 'path'. 'path' is relative to root
                           of the partition and does not start with a '/' (it
                           must be one of the paths returned by --dump-names).
                           The restored file is created in the current
                           directory as 'RECOVERED_FILES/path'.
    --restore-files 'path' Will restore files which are listed in the file 'path'.
                           Each filename should be in the same format as an option
                           to --restore-file, and there should be one per line.
    --output-dir 'path'    Restore files in the output dir 'path'.
                           By default the restored files are created under current directory 'RECOVERED_FILES'.
    --restore-all          Attempts to restore everything.
    -j journal             Reads an external journal from the named file.
    -b blocknumber         Uses the backup superblock at blocknumber when opening
                           the file system.
    -B blocksize           Uses blocksize as the block size when opening the file
                           system.  The number should be the number of bytes.

    读取分区 (为/ dev / sda1的)和恢复 ( -还原文件) 指定的文件名 ​​(根/ importantfile):
:~# extundelete /dev/sda1 --restore-file root/importantfile
WARNING: Extended attributes are not restored.
The partition should be unmounted to undelete any files without further data loss.
If the partition is not currently mounted, this message indicates 
it was improperly unmounted, and you should run fsck before continuing.
If you decide to continue, extundelete may overwrite some of the deleted
files and make recovering those files impossible.  You should unmount the
file system and check it with fsck before using extundelete.
