NAME
       extundelete - utility to undelete files from an ext3 or ext4 partition.

SYNOPSIS
       extundelete [options] device-file...

DESCRIPTION
       extundelete is a utility that can recover deleted files from an ext3 or ext4 partition
       extundelete uses the information stored in the partition's journal to attempt to recover a file that has been deleted from the partition.
       There  is  no  guarantee  that any particular file will be able to be undeleted, so always try to have a good backup system in place, or at
       least put one in place after recovering your files!

OPTIONS
       --version
	      Prints the version number of extundelete.

       --help Print a brief usage summary for extundelete.

       Partition name
	      Name of the partition that has deleted files, such as /dev/sda3.
	      Could also be the file name of a copy of the partition, such as that made with dd.

       --superblock
	      Prints information about the filesystem from the superblock.

       --journal --superblock
	      Prints information about the journal from the journal's superblock.

       --inode #
	      Prints the information from the inode number of the filesystem given, such as "--inode 2".

       --block #
	      Prints the contents of the block, called as "--block 9652".

       --restore-file path/to/deleted/file
	      Attempts to restore the file which was deleted at the given filename, called as "--restore-file dirname/filename".

       --restore-inode #
	      Used to restore inodes by number, called as "--restore-inode 2569".
	      Also accepts a list of inodes separated by only commas, such as "--restore-inode 2569,5692,6925".

       --restore-files filename
	      Restores a list of files. First, construct a list of files in the same style as would be
	      used in the --restore-file option, and save it to the file "filename".
	      Then, this option may be used to attempt to restore those files with a single call to extundelete.
	      This form also reduces redundancy from multiple calls parsing the journal multiple times.

       --output-dir path/to/dump/recovered/files
	      Restores files in the output dir 'path'.
	      By default the restored files are created under current directory 'RECOVERED_FILES'

       --restore-all
	      Restores all files possible to undelete to their names before deletion, when possible.  Other files are restored to a filename  like
	      "file.NNNN".

       --restore-directory path/of/directory
	      Restores all files possible to link to specified directory to their names before deletion, when possible.

       -j journal_dev
	      Specifies the device that is the external journal of the file system.

       -b block_number
	      Specifies the block number of the backup superblock to be used when opening the file system.

       -B block_size
	      Specifies the block size of the partition to be used when opening the file system.

       --before date
	      Only  restore  files  deleted  before the date specified, which should be in the form of the number of seconds since the UNIX epoch.
	      Use a shell command like
	      $ date -d "Aug 1 9:02" +%s
	      to convert a human-readable date to the proper format. The conversion from the number of seconds to a readable format may  be  found
	      by using either of the following:
	      $ date -d@1234567890
	      $ perl -le "print scalar localtime 1234567890"

       --after date
	      Only restore files deleted after the date specified, which should be in the form of the number of seconds since the UNIX epoch.
	      See the notes for the --before option for more information.
