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.

   --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.
