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.
