$ extundelete --help

Usage: extundelete [options] [--] device-file

Options:

  --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‘.

Actions:

  --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.

  --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.
