Running extundelete version 0.0.3
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.
Actions:
  --inode ino            Show info on inode 'ino'.
  --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, inode.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 directory, file or symbolic link is
                         created in the current directory as ./'path'.
