root@kali:~# ext3grep --help
Running ext3grep version 0.10.2
Usage: ext3grep [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.
  --print                Print content of block or inode, if any.
  --ls                   Print directories with only one line per entry.
                         This option is often needed to turn on filtering.
  --accept filen         Accept 'filen' as a legal filename. Can be used multi-
                         ple times. If you change any --accept you must remove
                         BOTH stage* files!
  --accept-all           Simply accept everything as filename.
  --journal              Show content of journal.
  --show-path-inodes     Show the inode of each directory component in paths.
Filters:
  --group grp            Only process group 'grp'.
  --directory            Only process directory inodes.
  --after dtime          Only entries deleted on or after 'dtime'.
  --before dtime         Only entries deleted before 'dtime'.
  --deleted              Only show/process deleted entries.
  --allocated            Only show/process allocated inodes/blocks.
  --unallocated          Only show/process unallocated inodes/blocks.
  --reallocated          Do not suppress entries with reallocated inodes.
                         Inodes are considered 'reallocated' if the entry
                         is deleted but the inode is allocated, but also when
                         the file type in the dir entry and the inode are
                         different.
  --zeroed-inodes        Do not suppress entries with zeroed inodes. Linked
                         entries are always shown, regardless of this option.
  --depth depth          Process directories recursively up till a depth
                         of 'depth'.
Actions:
  --inode-to-block ino   Print the block that contains inode 'ino'.
  --inode ino            Show info on inode 'ino'.
                         If --ls is used and the inode is a directory, then
                         the filters apply to the entries of the directory.
                         If you do not use --ls then --print is implied.
  --block blk            Show info on block 'blk'.
                         If --ls is used and the block is the first block
                         of a directory, then the filters apply to entries
                         of the directory.
                         If you do not use --ls then --print is implied.
  --histogram=[atime|ctime|mtime|dtime|group]
                         Generate a histogram based on the given specs.
                         Using atime, ctime or mtime will change the
                         meaning of --after and --before to those times.
  --journal-block jblk   Show info on journal block 'jblk'.
  --journal-transaction seq
                         Show info on transaction with sequence number 'seq'.
  --dump-names           Write the path of files to stdout.
                         This implies --ls but suppresses it's output.
  --search-start str     Find blocks that start with the fixed string 'str'.
  --search str           Find blocks that contain the fixed string 'str'.
  --search-inode blk     Find inodes that refer to block 'blk'.
  --search-zeroed-inodes Return allocated inode table entries that are zeroed.
  --inode-dirblock-table dir
                         Print a table for directory path 'dir' of directory
                         block numbers found and the inodes used for each file.
  --show-journal-inodes ino
                         Show copies of inode 'ino' still in the journal.
  --restore-inode ino[@seqnr][,ino[@seqnr],...]
                         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).
                         If '@seqnr' is provided then (only) the journal entry
                         with that sequence number is used, otherwise the latest
                         entry is used (if any). You can use that in the case a
                         a file was overwritten or truncated, rather than deleted.
  --restore-file 'path' [--restore-file 'path' ...]
                         Will restore file 'path'. 'path' is relative to the
                         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 'RESTORED_FILES/path'.
  --restore-all          As --restore-file but attempts to restore everything.
                         The use of --after is highly recommended because the
                         attempt to restore very old files will only result in
                         them being hard linked to a more recently deleted file
                         and as such pollute the output.
  --show-hardlinks       Show all inodes that are shared by two or more files.
