       ext3grep - ext3 file recovery tool


       ext3grep [OPTIONS] FILE ...


       ext3grep  is  a  simple  tool intended to aid anyone who accidentally deletes a file on an
       ext3 filesystem, only to find that they wanted it shortly thereafter.


           Print contents of superblock in addition to the rest. If no action is  specified  then
           this option is implied.

           Print contents of block or inode, if any.

           Print  directories,  one  line  per  entry.  See  the  FILTERS  section for details on
           filtering this output.

       --accept FILE
           Accepts 'file' as a legal filename. Can be used multiple  times.  If  you  change  any
           --accept you must remove BOTH stage* files!

           Prints the contents of the journal.

           Show the inode of each directory component in paths.

       --group gid
           Only show/process files owned by process group gid.

           Only show/process process directory inodes.

       --after dtime
           Only show/process entries deleted on or after dtime.

       --before dtime
           Only show/process entries deleted before dtime.

           Only show/process deleted entries.

           Only show/process allocated inodes/blocks.

           Only show/process unallocated inodes/blocks.

           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.

           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'.

       --inode-to-block inode_num
           Print the block that contains inode inode_num.

       --inode inode_num
           Show info on inode inode_num. 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

       --block block_num
           Show info on block block_num. 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.

           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 block_num
           Show info on journal block block_num.

       --journal-transaction seq
           Show info on transaction with sequence number seq.

           Write the paths of files to stdout. This implies --ls but suppresses its 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 block_num
           Find inodes that refer to block block_num.

           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 inode_num
           Show copies of inode inode_num still in the journal.

       --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.

           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 all inodes that are shared by two or more files.

       --version, -[vV]
           Prints the version information and exits.

           Prints a help message and exits.


       Restoring all files from the ext3 partition/file /backup/sda1:
       ext3grep --restore-all /backup/sda1
       Listing the files owned by GID 1000 on /backup/sda1:
       ext3grep --ls --group 1000 /backup/sda1
       Finding all files containing the string Critical_report in their name on /backup/sda1:
       ext3grep --dump-names /backup/sda1 | grep 'Critical_report'


       Do not attempt to use ext3grep for recovery from a mounted filesystem. Ever.

       No, not even then.

       ext3grep sometimes runs out of memory spare on 32-bit architectures  and  crashes.  It  is
       highly  recommended  that you run ext3grep in a 64-bit environment when dealing with large
       filesystems, though this is seen as a bug.

       ext3grep cannot recover files if there are no remnants of them.

       Some files that ext3grep recovers may have trailing null bytes - just scrape them off like
       the burnt bits on toast.
