Packages and Binaries:
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.
This package is useful in forensics investigations.
How to install:
sudo apt install ext3grep
Ext3 file recovery tool
[email protected]:~# 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.
