    28 freedups.

    29 ---------

    30 

    31 Freedups searches through the directories you specify. When it finds two

    32 identical files, it hard links them together. Now the two or more files still

    33 exist in their respective directories, but only one copy of the data is stored

    34 on disk; both directory entries point to the same data blocks.

    39 dupmerge.

    40 ---------

    41 

    42 Dupmerge reads a list of files from standard input (eg., as produced by "find .

    43 -print") and looks for identical files. When it finds two or more identical

    44 files, all but one are unlinked to reclaim the disk space and recreated as hard

    45 links to the remaining copy.

    52 ssdeep.

    53 -------

    54 

    55 ssdeep is a program for computing context triggered piecewise hashes (CTPH).

    56 Also called fuzzy hashes, CTPH can match inputs that have homologies. Such

    57 inputs have sequences of identical bytes in the same order, although bytes in

    58 between these sequences may be different in both content and length.
