DeDup

NAME
       dedup - search for files with the same content

SYNOPSIS
       dedup [option] dirs...


DESCRIPTION
       Utility for finding files with the same content and creating hard links
       to the first copy

       The utility is written to find duplicates in the archive of photos  and
       videos.   If  when  reading the next file the hash sum and size are the
       same as the previous one, it is considered  a  duplicate.   File  time‐
       stamps are not taken into account.

       To  reduce  the  search time in a large archive you can specify to read
       only the first N bytes, usually different video  files  have  different
       checksums  already within the first 1Mb.  If the file sizes are differ‐
       ent, the file will also not be considered a duplicate.

       By default, only the listing is created.

       Existing hard link is not counted because it may lead outside the  tree
       it is analyzing.
