finddup search the working directory and all files below on the same partition for duplicate files.

       finddup can optional hardlink such files to save space.

       Files size 0 will not be reported or hardlinked as this might give problemes later.

       This is a complete rewrite of the finddup in perl to handle several issues:

         - Allow spaces and other characters in filenames

         - be faster

         - include nodup in same script

         - Handle files that already have other hardlinks in the same tree

         - Several improvements

       If started as nodup or nodup.pl the script will act like started with options --link and --oldresult

       $Log: finddup,v $ Revision 2.3  2005/02/06 18:57:42  klaus * Make --oldresult faster by  not  calculating
       the md5sum again * Fix a but that with --oldresult no links will be done cause the internal
         datastructure * Do handle errors in open for md5sum calculation

       Revision 2.2  2005/02/06 12:21:02  klaus Little but important bug in link routine.
