DESCRIPTION
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
