finddup [options...]

-h, --help

-v, --verbose
just what the name says
-q, --quiet

-l, --link

-o, --oldresult

-i, --ignore-perms
Don't check that file owner and permissions match
-d, --dir
Define the dir to check (you may specify more than one)


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 the script will act like started with options --link and --oldresult
