It requires that the unix find and md5sum commands are on your system. ; Installation: Put dired-dups.el in a directory in your load-path, e.g. ~/.emacs.d/ You can add a directory to your load-path with the following line in ~/.emacs (add-to-list 'load-path (expand-file-name "~/elisp")) where ~/elisp is the directory you want to add (you don't need to do this for ~/.emacs.d - it's added by default). Add the following to your ~/.emacs startup file. (require 'dired-dups)
