fdupes is a linux utility that uses md5sums to find duplicate files within a set of directories, using byte by byte comparison. Some of it’s options includes following sysmlinks and hardlinks, using recursive directory search, show file size in bytes and prompt user for file deletion.

We can start up fdupes with this simple command fdupes -r -S -d /home/pavs , here I am asking fdupes to do recursive file search and show me the size of the file and finally prompt me for file deletion.
