File Mgmt. Removing duplicate files.
 

I apologize in advance if this is posted elsewhere in the forums. I have a mess of music on my external that I would like to clean up. I'm wondering if there is any programs or commands out there that will allow me to search a directory, and all sub-directories, for duplicate files. Further, is there a way to show files that are duplicates but have case changes in the name (i.e. song, Song)? I've been digging through the internets but just can't seem to find what I'm looking for. Also, is there any way you can tell if a file is a duplicate even if it has a different name without having to open it? I'm running Mint 12, 64-bit. Thank you!

To list duplicates:

To delete duplicates automatically:

You can use the find command to search a file recursively in a directory. Here is an example that I use many times to find files.

#find <path> -type f -iname <filename>

May be you can also write a script and process the output from find to achieve how you want to manage the duplicacy of files.

This solution does not satisfy OP's request to not be dependent on filenames:

fdupes compares files by sizes and MD5 signatures, followed by a byte-by-byte comparison - so filenames can be completely different.
