Music Duplicate Finder Command Line for Mac

Are you struggling with a cluttered music library on your Mac? A music duplicate finder command line tool can help you identify duplicate tracks quickly, especially across large folders.

Using a command line interface allows for greater control and flexibility when scanning your music files. A common approach is to compute a checksum for each file (macOS includes the md5 command) and look for matching values, which finds exact copies even when the names differ. Open-source duplicate finders that run in Terminal do the same across whole folders. These tools catch only byte-for-byte copies, and deleting a file your DJ software uses breaks its library entry, so review the list and back up before you delete.

Dupes is not a command line tool. It is a Mac app for DJs on Serato DJ Pro: Dupes reads your Serato library directly, finds duplicates by comparing track metadata, and updates your Serato crates when it removes a copy. If that is your setup, it saves you the scripting.
