How to Find File Duplicates for Free Using Mac Terminal

If you’re willing to use the Terminal app, you can find duplicate files using a well-known code that turns out to be a built-in Mac duplicate file finder. This method will work on one folder at a time, so consider the tools we featured in the last section if you prefer bulk deletion.

This method has been tested on machine running macOS Sonoma. But the steps for the macOS Monterey and macOS Ventura are similar.

To use the Terminal app to find duplicates:

  1. Open the Terminal app (Finder > Applications).
    Terminal app icon in Finder
  2. Type the following command and hit Return:
    cd desktop

    Replace “desktop” with the location you want to scan.
    CD command execution in the Terminal app

  3. Copy and paste the following command in Terminal and hit Return:
    find ./ -type f -exec md5 {} \; | awk -F '=' '{print $2 "\t" $1}' | sort | tee duplicates.txt

    Find Duplicates command in the Terminal app in Finder

  4. In the location you defined in step 2, you’ll find a TXT file called duplicates.txt, which contains a list of the duplicates it found in said location.
    Txt file of found duplicate files


There are a few possibilities why your Mac is duplicating files:

  • Backup software is saving multiple versions of the same files.
  • You copied a file to an external drive and forgot to delete it on your Mac.
  • You enabled Live Photos on your iPhone (or similar tools).
  • Malware or faulty software is causing this behavior.

There are free third-party duplicate file finders and paid software that offers free trials. If you don’t want to use a third-party software, you can use the following commands in Terminal:

cd ~/desktop

Replace “desktop” with the folder you want to check for duplicates. Then, type the following command and hit the return key to generate a TXT file with a list of duplicates in the folder you specified in the last command:

find ./ -type f -exec md5 {} ; | awk -F '=' '{print $2 "t" $1}' | sort | tee duplicates.txt

To delete duplicate files on Mac, you can either (1) use a third-party duplicate file finder or (2) use the following Terminal commands:

cd ~/desktop

Make sure to replace “desktop” with the location you want Terminal to scan. Then:

find ./ -type f -exec md5 {} ; | awk -F '=' '{print $2 "t" $1}' | sort | tee duplicates.txt

You’ll find a TXT file showing duplicates in the location you specified.
