How to view the duplicates from sub-directories? Just use -r option like below. It shows the duplicates from the parent directory only. Sample output from my system: /home/sk/Downloads/Hyperledger.pdfĪs you can see, I have a duplicate file in /home/sk/Downloads/ directory. Just run the following command to find out the duplicate files in a directory, for example ~/Downloads. On RHEL, CentOS: $ sudo yum install epel-release $ sudo yum install fdupesįdupes usage is pretty simple.

It is free, open source utility written in C programming language. Remove Duplicate Files From Your Android With Duplicate Files Fixerįdupes is yet another command line utility to identify and remove the duplicate files within specified directories and the sub-directories.If you do not want to ignore empty files and delete them along with all duplicates, run: $ rdfind -deleteduplicates true -ignoreempty false ~/Downloadsįor more details, refer the help section: $ rdfind -help To delete all duplicates, simply run: $ rdfind -deleteduplicates true ~/Downloads If you don't want the old files anymore, just delete duplicate files instead of replacing them with hard or soft links.

You can remove the duplicates manually if you want to.Īlso, you can -dryrun option to find all duplicates in a given directory without changing anything and output the summary in your Terminal: $ rdfind -dryrun true ~/Downloads # duptype id depth size device inode priority nameĭUPTYPE_FIRST_OCCURRENCE 1469 8 9 2050 15864884 1 /home/sk/Downloads/tor-browser_en-US/Browser/TorBrowser/Tor/PluggableTransports/fte/tests/dfas/test5.regexĭUPTYPE_WITHIN_SAME_TREE -1469 8 9 2050 15864886 1 /home/sk/Downloads/tor-browser_en-US/Browser/TorBrowser/Tor/PluggableTransports/fte/tests/dfas/test6.regexĭUPTYPE_FIRST_OCCURRENCE 13 0 403635 2050 15740257 1 /home/sk/Downloads/Hyperledger(1).pdfĭUPTYPE_WITHIN_SAME_TREE -13 0 403635 2050 15741071 1 /home/sk/Downloads/Hyperledger.pdfīy reviewing the results.txt file, you can easily find the duplicates. You can view the name of the possible duplicate files in results.txt file. $ rdfind ~/DownloadsĪs you see in the above screenshot, Rdfind command will scan ~/Downloads directory and save the results in a file named results.txt in the current working directory.

If you have two or more equal files, Rdfind is smart enough to find which is original file, and consider the rest of the files as duplicates. Rdfind uses ranking algorithm to classify original and duplicate files. It compares files based on their content, not on their file names. Rdfind, stands for redundant data find, is a free and open source utility to find duplicate files across and/or within directories and sub-directories. These three utilities are free, open source and works on most Unix-like operating systems.
