Set 1 of 3, preserve files (12 bytes each):Īlternatively, the -N option can be used, which will preserve the first file out of each set, but won’t prompt: $ fdupes -SdN. When you run this, you will be prompted for which file you wish to keep out of each set of duplicates that have been identified: $ fdupes -Sd.

Using fdupes to search for duplicate files recursively or in multiple directories ħ duplicate files (in 3 sets), occupying 102 bytes. We can use the -m option to get this information, or summary: $ fdupes -Sm. fdupes has grouped all identical files within this directory together which shows that text1.txt for example, is identical to test2.txt. I’ve used the -S switch to also output the file size. So what happens if we now run fdupes in this directory? $ fdupes -S. I created the files by echoing the same words into each group of files, this is a quick and easy way to generate a bunch of identical files: $ for i in.

Lets say we have a bunch of text files in a directory, and we want to find any which are duplicates. But, how do we use fdupes to find duplicate files? Find Duplicate Files using fdupes Examples OK, so that’s how to install fdupes on Linux. We can confirm it is installed and working by running the fdupes version command: $ fdupes -version To install fdupes on Ubuntu systems you can use: $ sudo apt-get install fdupes Or, on recent systems you may need to use dnf install fdupes. Once done, to install fdupes use: $ yum install fdupes To install fdupes on RedHat, CentOS or Fedora, you will first need to enable the epel respository: $ yum install epel-release In this section we will look at how to install fdupes and how to use fdupes to find duplicate files on Linux. fdupes uses a number of techniques to determine if a file is a duplicate of another. Using fdupes to search for duplicate files recursively or in multiple directoriesįdupes is a Linux tool which is able to find duplicate files in a specified directory or group of directories.Find Duplicate Files using fdupes Examples.How to Find Duplicate Files with fdupes. ![]()
