Compare Files in Linux With These Tools

Whether you’re a programmer, creative professional, or someone who just wants to browse the web, there are times when you find yourself finding the differences between files.

There are two main tools that you can use for comparing files in Linux:

  • diff: A command line utility that comes preinstalled on most Linux systems. The diff command has a learning curve.
  • Meld: A GUI tool that you can install to compare files and directories. It is easier to use, especially for desktop users.

But there are several other tools with different features for comparing files. Here, let me mention some useful GUI and CLI tools for checking the differences between files and folders.

Note: The tools aren’t ranked in any particular order. Choose what you find the best for you.
