CLion 2021.2 Help

Compare files from the command line

Open the diff viewer to compare two or three files from the command line. For example, you can compare the current version of a file with its backup, or your local copy of a file with its copy from the remote repository or its copy from another branch.

You can find the executable for running CLion in the installation directory under bin. To use this executable as the command-line launcher, add it to your system PATH as described in Command-line interface.

Syntax
clion64.exe diff <path1> <path2> [<path3>]
Example
clion64.exe diff C:\MyProject\Readme.md C:\MyProject\Readme.md.bak

By default, CLion does not provide a command-line launcher. For information about creating a launcher script for CLion, see Command-line interface.

Syntax
clion diff <path1> <path2> [<path3>]
Example
clion diff ~/MyProject/Readme.md ~/MyProject/Readme.md.bak
