Compare files from the command line

Last modified: 11 February 2024

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 IntelliJ IDEA 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
idea64.exe diff <path1> <path2> [<path3>]
Example
>
idea64.exe diff C:\MyProject\Readme.md C:\MyProject\Readme.md.bak
