Magento 2 : Create custom patch and apply on specific module

This article will help you to create a custom patch & apply on the specific module.

Let’s suppose you want to modify some code in this file

vendor/ezimuel/ringphp/src/Client/CurlMultiHandler.php

Create a copy of that file with your changes on it:

vendor/ezimuel/ringphp/src/Client/CurlMultiHandler_cust.php

Then you need to run below command on the Magento root directory:

diff -u vendor/ezimuel/ringphp/src/Client/CurlMultiHandler.php vendor/ezimuel/ringphp/src/Client/CurlMultiHandler_cust.php > custom_change.patch

1	diff -u vendor/ezimuel/ringphp/src/Client/CurlMultiHandler.php vendor/ezimuel/ringphp/src/Client/CurlMultiHandler_cust.php > custom_change.patch

And you will get the below output :
