title: Git how to prevent load some changes
body: <p>Is there any tool that can help me prevent error with changing base urls. Sometimes I need to test production url instead of development url sometimes. I have two different paths for the same baseURL variable. But what I want is prevent to upload this changes to github. How can I select some snippet of text to just prevent this changes to be commuted. So actually before commit this changes I need to rollback baseUrl to previous state. So I know for sure I can track it manually and see if I still have another url string, but maybe we can add some thing at start that will notify me that I will need to change that url before committing.</p>
