How can I replace all instances of a string in my entire home directory?

I am working on a library, and I made a major change. All my projects import github.com/retep-mathwizard/utils/src/..., but I have shortened my projects to github.com/retep-mathwizard/utils/.... I need to find every occurrence of it starting at ~, and replace all occurrences. Is there a way to do this?
