Git Diff Matches Paths 📁

Today I learned that the git-diff command accepts a ` argument. I used this knowledge to construct a command that runs only the RSpec test files on my branch that differ from master. ``` (not-master)$ git diff master --name-only spec | xargs rspec ``` This is handy on a big test suite; when you can't run every test, make sure you run the ones that you have changed. Seeman git-diff` for more info.
