Have you ever come into a situation that a production issue happened in the last two months but it was automatically fixed after that? Then, you brainstorm that it might a good side-effect change in a file which fixed that issue inadvertently. To investigate the issue with a hard-work you need a tool like viewing all changes in the last two months. And in this post, I will show you two handy tools: Git command will list all commits for a file: git log --oneline --follow -- the-path-to-the-file For example, you have a file, named: foo.js in a src/app folder. The command you should type is: git log --oneline --follow -- src/app/foo.js It's a handy little command for those times where you want to see all the Git commit ids associated with a file. Gitk command A website needs a browser, and a file also needs Gitk to view too. You can read more in git docs In Mac, if you do not still have it, then run brew install git-gui to install it. You can read this StackOverflow post in case you have trouble during the installation. So, to view the changes in a foo.js visually, just run the below command: gitk src/app/foo.js
