Question

How do I view previous diff commits using Git?

I have a file that I've made several commits on, but I want to view previous versions of the file AND its diff's at different stages. Seeing where I made mistakes and how I fixed them is really helping my code. By the way, I'm using Tower as a GUI on top of Git.

Answer 1

git log --full-diff -p your_file_path

Answer 2

You need git log. If you were interested in file SOMEFILE use

$ git log -p SOMEFILE

The -p option displays the patch which is probably the diff you are looking for.

Answer 3

If you don't want to specify a particular file, and see the diff for all files changed, just use

$ git log -p
