Using git diff in same file between first and last commit

Question

I have a text file (.yml) that I enter some texts to my system use. But now we need to know what new lines at once. I thought to use git to solve our problem, but I cant find a clarified command to do this.

Is this possible?

Answer 1

You can get a list of the commits withs something like so:

git log --abbrev-commit --pretty=oneline

Which should something like this:

commitD Description
commitC Description
commitB Description
commitA Description

Choose your two commits and substitute them below:

git diff <commitA>..<commitB> -- /path/to/file
