git diff on date?

Question

I\'m accustomed to running a git comparison that will allow comparison with local git revs like:

git diff HEAD HEAD~110 -- some/file/path/file.ext
         


        

Answer 1

What you want must be this.

git diff HEAD '@{3 weeks ago}' -- some/file/path/file.ext

You should compare with @{3 weeks ago}, not HEAD@{3 weeks ago}.

What is difference?

If you were on another branch 3 weeks ago, HEAD@{3 weeks ago} would point the HEAD of the branch, on the other hand @{3 weeks ago} would point the HEAD of the current branch.

You can also explicitly name the branch.

git diff HEAD 'master@{3 weeks ago}' -- some/file/path/file.ext
