How to identify delta changes between two commits in git

Question

I am trying to identify the delta changes whenever I commit something to gitlab. The commits can be greater than one.

I am trying to find answer similar to below question Copy differing files between two commits to a specific folder using Git

The solution described in above question says it should give me delta changes only but i am getting the whole files. I require delta changes only.

eg If i execute below commands

git clone <repository location>
git checkout <SHA of old commit>
git diff --name-only <SHA of old commit> <SHA of newer commit> | xargs git checkout-index -f --prefix='C:\changes\'

I get the changed file in folder location C:\changes\. But i need the changed files with delta changes only and not the whole file content. Not sure what i am doing wrong.

Any suggestions would really help.

Thankyou.

In shell you can do git diff first-commit-sha1..last-commit-sha2 to get changes between sha1 and sha2.
