why git shows such log in my commit log tree?

Question

As you can see, there is many files remove and add same code line, and it happened a lot.

I wonder why and how to avoid this?

Answer 1

This generally happen when git changes the eol (end-of-lines) on all files, because of a global config like core.autocrlf.

Since all the lines are modified, git considered they are all "removed" and replaced with new ones.

Try:

git config --global core.autocrl false

Then clone again your repo, work on it, commit and see if you still list similar logs.
