git log - find additions of a specified string

Question

How can I search through my git history for commits containing additions only of a specified string?

For example, how could I find all commits that contain additions of System.out.println or debugger.

I know of the -S argument that can be supplied to git log, but it includes all commits containing additions or subtractions of the specified string.

Is there a natural way to do it?

Answer 1

Try the following one -

To search the commit log for the given string:

git log --all --grep='specific string'

To search the actual content of commits in the repository:

git grep 'specific string' $(git rev-list --all)

It will give all the instances of the given text, the containing file name, and the commit.

Hope this is what you want.
