How to exclude commit messages from git log when printing changed files only?

I am trying to get a list of files that have changed on a branch since some date. This is what I have now:

git log --since="2022-10-13T17:40:05.232777" --name-only --pretty=format:'%f'

And that prints:

Even-more-test-files
python/tests_index/secondtestfile.txt
python/tests_index/teeeeeeeeeest.txt

More-test-files-for-git-log
python/findtest.py

Add-some-test-file
python/tests_index/testfile.txt

That’s weird. The dash separated strings like More-test-files-for-git-log are commit messages, except for some reason spaces are replaced with dashes. What I want is just this:

python/tests_index/secondtestfile.txt
python/tests_index/teeeeeeeeeest.txt
python/findtest.py
python/tests_index/testfile.txt

No commit messages. No extra newlines. Just a list of files that have changed via a commit on this branch since the date I have given.

How to fix the --pretty argument so that I get what I want?

>Solution :

--pretty=format:'%f'

The dash separated strings like More-test-files-for-git-log are commit messages, except for some reason spaces are replaced with dashes.

That’s what you asked for:

%f
    sanitized subject line, suitable for a filename

How to fix the --pretty argument so that I get what I want?

Use --pretty=format: (or --format=).
