git: list all files added/modified on a day (or week/month...)

I'd use diff to yield the file list directly, e.g:

git diff --name-only "@{3 days ago}" "@{2 days ago}"

changelog.txt
newfile.txt

In case you're curious which file got modified or added, use --name-status instead:

git diff --name-status "@{3 days ago}" "@{2 days ago}"

M       changelog.txt
A       newfile.txt

Maybe this:

  git log --since="1 day ago" --name-only --pretty=format: | sort | uniq

Include --until if you want for a day, week etc.
