git: show all modified files - staged and not staged

Question

I need a command which gives me all modified files - this includes staged (i.e. newly added files) and non-staged changes - in a plain list which I can use in a script. While this question might sound familiar I only find commands that come close to what I want to do:

git ls-files -m

.. lists (non staged) modifications but ignores staged and newly added files

git diff --name-only

.. will also only list non staged modifications

git diff --name-only --cached

.. lists only staged modifications but omits files with non-staged modifications

git status --porcelain --untracked-files=no

.. outputs all files I want to see but adds the status

I could play with git status of course and cut the first entry but since I want to integrate this command in a CMake script which will be used on windows, too. So one single command would be fine..

Answer 1

git diff --name-only HEAD

looks like what I'm looking for - but I'm not sure yet. If someone comes up with some elaboration I'll take his/her answer :)
