(git) diff output relative path?

Question

I need to get some diffs in my repo that are not relative to the base of the repo, but instead relative to a given base or given path.

By default I get:

git diff diff --git a/path/to/file b/path/to/file index 0cc125e..9bf911e 100644 --- a/path/to/file +++ b/path/to/file 

But what I want is something like:

git diff --prefix=/new/path/to diff --git a/new/path/to/file b/new/path/to/file index 0cc125e..9bf911e 100644 --- a/new/path/to/file +++ b/new/path/to/file 

I have looked over the --relative option (not what I am looking for), the --src/dst-prefix (these can only change the "a" or "b" parts. Am I missing something basic?

git diff prints paths (of changed files) from the root of the repo - no matter where you are when executing the command.

git diff --relative will print paths from the dir you are in.

So if you need paths not starting from the repo-root move down (cd) to the directory (within your repo tree) where you with your paths to start from.
