How to apply a Git patch to a file with a different name and path?

Question

I have two repositories. In one, I make changes to file ./hello.test. I commit the changes and create a patch from that commit with git format-patch -1 HE

Answer 1

FYI: I recently had problems trying to download a patch from Github and applying it to a local file (which was an "override" in a new location).

git am wouldn't apply the patch either because the file was "not in index" or "dirty." But, I found that the simple patch command could apply the patch. It did prompt me for the name of the file to be patched.

Got the job done, anyway ...
