How do I get the correct modification status after running git diff?

Hello,

I have added a new file to a working repository, and would like to run a diff between the last commit and whatever is int he working tree, along with an identification of what kind of a modification it was. Currently, I am adding all files to the index with the -N option, and then running a git diff --name-status. This works well for existing files that have been modified or deleted, but fails if a file is rename or is added. Does anyone know of the right way to do this? The commands I am using to add and diff newly added files are as follows in the sequence shown.

Commands: echo "this is a new file" > file1.xml git add -N . git diff --name-status

The output is : M file1.xml

I want the status to show A for the newly added file (and R for renamed files but I don't know if that's possible).

Thank You, Jawad.
