git: list of all changed files including those in submodules

Question

I would like to get a list of all files, which have changed betweet two commits including those in submodules.

I know I can do this:

git diff --name-

You can find out what version a submodule was at, as of a given parent module commit, using git ls-tree:

subcommit=$(git ls-tree $parentcommit $submodulepath | awk '{print $3}')

So here's a script that should get you much of the way there, up to output formatting and such:

#!/bin/sh

function compare {
    if [[ -z "$3" ]];
        then git diff --name-only --ignore-submodules=all --diff-filter=ACMR "$1" "$2"
        else git diff --name-only --ignore-submodules=all --diff-filter=ACMR "$1" "$2" | awk -v r=$3 '{ print "" r "/" $0}'
    fi

    for submodule in `git submodule | awk '{print $2}'`
    do
        old=$(git ls-tree $1 $submodule | awk '{print $3}')
        new=$(git ls-tree $2 $submodule | awk '{print $3}')
        (cd $submodule; compare $old $new $submodule)
    done
}

compare "$1" "$2"

This will output all files like this (although Base is a submodule): HtmlTemplates/Css/Screen.css Base/Php/Classes/Helper.php
