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-only --diff-filter=ACMR ${revision} HEAD 

It returns a list of files, including the submodule-path, but not the files within.

Example: I've updated a submodule. I commited the super-project. Now I want to get a list of all files which have been modified.

Do you know a way to get this done?

Answer 1

Update 2017: as I mentioned in "see diff of commit on submodule in gitlab",

• Git 2.11 (Nov. 2016) introduces

  git diff --submodule=diff 

• Git 2.14 (Q3 2017) will improve that by recursing into nested submodules.
  See commit 5a52214 (04 May 2017) by Stefan Beller (stefanbeller).

Original 2012 answer (pre 2017 Git 2.14)

Maybe a simple line would be enough:

git submodule foreach --recursive git diff --name-status 

That would actually list files in submodules within submodules.
(The --recursive option comes from git1.7.3+)

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
