git config --global core.filemode false does not work with git diff

Question

I have set

 git config --global core.filemode false

And checked that my config is ok with git config -l

...
core.repositoryformatversion=0
core.filemode=false
core.bare=false
core.logallrefupdates=true
core.ignorecase=true
core.autocrlf=false
...

But when I type git diff foo I get this:

diff --git a/.gitignore b/.gitignore
old mode 100755
new mode 100644
diff --git a/Makefile b/Makefile
old mode 100755
new mode 100644
diff --git a/config.ini b/config.ini
old mode 100755
new mode 100644
...

I imported a remote repository inside mine with:

git remote add foo //192.168.1.42/foo/
git pull foo master
git checkout -b foo foo/master
git diff master

Where is my mistake?

Were you able to make it work? The answer below has no effect in my case — Robert Sinclair, Jul 21 '21 at 13:21

Make sure you don't have multiple entries of that setting and set it locally instead of globally:

git config --global --unset-all core.filemode
git config --unset-all core.filemode
git config core.filemode false

@nowox can you try a `git reset -- .gitignore`? And `git add -- .gitignore` again? – VonC Jun 01 '15 at 16:46
my `git status` gives `On branch foo\n nothing to commit, working directory clean` – nowox Jun 01 '15 at 16:47
@nowox strange, what version of Git are you using? Do you see the same with Git 2.4.2 (https://github.com/git-for-windows/git/releases) – VonC Jun 01 '15 at 16:52
Same behavior between 2.1.4 and 2.4.0 – nowox Jun 01 '15 at 17:05
I don't have it installed yet – nowox Jun 01 '15 at 17:05
@nowox sure: unzip it anywhere you want, add it to your path and done. – VonC Jun 01 '15 at 17:06
@DavidT It makes sure no other configuration exists elsewhere and the only the local config prevails. – VonC Mar 28 '19 at 21:57
@IulianT OK, could you describe your context in a separate question? (OS, git version, command typed, expected result vs. what you actually get). – VonC Aug 12 '22 at 07:54
oddly, second line did it for me, while adding 3 line makes mode message appear again – Joe Half Face Mar 26 '23 at 09:56
