set a Git config recursively for all submodules

Question

I need to run the command:

git config core.filemode false

The problem is that I have a few projects with at least ten submodules each. For some reason, all the submodules have that value set to true so I would have to remove/update that config manually.

Is there a way to tell Git to set a config value to all submodules?

Or remove it from the submodules so that the containing repo's settings are not overwritten?

Answer 1

You can use the git submodule foreach command for this: https://www.kernel.org/pub/software/scm/git/docs/v1.6.1.3/git-submodule.html

You can provide an arbitrary shell command as a parameter, in your case something like this:

git submodule foreach --recursive git config core.filemode false

This will execute git config core.filemode false in each of the submodules of the current Git repo.
