Git diff says subproject is dirty

Question

I have just run a git diff, and I am getting the following output for all of my approx 10 submodules

diff --git a/.vim/bundle/bufexplorer b/.vim/bundle/bufe         


        

Answer 1

A submodule may be marked as dirty if filemode settings is enabled and you changed file permissions in submodule subtree.

To disable filemode in a submodule, you can edit /.git/modules/path/to/your/submodule/config and add

[core]
  filemode = false

If you want to ignore all dirty states, you can either set ignore = dirty property in /.gitmodules file, but I think it's better to only disable filemode.
