git filter-branch remove all submodules from my repo

Question

Hello I have successfully rewrote history and got the 5 folders I wanted to extract using git filter-branch -f --prune-empty --tree-filter 'rm -rf <all unwanted dirs>' and kept all git history.

The only remaining issue are submodules, I sill have commits doing

Subproject commit <hash>

and I want to completely remove ALL of those submodule commits from my git history, how can I accomplish this?

Answer 1

I have done it with

git filter-branch -f --prune-empty --tree-filter '
    git submodule deinit -f .
    git rm -rf lib && rm -rf lib
    find . -name .gitmodules -delete' HEAD

Assuming that all of my submodules were located in lib directory
