How to remove origin from git repository

Question

Basic question: How do I disassociate a git repo from the origin from which it was cloned?

git branch -a shows:

* master
  remotes/origin/HE         


        

Answer 1

Fairly straightforward:

git remote rm origin

As for the filter-branch question - just add --prune-empty to your filter branch command and it'll remove any revision that doesn't actually contain any changes in your resulting repo:

git filter-branch --prune-empty --subdirectory-filter path/to/subtree HEAD
