Removing history from git - git command fails

Question

Im trying to purge a projects bin directory from Git history. I have already added \'bin\' to .gitignore and run $git rm --cached -r bin successfully. Now I hav

Answer 1

Okay so all I needed to do was add the -r to the rm command part (as below). I guess this is because bin is a directory rather than a file, so it must be removed recursively as otherwise the files it contains (or the information about them) would be orphaned.

$ git filter-branch --force --index-filter \
  'git rm --cached -r --ignore-unmatch bin' \
  --prune-empty --tag-name-filter cat -- --all

I followed this with the below to push the changes to the remote repo on github

$ git push origin master --force

Answer 2

The only place it makes sense is after the git rm. I have not tried it myself but I think that should work?

$ git filter-branch --force --index-filter \
  'git rm -r --cached --ignore-unmatch bin' \
  --prune-empty --tag-name-filter cat -- --all
