Purge a file from history

• Use git rm --cached --ignore-unmatch <path> to delete the file in the specified <path>.
• Use git filter-branch --force --index-filter <command> --prune-empty --tag-name-filter cat -- --all to rewrite the branch's history, passing it the previous command.
• You can optionally use git push <remote> --force -all to force push the changes to the remote repository.
• ⚠️ WARNING: This is a destructive action that rewrites the history of the entire repository. Make sure you know what you are doing.

git filter-branch --force --index-filter \
  "git rm --cached --ignore-unmatch <path>" \
  --prune-empty --tag-name-filter cat -- --all
git push <remote> --force --all
Examples
git filter-branch --force --index-filter \
  "git rm --cached --ignore-unmatch config/apiKeys.json" \
  --prune-empty --tag-name-filter cat -- --all
# Purges `config/apiKeys.json` from history
git push origin --force --all
# Force pushes the changes to the remote repository
