the safest way without losing commits :)

bypass husky precommit & prepush (AT YOUR OWN RISK: if you need to push do it ASAP without getting stuck waiting for husky rules haha)

git commit -m "message" --no-verify

git push --no-verify

If you encounter the "fatal: refusing to merge unrelated histories" error even when attempting to pull changes from the remote repository, you can try the following steps to resolve the issue:

1. Fetch the remote repository's changes without merging them:

   git fetch --all

2. Create an empty commit to establish a common root for the branches:

   git commit --allow-empty -m "Empty commit"

3. Merge the remote branch into your new branch using the --allow-unrelated-histories flag:

   git merge origin/main --allow-unrelated-histories

4. Resolve any merge conflicts if they occur. Use a text editor or Git tools to manually resolve conflicts in affected files.

5. Commit the changes

   git commit -m "Merge unrelated histories"

6. Push the changes to the remote repository:

   git push origin your-branch

accidentally commit unwanted files and want to back to unstaged area

git reset --soft HEAD^

accidentally push unwanted files and want to remove from git history

example .env file

1. add filename to .gitignore file

   optional : if the file may exist under certain conditions, and want to prevent it from being tracked to git

2. untrack and remove file from commit

   git rm -r --cached .env

3. commit changes

   git add . && git commit -m "remove unwanted files"

4. remove file from all git commit history

   git filter-branch --index-filter "git rm -rf --cached --ignore-unmatch .env" HEAD

5. push to origin to implement removed file to remote git history

   git push --force

6. clear the backup

   git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d
