Overwrite everything in master with another branch in git

Question

I have a very out of date master branch in a git repository.

All of my work has been done in another branch.

What is the best way to merge the

Answer 1

A complete overwrite isn't merging the other content, it's abandoning it.

git checkout -B master anotherbranch

This has the advantage over a delete-and-recreate of retaining your branch settings and reflogs.

If there's some administrative requirement to retain worthless commits in your history, follow that with git merge -s ours master@{1}. I prefer this sequence because it generates an unusual merge message, which will alert scanning --oneline logs that the merge is unusual.
