Git Overwrite master with branch

git branch -f master dev_branch will rewrite local master branch.

git push remote +dev_branch:master will rewrite remote branch.

• NOTE: If the above doesn't work, the name remote could be origin for you (i.e. git push origin +dev_branch:master)

To completely replace the master branch with the contents of any other feature_branch you can also use:

git checkout feature_branch
git merge -s ours --no-commit master
git commit      # Add a message regarding the replacement that you just did
git checkout master
git merge feature_branch
