Every now and then I find myself wanting to create a new empty branch in an
existing repository. It’s useful for things such as GitHub Pages so you’re
able to keep your content source in the master branch while only keeping the
output in the
gh-pages branch. I’ve also used it for testing a complete
rewrite of a code base without the overhead of creating a new repo and copying
This is a pretty straight forward trick to do. You create the branch by indicating you want the new branch to be an orphan by passing the ‘–orphan’ flag like so:
git checkout --orphan NEW_BRANCH_NAME
This leaves all the files in place but effectively uncommitted like you just initialized a new repository. Add and commit any files you’d like to keep then delete the rest, everything will still be preserved in the original branches.
With that done you should be able to easily switch just using a normal ‘checkout’ between your normal branches and this new tree.
