git append <branch>

The append command creates a new feature branch with the given name as a direct child of the current branch and brings over all uncommitted changes to the new branch. Before it does that, it syncs the current branch to ensure commits into the new branch are on top of the current state of the repository.

Example

Consider this branch setup:

main
 \
  feature-1

We are on the feature-1 branch. After running git append feature-2, our repository will have this branch setup:

main
 \
  feature-1
   \
    feature-2

Variations

If push-new-branches is set, git append creates a remote tracking branch for the new feature branch. This behavior is disabled by default to make git append run fast. The first run of git sync will create the remote tracking branch.
