Move accidental commit on "master" to another branch [Git]
In the situation you've accidentally already committed changes to your "master" branch and want the moved to a seperate branch:
git branch [NEW_BRANCH_NAME] # Create new branch with the changes you just committed
git reset --hard HEAD~[NUM_COMMITS] # Go back [NUM_COMMITS] commits. You *will* lose uncommitted work.*1
git checkout [NEW_BRANCH_NAME] # Checkout the newly created branch that contains your modifications
