What does this do: git branch -f
branch, git
Solution
The `-f` argument stands for `--force`.
- If a branch called `master` already exists, git will not allow you to overwrite it, unless you use `-f`.
- Second parameter (`sub-branch`) will be used to determine where the `master` branch's `HEAD` should be pointing to.
Problem
I'm trying to figure out how to use this command properly. I believe this is the command and flag I want to essentially make one branch into my other branch (basically delete a branch and create a new branch with the same name with the files of another branch), but I don't know for sure, or if I have the syntax correct. If I do this: ``` git branch -f master sub-branch ``` Will it remove all of the files from master and fill it with the files from sub-branch?
