Question

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?

Answer 1

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.
