How do I make a branch at an old commit which I have already made changes to?

Question

Here's what I'm doing. My master branch has a bug in it and I have identified an old commit using git bisect which is the latest commit which does not exhibit the bug.

I have had this commit checked out and made a few fixes to eliminate compiler warnings, so I'd like for these changes (unrelated to the original bug) to eventually get included.

What I want to do at this point is make a new branch here, which will have this old commit (the last non-bugged commit) as parent.

I suspect the answer is to just commit here, using -b branchname . Is that correct?

Answer 1

There is no commit -b . You should git checkout -b branchname , then git commit as usual. This will leave you with a new branch with one new commit on it, with the commit you previously checked out as its parent.
