Git: How to rebase to a specific commit?

Question

You can avoid using the --onto parameter by making a temp branch on the commit you like and then use rebase in its simple form:

git branch temp master^
git checkout topic
git rebase temp
git branch -d temp

You can even take a direct approach:

git checkout topic
git rebase <commitB>

Use the "onto" option:

git rebase --onto master^ D^ D

The comment by jsz above saved me tons of pain, so here's a step-by-step recipie based on it that I've been using to rebase/move any commit on top of any other commit:

1. Find a previous branching point of the branch to be rebased (moved) - call it old parent. In the example above that's A
2. Find commit on top of which you want to move the branch to - call it new parent. In the exampe that's B
3. You need to be on your branch (the one you move):
4. Apply your rebase: git rebase --onto <new parent> <old parent>

In the example above that's as simple as:

   git checkout topic
   git rebase --onto B A
