Is it possible to make a commit between the old two commits?

Question

git

Let 's say
git init -> commit A -> commit B -> commit C
can I cram, for example, commit D between commits A and B? to get it like this:
git init -> commit A -> commit D -> commit B -> commit C

Can I cram, for example, commit D between commits A and B? to make it look like this:

You can with git rebase. The complexity of stuffing directly depends on how many common lines change D, B and C. If they are completely independent, git rebaseit will do everything itself, if not, you will have to resolve conflicts.
