git rewrite history - how to re-order commits in Git non-interactively

Question

What non-interactive git command(s) achieve the change from Before to After?

Before:

A---B---C---D

After:

A---C'---B'---D'

Answer 1

In your case, you can rebase interactive: git rebase -i HEAD~4 Then you can just reorder your picks

For example lets add three more files to our branch:

git add A
git commit -m "A"

git add B
git commit -m "B"

git add C
git commit -m "C"

Your shortlog will be:

$ git shortlog
 (3):
      A
      B
      C

If you want to reorder B with C:

$ git rebase -i HEAD~2
pick 1f9133d B
pick 33f41be C

You just re-order them to be:

pick 33f41be C
pick 1f9133d B

After you're done writing, see the shortlog:

$ git shortlog
 (3):
      A
      C
      B

You can do the same thing with all the commits by re-ordering. It is like what you see is what you get, which is pretty cool :)
