add a
By this point, we've added 3 commits to this repo. Now, I wanna squash the last two commits for b and c into a single commit.
Type git rebase -i head~2, which will bring up an interactive thing:
pick <hash-1> add b
pick <hash-2> add c
Just pick the first one and squash the rest
pick <hash-1> add b
squash <hash-2> add c
Next, you'll be taken to a window where you can completely update the commit message that will encapsulate this whole change. Add a commit message and :wq.
