For example, if your commit history is A-B-C-D-E-F with F as HEAD, and you want to change the author of C and D, then you would...

Specify git rebase -i B
change the lines for both C and D to edit
Once the rebase started, it would first pause at C
You would git commit --amend --author="Author Name <[email protected]>"
Then git rebase --continue
It would pause again at D
Then you would git commit --amend --author="Author Name <[email protected]>" again
git rebase --continue

Vagrant Cheat Sheet

Essential Commands

vagrant up - Starts your virtual machine.
vagrant status - Tells you if your virtual machine is running.
vagrant suspend - Saves the state of your virtual machine. (Similar to putting it to sleep.)
vagrant resume - Restores a suspended virtual machine. (Similar to waking it up from sleep.)
After your first vagrant up, a suspend/resume operation only takes a few seconds.
Destroying your virtual machine means that you'll need to wait through the ~20 minute boostrap process the next time that you vagrant up.
