Version Control 8

This is a follow up question to Version Control 7.

You’re working late and you sit down to edit predict_richness.sh. You open the file in your editor, reach for your cup of coffee, knock it over onto your computer and in all of the excitement somehow delete the contents of the file and save it (go ahead, open it, delete the contents, press save). Not to worry, you’re using version control. Take a deep breath, dry off your computer, revert the changes using git checkout, and reflect on how using version control makes you just like Superman in Superman 1 because it’s like you made time go backwards.
