Lesson 9: Deleting Safely with rm

This is the most safety-critical lesson. `rm` deletes a file — and the terminal has no recycle bin. What's deleted is gone. We'll learn to delete, but mostly learn when to stop and think twice.

rm isn't tossing into a bin (you can fish it back). rm is shredding a document. There's no way back.

rm: A command that deletes a file permanently, with no recycle bin
rm -i: A delete that asks for confirmation before each file
rm -r: A recursive delete of a folder and everything in it
