For those who don’t know this, you can use you UP arrow on your keyboard to cycle through previous commands you’ve entered in the terminal. Your “bash history” records them, and you’ll be presented with them in the order of last used first. If you go too far, use your DOWN arrow to find the command you passed. Similarly, if you decide to type in a new command, just use the DOWN arrow to get past the previous entries and back to an empty prompt.
