Sometimes it's expedient to quickly recall a previous command without the need to retype it. The most common means of doing this is to use the up arrow. Let's try it:
john-williams@codermerlin:~$ ls
Now, let's repeat the command, but rather than typing in ls again, try pressing the up arrow key:
john-williams@codermerlin:~$ ↑
Try pressing the ↑ and ↓ several times.
Observe
Observe, Ponder, and Journal: : Section 5
- What happens each time you press the ↑?
- What happens each time you press the ↓?
