Four commands. You'll see exactly what to type before you type it — this lesson is about building the muscle memory, not guessing blind.
Before We Start
What's a terminal, anyway?
A terminal is a text-only way to talk to a computer — no clicking, no menus. You type a command, press Enter, and the computer talks back.
Click inside the black box below first. That's how the terminal knows you're talking to it. A blinking cursor means it's listening.
Every line starts with a prompt — in this lesson it looks like student@aisem:~$. That's just "who you are, where you are." You don't type that part, only what comes after it.
This one's a simulator running in your browser. Nothing is real and nothing you type can break anything — type freely.
student@aisem:~$ whoami
student
↑ you typed "whoami" after the prompt, pressed Enter, and it printed the answer
Done
That's the loop.
See the command, type it yourself, press Enter, get confirmed. Every lab in this track — bash, Python, SQL, git — runs on this same loop, just with new commands each time.
