Command Line
ELI5 — The Vibe Check
The command line is the place inside the terminal where you actually type your commands. Think of the terminal as the room and the command line as the microphone you speak into. You type a command, press Enter, and the computer does exactly what you said — no questions asked.
Real Talk
The command line (or command prompt) is the text-based input interface within a terminal emulator where users enter shell commands. Unlike graphical interfaces, it provides direct access to OS functions, file system operations, and process management through typed instructions parsed by the shell.
Show Me The Code
# The prompt shows you where you are, then you type a command:
~/projects/my-app $ npm run dev
~/projects/my-app $ git status
