Shell/Command Line Lesson Notes

Command Line "Magic"

"What's the difference between a terminal and a shell?"

A terminal is the computer application you open (e.g. macOS Terminal, iTerm, etc). You need some kind of terminal app to be able to interact with a shell.

• These are technically called "terminal emulators". They emulate the old-school physical terminals that allowed you to interact with "shell-like" operating systems like MS-DOS.
