The shell and the terminal
Use the Bash shell to control a computer with commands.
📖 Key ideas
- A shell reads commands and runs programs; Bash is the most common on Linux.
- The terminal is the window where you type commands.
- Commands have options and arguments: ls -l /home.
- Use man ls or ls --help for help.
- Tab completes names; up arrow recalls history.
💡 Real-life example: The shell is a waiter: you speak the order (command) and it brings what the kitchen (OS) makes.
