• macOS: The Terminal application on macOS provides access to Unix-based shells.

How a CLI Works

In a CLI, users type commands at a prompt, and the shell (the program interpreting commands) processes them. The system then returns output, typically as text, directly in the terminal window. CLI commands interact very closely with the operating system kernel, providing fine-grained control over processes, files, permissions, and network configurations.

Key Components of a CLI

• Shell: The core program that interprets the commands you type and executes them (e.g., Bash on Linux, PowerShell on Windows).
• Terminal/Console: The window or interface that displays the CLI, where you type commands and see the output (e.g., Windows Command Prompt window, a PuTTY session).
• Commands: Specific, predefined instructions (e.g., dir or ls to list directory contents, copy or cp to duplicate files, ping to test network connectivity).

CLI Example in Action

To list the contents of the current directory in Windows Command Prompt, a user would simply type dir and press Enter. To duplicate a file named report.docx to report_backup.docx, they would type copy report.docx report_backup.docx.

Typical CLI Applications

• System Administration: Configuring servers (especially headless servers without a GUI), managing user accounts, installing software packages, or troubleshooting system boot issues.
• Automation: Writing scripts (e.g., Bash scripts, PowerShell scripts) to automate repetitive tasks like backups, software updates, log file cleanup, or routine system checks.
