Command-line interfaces - SS1 ICT Lesson Note

Command-line interfaces (CLIs) provide a way for users to interact with a computer or software application by entering commands in a text-based environment.

Command line interfaces (CLI) allow users to interact with the computer through text-based commands. CLIs are often preferred by advanced users and developers due to their flexibility and efficiency. 

Examples of command-line interfaces:

1. Windows Command Prompt: The Windows Command Prompt allows users to execute various commands to interact with the Windows operating system. Users can perform tasks such as navigating the file system, running programs, and managing files and directories.
2. Unix/Linux Terminal: Unix and Linux terminals provide a powerful command-line interface for managing the operating system. Users can perform tasks like file manipulation, process management, networking, and software installation using commands like ls, cd, grep, and sudo.
3. macOS Terminal: Similar to Unix/Linux terminals, the macOS Terminal provides access to the command-line environment on Mac computers. Users can execute commands to perform tasks like file management, system configuration, and software development.
4. Windows PowerShell: PowerShell is a more advanced command-line shell and scripting language developed by Microsoft. It allows users to manage and automate system tasks, interact with services, and perform administrative tasks more efficiently.
5. Command Prompt on Embedded Systems: Many embedded systems and devices, such as routers and network switches, provide command-line interfaces for configuration and management. These CLIs allow administrators to configure network settings, security parameters, and more.
