Considering the fundamental operations of a computer, what is the immediate effect of pressing the Tab key within a command-line interface (CLI) or terminal?​

Correct option is C

The correct answer is (c) It attempts to auto-complete the currently typed command or filename.

• In a command-line interface (CLI) or terminal, pressing the Tab key triggers an auto-completion feature.

• When you type part of a command or filename and press Tab, the system tries to complete the command or filename for you based on available matches. If there is more than one match, the system might show a list of possible completions.

• This feature helps increase efficiency by reducing the need to type full commands or filenames.

Information Booster:

• Tab Completion: This feature is widely used in many command-line interfaces like Linux, macOS, and Windows PowerShell to speed up the typing process and reduce errors.

• Autocomplete Behavior: If multiple commands or filenames match the typed portion, pressing Tab twice typically shows a list of all matching possibilities.

• CLI Usability: It enhances the user experience by allowing faster navigation through directories and easier execution of commands.

Additional Information:

• The Tab key also helps in navigating directories in some file explorers, but in a terminal, it is specifically used for command or filename completion.

• This feature is a part of the shell’s command-line interface environment, and it's available in most Unix-like operating systems and modern Windows command prompts.
