CLI
/ˌsiː-ˌɛl-ˈaɪ/
n. “Type it, execute it, watch it happen.”
The CLI, or Command-Line Interface, is a text-based interface used to interact with a computer or software by typing commands rather than using graphical elements like buttons or menus. It is the original way humans communicated with machines before GUIs became ubiquitous, and it remains a powerful tool for developers, system administrators, and power users.
