A command line interface (CLI) is making a comeback as users become increasingly dependent on search functionality in digital products. CLIs were once widely adopted but faced challenges due to their steep learning curve and text-only interface, which limited user interaction. However, with advancements in technology, CLIs are regaining popularity as GUIs struggle to scale to meet the demands of modern systems. The author predicts that CLIs will become more powerful and user-friendly, particularly in areas where search functionality is essential. A new paradigm called CLUI (Command Line User Interface) is being developed to address these challenges, prioritizing approachability, discoverability, and interactivity. CLUI aims to provide a seamless experience for users to interact with commands, making it easier to navigate complex systems. By integrating CLUI into the Repl.it platform, the authors hope to improve user interface scalability and reduce clutter in traditional GUIs.
