The command-line interface (CLI) is an effective text-based user interface (UI). Today, many users rely on graphical user interfaces and menu-driven interactions, but some programming and maintenance tasks may not have a GUI, or at times, may experience slowness. In such scenarios, command-line interfaces can be used.
When working on the OpenShift Container Platform, a variety of tasks can be performed using CLI tools aside from managing clusters, applications, and so on.
