This can be a simple frequency-of-use issue. Non-programmers might need a command-line solution once or twice a year. It's hard to remember a series of steps that you don't frequently perform. For example, you can theoretically know how to change a tire, or how to use Photoshop to replace a color in an image, or how to troubleshoot a printer. But you only run through that series of steps occasionally, when there's a specific problem to solve.
