Why Should I learn Command Line?

I’m currently learning web development and Command Line appeared as one of it’s topics so I am curious on how I can use it in web development.

There are many aspects to this question. The command line is an incredible powerful tool, useful to know.

The command line gives flexibility which can speed up development.

Web servers (which run your website) run in headless mode (which means no GUI), so then the command line is essential.
