It is not as complicated as it looks! As a long time windows user I’m in the process of getting used to the command line and I love the simplicity and direct way of doing things. For some tasks and small programs it is amazing. Grep for example is something amazing that you couldn’t do in a windows type UI.
For other stuff like visualizing a directory tree you can always use a mouse interface. You’re rarely forced to use the terminal.
Nice feature. Is it reliable? I can imagine this being dangerous if someone finds out how to manipulate it to flag a malicious site as official.
