I have a basic understanding of a file system, programs, and all these kinds of machinery. Now to handle all of this on my computer, I do need a shell language. A shell language is also a programming language, so ideally, I should be a programmer too. But that's not all: additionally, I should know a knowledge CLI options of such common utilities as `find`, `grep`, and `ls`. Ideally, the most common options should reside in my brain memory just not to waste my time surfing StackOverflow. By the way, StackOverflow is also an almost totally programmer's resource. The farther we go, the more absurd the situation becomes. I can say, computers are totally usurped by computer programmers, The Gods of Bits & Bytes (TM). Users can either scroll the mouse, or please programmers to do stuff, or go to hell. If Logos was the reality, I would say to my computer "Please, move all files from the directories X, Y, and Z to the directory Q, if they have the write and read bits set on, and please do it in 5 mins". No knowledge of a myriad of command-line utilities required, no shell language and even no typing on a computer.
