I cannot see how this article is defending UNIX only by talking about a single utility. It could be a better "defense" if it mentioned, for example, the power of being able to compositionally combine various commands through pipes, each of which doing one thing well. Inputs and outputs, remember? The post the author is responding to is uninformed, and seems rather like a rant. DOS vs UNIX comparison does not work. I couldn't know how to take the `apt-get` example seriously. Because you could easily fix something like `alias ai='sudo apt-get install'` to achieve `ai something` magic with something as simple as aliases, which DOS does not even provide.
