Re: Head to head
You keep parrotting the argument that "you have to use the command line", which has all the hallmarks of superstition about it; as though somehow there was something wrong with that.
Seriously, what is so bad about the command line?
For me, the command line is simply a way of issuing a precise command straight to the computer, in a way that does not depend on the user's personal configuration options. In answering a question asked by a user, I can write "Open a terminal window and paste in the following:" and be confident that it will Just Work.
If I had to describe the process of clicking through various icons and menus, it probably would break if the user had altered their configuration from the default as shipped. It would also take a lot longer to describe the process.
Why do you think there is a difference between entering a quick textual command without making any pretence of understanding it, and making a long series of mouse clicks without making any pretence of understanding it?
