That particular example actually says nothing against you, and certainly doesn't mean the Unix tools are hostile, as the neighbor comment says. The ‘grep|wc’ flow is natural in the Unix paradigm, because each command does its own thing there—it's exactly like functional programming. The ‘grep -c’ thing is a shortcut that may be an optimization but doesn't conform to the ideals.

I don't know if it's easier for humans to remember one command with flags or two commands, but it's certainly best to recognize the principles and learn to use them, which is what the ‘grep|wc’ case demonstrates.
