Using Unix utilities is so underrated. I love Unix programming for the simplicity and power that you demonstrate well here. It's not as flashy and cool as writing some big program but I am constantly amazed how people can go through new web framework fads every 2 months but these 40-50 year old programs are still the most useful tools around.
