csvlook/csvkit, apparently; something I never heard of before, which is actually not installed by default in ubuntu. He also included the data itself, which is pretty helpful, but which could have more usefully gone into a git repo somewhere.

Also "kids these days" all reach for docker. Otherwise any sane person would have just used cat instead of csvlook.

Upvoted the kid's article, because command line text cleaning is of TOWERING IMPORTANCE to any DS person worth their salt. But he is definitely an inexperienced kid.
