>Then we'll agree to disagree. I think you are wrong on so many points here

Thanks for casting aspersions without even so much as a mention of what the "so many points" are that I am supposedly wrong on.

When I said upthread that you have misunderstandings, I at least mentioned some and hinted at or gave a clue to what the others were.

Also interesting that when kazinator said to you that awk is part of shell, you meekly accepted that he was right, thereby contradicting your earlier claim that my shell solution was not a shell but an awk solution. And in that same comment ( https://news.ycombinator.com/item?id=19279030 ) accepting it, you still seem to be neither here nor there, by your own words, where you say things like you "see why it could, perhaps should, be though (sic) of as being "shell", but "always have trouble thinking of it as such".
