It's cool to see this written in shell in a "that's clever" kind of way, but it's still not a good idea. Shell is good at gluing together calls to standard too

It's cool to see this written in shell in a "that's clever" kind of way, but it's still not a good idea. Shell is good at gluing together calls to standard tools, and for interactive use, but anything this complex is a much better fit for something like python. axiolite points out some apparent escaping bugs (https://news.ycombinator.com/item?id=27250215 https://news.ycombinator.com/item?id=27250215), which would be much easier to catch/fix in a language that was less of a Turing tarpit.
