Neat! I love single purpose shell utilities composes with other commands (“do one thing well”). I like that this also plays nicely with jq, which is one of my favorite tools.

For me, small, standalone binaries like this are where golang shines brightest. I created a cmdline tool called ganda (https://github.com/tednaleid/ganda) that can take thousands of piped urls and it’ll download them all in parallel and pipe the results on stdout to something like jq (or save to a file). I think the json output of tj might fit well with this, I’ll give it a shot.
