That's the idea :)

Now, "parsing" JSON this way feels super fragile. If you have to stick
to shell, I recommend using jq(1) to extract the info you want.

But really, switching to Python / Ruby / etc. would be nicer (and then
you won't have to deal with the "shell programming is hard" problem,
which your example script shows — e.g. missing quotes may lead to
arbitrary code execution as root on all your users' systems, if our
latest.json ever had malicious content).

Cheers,
