jq is like
sed for JSON data – you can use it to slice and filter
and map and transform structured data with the same ease that
grep and friends let you play with text.
jq is written in portable C, and it has zero runtime
dependencies. You can download a single binary,
scp it to a far away
machine, and expect it to work.
jq can mangle the data format that you have into the one that you
want with very little effort, and the program to do so is often
shorter and simpler than you’d expect.
