I'm still pretty entrenched in "old school" iControl with the soap interface, but with Colin's new series on the iControl REST interface underway, I thought I'd start taking more than a glance.

This can be done with any number of bash, perl, python, and more tools, but I ran across one on twitter last night that is somewhat magical. jq is a single binary you can download and it just works. So why bother? Well, as Colin pointed out, the returned json data (by default) is none too fabulous in format:
