Here's a JS script [1] I wrote a little while ago just for my own use that queries the CDC for the latest virus numbers, then calcs the average, formats the data and prints to the command line. You can pass in a number of days, otherwise it pulls the last 14 days.

$ node query-cdc.js 7

It's nothing special, but I wouldn't want to try to do this with command line utilities. (And yes, it was a bit uglier, but I cleaned it up of random crap I had thrown in before posting it.)

There are plenty of CLI tools built on Node: https://github.com/sindresorhus/awesome-nodejs#command-line-...
