I've been playing with jq, and I've been having a hard time finding examples of how it works with output from a service like AWS (which I use a lot).

Here is one I use a lot with vagrant-ec2.

When we're launching and killing a lot of instances, the AWS API is the only way to track down which instances are live, ready, dead, etc.

To find instances that are tagged with e.g. {"Key" = "Name", "Value" = "Web-00'} in the middle of a vagrant dev cycle, or a prod launch/replace cycle, you can do something like this:

a-c-t-i-n-i-u-m

#!/bin/bash
 
# settings
# Login information of freenom.com
freenom_email="main@address"
freenom_passwd="pswd"
# Open DNS management page in your browser.
# URL vs settings:
#   https://my.freenom.com/clientarea.php?managedns={freenom_domain_name}&domainid={freenom_domain_id}
freenom_domain_name="domain.name"
