Hi Neo,

basically it boils down to jq. Without it I never would have considered doing this task with bash. All JSON-Handling is done with jq. Bash is the code around it.

Even I may have considered differently after having it done, because the task got a little more complex than expected, I think I got the task done very quickly. It's working more than sufficiently well, the code is maintainable and the speed is acceptable. For smaller tasks I consider this still as an excellent choice.

Example: Get an ipaddress from zone data

Assuming this zone data...

JSON-Zonedata from PowerDNS-API . GitHub

...this would be the command to extract the pure ip address of the A-Record "ftp.bla.com":

Code:
jq -r '.rrsets[] | select(.name=="ftp.bla.com." and .type=="A") | .records[0].content '  <<<"$json"

#output

1.2.3.5
