dig-pretty

Make dig's output prettier. A very basic Python script that reformats the YAML output of dig into a more human-readable format. Requires a relatively new version of dig (new enough to support the +yaml option).

Mostly intended as a proof of concept to show that dig could have a more human-friendly output format, because I don't know enough C to try to contribute a different output format to dig.

installation

You'll need Python 3 and pyyaml installed.

pip install pyyaml

Then put it in your PATH somewhere

usage

You can pass any argument to it that dig supports. It'll just pass all the options through.

dig-pretty example.com
dig-pretty +norecurse example.com
dig-pretty @8.8.8.8 example.com

example output

$ dig-pretty example.com

Compare this to the dig output for the same query:

$ dig example.com
; <<>> DiG 9.10.6 <<>> +all example.com
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 5151

(dig-pretty leaves out the query timing information and message size because I've never used that information and it's not part of the DNS record itself)

why not dog?

The goal of dig-pretty is show that you can have the power of dig (all of the same options, and all of the same details in the output), but clearer formatting.

Tools like dog or doggo are great but they don't support all the options dig does, like +norecurse.

I think older tools like dig deserve nice formatting too :)

contributing

I don't necessarily plan to maintain this long term or add a lot of features but bug fixes are welcome!
