JSON to plain text using jq

Question

Let's say i got the following json response:

{
  "author": "tomek",
  "title": "helloworld",
  "test": "sampletextonetwothree"
}

Is it possible to display something like this: (using jq)

author=tomek
title=helloworld
test=sampletextonetwothree

Answer 1

jq 'to_entries[] | "\(.key)=\(.value)"'

should do it

Answer 2

Another way to join the values is to use string concatenation:

jq -r 'to_entries[] | .key + "=" + .value'
