How to convert a JSON object to key=value format in jq?

Question

In jq, how can I convert a JSON to a string with key=value?

From:

{     "var": 1,     "foo": "bar",     "x": "test" } 

To:

var=1 foo=bar x=test

You could try:

jq -r 'to_entries|map("\(.key)=\(.value|tostring)")|.[]' test.json 

Here's a demo:

$ cat test.json {     "var": 1,     "foo": "bar",     "x": "test" } $ jq -r 'to_entries|map("\(.key)=\(.value|tostring)")|.[]' test.json foo=bar var=1 x=test
