I was interested in reading multiple values from a JSON file and I have found out how to do this easily.
Just use jq like this.
curl -s https://www.news.com.au/wp-json/wp/v2/posts/ | jq -r '.[] | .title,.excerpt,.link' |
This will allow the reading of multiple values from a JSON file.
The result is shown below.

And another example.

This shows how easy it is to read JSON and parse multiple values.
To output the JSON data in plain text, one entry per line, you can use the -r or --raw option with jq. By using the -r option, jq will output the raw text of the selected fields, and we’re also using \n to add newline characters between each field, so each entry will be on a separate line. This will give you the output in plain text with one entry per line.

But a simpler way is to just do it like this.
(jcartwright@localhost) 192.168.1.5 ~ $ curl -s https://www.news.com.au/wp-json/api/weather/2000 | jq -r '.metadata' { "sector": "weather", "title": "Weatherzone", "provider_name": "Weatherzone", "provider_url": "http://www.weatherzone.com.au", "project_version": "5.04", "revision": 30518, "last_commit": "2023-06-22 15:16:00 +1000 (Thu, 22 Jun 2023)", "create_time": "2023-10-25T08:18:25+1100", "create_tz": "AEDT", "create_time_utc": "2023-10-24T21:18:25Z", "validity": "2023-10-25" } |
This shows how easy this is. Parsing JSON can be annoying at times, but this should help out a bit.
