using jq how to sort array of object

Question

There is an array of json object, using jq how to check if an object exists if so returns the true else false

I tried this but getting error

cat fruits.json | jq '.fruits[]| sort_by(.version)'

I would like to sort by decending order and output the price of the most recent version.

{
    "fruits": [
        {
            "name": "banana",
            "color": "yellow",
            "price": 0.51,
           "version": 1
        },
        {
            "name": "banana",
            "color": "yellow",
            "price": 0.52,
            "version": 2
        }
    ]
}

Something like `cat fruits.json | jq '.fruits| sort_by(-.version) | first'`? Or am I misunderstanding? — Joachim Isaksson, Dec 27 '21 at 08:03

cat fruits.json | jq '.fruits | sort_by(-.version)[0].price'

produces:

0.52

You need try like:

.fruits |= sort_by(.version)

Reference sort by keys
