【jq】bashでjson配列をループさせる

jqの-cオプションを使うことで、シンプルにループ処理が可能。

--compact-output / -c:
By default, jq pretty-prints JSON output. Using this option will result in more compact output by instead putting each JSON object on a single line.

array.json

$ JSON='
[
    {
        "name": "JSON",
        "good": true
    },
    {
        "name": "XML",
        "good": false
    }
]
'

IFS=$'\n'; for item in $(echo $JSON | jq -c '.[]'); do
  echo $item | jq .name
done

# "JSON"
# "XML"
