使用Shell脚本解析JSON

Question

I need to parse JSON using shell script (I used to use Python, but not allowed in this specific environment), in this example, I want to get the value of b1 , which is 6.5 , anyone have any experience?

Using Linux/Mac OSX.

{
    "value": {
        "a1": {
            "amount": "5.5",
            "currency": "USD"
        },
        "b1": {
            "amount": "6.5",
            "currency": "USD"
        },
        "c1": {
            "d1": {
                "amount": "7.5",
                "currency": "USD"
            },
            "e1": {
                "amount": "8.5",
                "currency": "USD"
            },
            "f1": {
                "amount": "9.5",
                "currency": "USD"
            }
        },
        "g1": {
            "amount": "10.5",
            "currency": "USD"
        },
    }
}

Use jsawk:

bash jsawk < /tmp/my_data.json 'return this.value.b1.amount'
