Create json with a string variable as argument using jq

Question

I'm trying to create a json file using a variable somewhat like this:

input:

ss="mango"
jq -n '{"name": {"S": $ID}}' --arg ID 'partridge in a $ss tree'

actual output:

{
  "name": {
    "S": "partridge in a $ss tree"
  }
}

expected output:

{
  "name": {
    "S": "partridge in a mango tree"
  }
}

Is there a way to achieve this using jq?

Answer 1

Try --arg ID "value" in double quote like following:

ss="mango"
jq -n '{"name": {"S": $ID}}' --arg ID "partridge in a $ss tree"

---

output:

{
  "name": {
    "S": "partridge in a mango tree"
  }
}
