Create JSON with jq

I am trying to create a JSON file with jq from the result of the command "lsb_release"

What i have done :

if [ -x "$(command -v lsb_release)" ]; then
    lsb_release -a  | jq  --raw-input 'split("\t") | { (.[0]) : .[1] }' > ubuntu_release.json
fi

the result is

{
  "Distributor ID:": "Ubuntu"
}

{
  "Description:": "Ubuntu 20.04.3 LTS"
}

{
  "Release:": "20.04"
}

{
  "Codename:": "focal"
}

but i want the result

[
    {
      "Distributor ID:": "Ubuntu"
    },
    {
      "Description:": "Ubuntu 20.04.3 LTS"
    },
    {
      "Release:": "20.04"
    },
    {
      "Codename:": "focal"
    }
]

can anybody body help me ? 🙂

>Solution :

Usually, when we want to create an array from a stream of inputs, we can use --slurp/-s. But when combined with --raw-input/-R, this causes the entire input to be provided as a single string (that contains line feeds).

Slurping can also be achieved using --null-input/-n and [ inputs | ... ]. And this works as desired for text files.

jq  -nR '[ inputs | split("\t") | { (.[0]) : .[1] } ]'
