AWS SSM get-parameter-by-path Manipulate JSON

Question

I am trying to retrieve all the parameters under a specific path from the AWS Parameter store using the command below:

aws ssm get-parameters-by-path --path some-path --no-paginate

This returns me a JSON with a lot of fields I do not need. How can I use the --query to just retrieve the name and the value?

Any documentation on how can I use the --query parameter? I have tried passing jq query strings, but that doesn't work.

You need to extract the fields from Parameters(Array) and later select the fields you want to get using {key:value} syntax:

aws ssm get-parameters-by-path --path %PATH% --no-paginate --region %REGION% --query "Parameters[].{Key:Name,Val:Value}" --output json

Output Json:

[
    {
        "Key": "/test/amit",
        "Val": "test1"
    },
    {
        "Key": "/test/amit1",
        "Val": "test2"
    }
]

Or in case you want the output in text, change --output to text.

Output Text:

/test/amit      test1
/test/amit1     test2
