Converter JSON para CSV-BASH

Question

Arquivo JSON:

"UserDetailList": [
        {
            "UserName": "citrix-xendesktop-ec2-provisioning", 
            "GroupList": [], 
            "CreateDate": "2017-11-07T14:20:14Z", 
            "UserId": "1234556", 
            "Path": "/", 
            "AttachedManagedPolicies": [
                {
                    "PolicyName": "AmazonEC2FullAccess", 
                    "PolicyArn": "arn:aws:iam::aws:policy/AmazonEC2FullAccess"
                }, 
                {
                    "PolicyName": "AmazonS3FullAccess", 
                    "PolicyArn": "arn:aws:iam::aws:policy/AmazonS3FullAccess"
                }
            ], 
            "Arn": "arn:aws:iam::1234567890:user/citrix-xendesktop-ec2-provisioning"
        }, 
        {
            "UserName": "rundeck-read-only-iam-permissions", 
            "GroupList": [], 
            "CreateDate": "2018-03-09T11:13:38Z", 
            "UserId": "AIDAJQOQGKISLCWDXG6EQ", 
            "Path": "/", 
            "AttachedManagedPolicies": [
                {
                    "PolicyName": "IAMReadOnlyAccess", 
                    "PolicyArn": "arn:aws:iam::aws:policy/IAMReadOnlyAccess"
                }
            ], 
            "Arn": "arn:aws:iam::279052847476:user/rundeck-read-only-iam-permissions"
        }
    ], 

com jq -r '.UserDetailList[] | [.UserName] | @csv' output.json > fileout2.csv

Eu posso pegar

citrix-xendesktop-ec2-provisioning"
"rundeck-read-only-iam-permissions"

Como obter políticas do IAM para esses dois usuários, preciso extrair o AmazonEC2FullAccess e o AmazonS3FullAccess em AttachedManagedPolicies?

então a saída pode ser

citrix-xendesktop-ec2-provisioning",AmazonEC2FullAccess
citrix-xendesktop-ec2-provisioning",AmazonS3FullAccess
rundeck-read-only-iam-permissions,IAMReadOnlyAccess

    

Answer 1

funcionou: jq -r '.UserDetailList[] | .UserName as $u | .AttachedManagedPolicies[] | [$u, .PolicyName] | @csv' output.json > fileout.csv
