–output=text will print everything within innermost [] brackets on single line..

To see it in action see the difference between

1
aws iam list-users --query Users[*].[UserName]

1
aws iam list-users --query [Users[*].UserName]

For nested list object, instead of [*] use [0](individual item) for single line output. Like here for CacheClusters[].CacheNodes

To see it in action see the difference between

1
aws elasticache describe-cache-clusters   --show-cache-node-info --query CacheClusters[].[CacheClusterId,CacheNodes[0].Endpoint.Address] --output table

1
aws elasticache describe-cache-clusters   --show-cache-node-info --query CacheClusters[].[CacheClusterId,CacheNodes[].Endpoint.Address] --output table
