AWS CLI Command Line: How to use "--query" to output multiple source lines
aws ec2 describe-instances --instance-id i-77777777 \
--query 'Reservations[*].Instances[*].[InstanceId,ImageId,Tags[*]]' \
--output text
This command will print Instance Id, AMI ID, Key and Value Tags. You can see more examples here: Controlling Command Output from the AWS Command Line Interface
With Windows (cmd.exe, cmder.exe, etc.), one must use double quotes (") instead of single quotes (') around the query string. Otherwise the console simply prints the path in the query and doesn't even generate an error.
