Output

You can also get a preview of the output of a command by calling the command with the --generate-cli-skeleton output option. This can speed up the process of combining CLI commands as you can see a response without actually calling the API:

$ aws ec2 describe-availability-zones --generate-cli-skeleton output 
{ 
"AvailabilityZones": [ 
        { 
"ZoneName": "ZoneName", 
"State": "State", 
"RegionName": "RegionName", 
"Messages": [ 
                  { 
"Message": "Message" 
                } 
            ] 
        } 
    ] 
}
