The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'.

You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_iot_dps_linked hub_create'.The syntax is: az iot dps linked-hub create --dps-name
                             [--allocation-weight]
                             [--apply-allocation-policy {false, true}]
                             [--connection-string]
                             [--hn]
                             [--hrg]

                             [--resource-group]. The 1th example of the child command would be to use it to 'create a linked iot hub in an azure iot hub device provisioning service instance', the syntax is: az iot dps linked-hub create --dps-name MyDps --resource-group MyResourceGroup --location westus --connection-string 'HostName=myhub.azure-devices.net;SharedAccessKeyName=iothubowner;SharedAccessKey=12345'. The 2th example of the child command would be to use it to 'create a linked iot hub in an azure iot hub device provisioning service which applies allocation weight and weight being 10', the syntax is: az iot dps linked-hub create --dps-name MyDps --resource-group MyResourceGroup --location westus --allocation-weight 10 --apply-allocation-policy True --connection-string 'HostName=myhub.azure-devices.net;SharedAccessKeyName=iothubowner;SharedAccessKey=12345'. The parameter '--dps-name' is required. It is used to iot hub device provisioning service name.. The parameter '--allocation-weight' is optional. allocation weight of the iot hub.. The parameter '--apply-allocation-policy' is optional. a boolean indicating whether to apply allocation policy to the iot hub.. The parameter '--connection-string' is optional. connection string of the iot hub. required if hub name is not provided using --hub-name.. The parameter '--hn --hub-name' is optional. iot hub name.. The parameter '--hrg --hub-resource-group' is optional. iot hub resource group name.. The parameter '--no-wait' is optional. do not wait for the long-running operation to finish.. The parameter '--resource-group -g' is optional. name of resource group. you can configure the default group using `az configure --defaults group=<name>`..
