= Updating subscriptions by using the Knative CLI
|
|
|
|
You can use the `kn subscription update` command as well as the appropriate flags to update a subscription from the terminal by using the Knative (`kn`) CLI. Using the Knative CLI to update subscriptions provides a more streamlined and intuitive user interface than updating YAML files directly.

|

* You have installed the Knative (`kn`) CLI.
|
|
* You have created a subscription.
|

<1> `--sink` specifies the updated target destination to which the event should be delivered. You can specify the type of the sink by using one of the following prefixes:
|
|
`ksvc`:: A Knative service.
|
|
`channel`:: A channel that should be used as destination. Only default channel types can be referenced here.
|
|
`broker`:: An Eventing broker.
|
|
<2> Optional: `--sink-dead-letter` is an optional flag that can be used to specify a sink which events should be sent to in cases where events fail to be delivered. For more information, see the {ServerlessProductName} _Event delivery_ documentation.
