<a name="mediapackage_example_mediapackage_ListChannels_section"></a>

The following code examples show how to use `ListChannels`.

------
#### [ CLI ]

**AWS CLI**  
**To list all channels**  
The following `list-channels` command lists all of the channels that are configured on the current AWS account.  

```
aws mediapackage list-channels
```
Output:  

```
{
    "Channels": [
        {
            "Arn": "arn:aws:mediapackage:us-west-2:111222333:channels/584797f1740548c389a273585dd22a63",
            "HlsIngest": {
                "IngestEndpoints": [

 There's more on GitHub. Find the complete example and learn how to set up and run in the [AWS Code Examples Repository](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/rustv1/examples/mediapackage#code-examples). 
List channel ARNs and descriptions.  

```
async fn show_channels(client: &Client) -> Result<(), Error> {
    let list_channels = client.list_channels().send().await?;

    println!("Channels:");

    for c in list_channels.channels() {
        let description = c.description().unwrap_or_default();
        let arn = c.arn().unwrap_or_default();

        println!("  Description : {}", description);
        println!("  ARN :         {}", arn);
        println!();
    }

    Ok(())
}
