# Use `DescribeStep` with an AWS SDK or CLI
<a name="emr_example_emr_DescribeStep_section"></a>

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

Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code example:

#### [ CLI ]

**AWS CLI**  
The following command describes a step with the step ID `s-3LZC0QUT43AM` in a cluster with the cluster ID `j-3SD91U2E1L2QX`:  

```
aws emr describe-step --cluster-id j-3SD91U2E1L2QX --step-id s-3LZC0QUT43AM
```
Output:  

```
