**Note**  
These steps do not apply to nucleus lite.

The Greengrass CLI can take up to a minute to deploy. Run the following command to check the status of the deployment. Replace {{MyGreengrassCore}} with the name of your core device.

```
aws greengrassv2 list-effective-deployments --core-device-thing-name {{MyGreengrassCore}}
```

The `coreDeviceExecutionStatus` indicates the status of the deployment to the core device. When the status is `SUCCEEDED`, run the following command to verify that the Greengrass CLI is installed and runs. Replace `{{/greengrass/v2}}` with the path to the root folder.

------
#### [ Linux or Unix ]

```
{{/greengrass/v2}}/bin/greengrass-cli help
```

------
#### [ Windows Command Prompt (CMD) ]

```
{{C:\greengrass\v2}}\bin\greengrass-cli help
```

------
#### [ PowerShell ]

```
{{C:\greengrass\v2}}\bin\greengrass-cli help
```

------

The command outputs help information for the Greengrass CLI. If the `greengrass-cli` isn't found, the deployment might have failed to install the Greengrass CLI. For more information, see [Troubleshooting Amazon IoT Greengrass V2](troubleshooting.md).

You can also run the following command to manually deploy the Amazon IoT Greengrass CLI to your device.
+ Replace {{region}} with the Amazon Web Services Region that you use. Make sure that you use the same Amazon Web Services Region that you used to configure the Amazon CLI on your device.
+ Replace {{account-id}} with your Amazon Web Services account ID.
+ Replace {{MyGreengrassCore}} with the name of your core device.

------
#### [ Linux, macOS, or Unix ]

```
aws greengrassv2 create-deployment \
  --target-arn "arn:aws-cn:iot:{{region}}:{{account-id}}:thing/{{MyGreengrassCore}}" \
  --components '{
    "aws.greengrass.Cli": {
      "componentVersion": "2.18.0"
    }
  }'
```

------
#### [ Windows Command Prompt (CMD) ]

```
aws greengrassv2 create-deployment ^
  --target-arn "arn:aws-cn:iot:{{region}}:{{account-id}}:thing/{{MyGreengrassCore}}" ^
  --components "{\"aws.greengrass.Cli\":{\"componentVersion\":\"2.18.0\"}}"
```

------
#### [ PowerShell ]

```
aws greengrassv2 create-deployment `
  --target-arn "arn:aws-cn:iot:{{region}}:{{account-id}}:thing/{{MyGreengrassCore}}" `
  --components '{\"aws.greengrass.Cli\":{\"componentVersion\":\"2.18.0\"}}'
```

**Tip**  
You can add `{{{{/greengrass/v2}}}}/bin` (Linux) or `{{{{C:\greengrass\v2}}}}\bin` (Windows) to your `PATH` environment variable to run `greengrass-cli` without its absolute path.
