**To update a function alias**

The following ``update-alias`` example updates the alias named ``LIVE`` to point to version 3 of the ``my-function`` Lambda function. ::

    aws lambda update-alias \
        --function-name my-function \
        --function-version 3 \
        --name LIVE

Output::

    {
        "FunctionVersion": "3",
        "Name": "LIVE",
        "AliasArn": "arn:aws:lambda:us-west-2:123456789012:function:my-function:LIVE",
        "RevisionId": "594f41fb-b85f-4c20-95c7-6ca5f2a92c93",
        "Description": "alias for live version of function"
    }
