**To update a CloudFront distribution**

The following command updates the Default Root Object to "index.html"
for a CloudFront distribution with the ID ``S11A16G5KZMEQD``::

  aws cloudfront update-distribution --id S11A16G5KZMEQD \
    --default-root-object index.html

The following command disables a CloudFront distribution with the ID ``S11A16G5KZMEQD``::

  aws cloudfront update-distribution --id S11A16G5KZMEQD --distribution-config file://distconfig-disabled.json --if-match E37HOT42DHPVYH

The distribution ID is available in the output of ``create-distribution`` and ``list-distributions``. The ETag value ``E37HOT42DHPVYH`` for the ``if-match`` parameter is available in the output of ``create-distribution``, ``get-distribution`` or ``get-distribution-config``.

The file ``distconfig-disabled.json`` is a JSON document in the current folder that modifies the existing distribution config for ``S11A16G5KZMEQD`` to disable the distribution. This file was created by taking the existing config from the ``DistributionConfig`` key in the output of ``get-distribution-config`` and changing the ``Enabled`` key's value to ``false``::

After disabling a CloudFront distribution you can delete it with ``delete-distribution``.

The output includes the updated distribution config. Note that the ``ETag`` value has also changed::
