**To update a CloudFront distribution**

The following example disables the CloudFront distribution with the ID
``EMLARXS9EXAMPLE`` by providing the distribution configuration in a JSON file
named ``dist-config-disable.json``. To update a distribution, you must use the
``--if-match`` option to provide the distribution's ``ETag``. To get the
``ETag``, use the `get-distribution <get-distribution.html>`_ or
`get-distribution-config <get-distribution-config.html>`_ command.

After you use the following example to disable a distribution, you can use the
`delete-distribution <delete-distribution.html>`_ command to delete it.

::

    aws cloudfront update-distribution \
        --id EMLARXS9EXAMPLE \
        --if-match E2QWRUHEXAMPLE \
        --distribution-config file://dist-config-disable.json

The file ``dist-config-disable.json`` is a JSON document in the current folder
that contains the following. Note that the ``Enabled`` field is set to
``false``::
