Examples

To update a thing shadow

The following update-thing-shadow example modifies the current state of the device shadow for the specified thing and saves it to the file output.txt.

aws iot-data update-thing-shadow \
    --thing-name MyRPi \
    --payload "{"state":{"reported":{"moisture":"okay"}}}" \
    "output.txt"

The command produces no output on the display, but the following shows the contents of output.txt:

{
    "state": {
        "reported": {
            "moisture": "okay"
        }
    },
    "metadata": {
        "reported": {
            "moisture": {
                "timestamp": 1560270036
            }
        }
    },
    "version": 2,
    "timestamp": 1560270036
}
