# Google Domains DDNS Updater

Works well with `bash`.

This script follows the [LSBInitScripts](https://wiki.debian.org/LSBInitScripts/).

You can update your IP address every few minutes using `cron`, or update it at boot time using `init`.

## Installation

*Make your [host information file](#example-of-host-information-file) first.*

`init`:

```bash

# Update IP at runlevel 0 1 2 3 4 5 6 (while booting, rebooting, shutdown, etc.)

$ update-rc.d update-ddns start 90 2 3 4 5 . stop 90 0 1 6 .

```

`cron`:

```bash

$ crontab -e

# Update IP for every 5 mins

*/5 *    *   *   *   /etc/init.d/update-ddns start

```

## Example of host information file

```json

{

	"amount": 3,

	"host1":
