# update

## Syntax

```
update [<url>]
```

## Syntax Description

<table><thead><tr><th width="203">Keyword</th><th>Description</th></tr></thead><tbody><tr><td>url</td><td>The URL of the update file</td></tr></tbody></table>

## Defaults

If a URL is not specified, the most recent Island firmware update will be used. If the URL is a simple filename, the file is downloaded from the Island software distribution site.

## Usage Guidelines

This command loads new firmware or an installable software packge onto the Island.

The most common form of this command is to specify it without a URL. This will cause Island to look for a newer firmware version and, if found, download and install it.

## Examples

```
update
update pingurl
```
