Ubuntu – run bash commands from an Ubuntu HTML5 App

The trick is to use WebKit's remote inspector. Here's how I got it working in QtCreator 3.0:

• Download Google Chrome if you don't already have it. (I believe Safari also works.)
• In QtCreator, click "Projects" in the left column, then click the "Run" tab at the top.
• Next to "Run Environment", click the "Details" drop-down.
• Click "Add" to add a new environment variable.
• Set a variable named QTWEBKIT_INSPECTOR_SERVER and set the value to any unused local port number, for example 9999
• Run your project
• Open Chrome and enter the following URL: http://127.0.0.1:9999

It may take a moment to come up. If the URL isn't working you can use a tool like Microsoft TCPView (on Windows) to make sure your process has the port open.
