USB_WAIT

The USB_WAIT command pauses until USB storage is attached.

Payloads which require USB storage can use this to wait until a USB drive is connected.

Options

By default, USB_WAIT controls the LED to indicate that it is waiting for input; by setting the NO_LED environment variable first, USB_WAIT can be told to leave the LED alone:

NO_LED=1 USB_WAIT

Experimenting

You can experiment using the USB_WAIT command live, either in the Web Shell in the web UI, or via ssh!

The terminal will pause until you cancel the command by pressing control-c or a USB storage device is attached.

Examples

Payloads can delay indefinitely until USB storage is attached using the USB_WAIT command.
