Given a file path, unplug the USB device on which the file is located (the file must be on an USB device !)

You have an external USB drive or key.

Apply this command (using the file path of anything on your device) and it will simulate the unplug of this device.

If you just want the port, just type :

echo $(sudo lshw -businfo | grep -B 1 -m 1 $(df "/path/to/file" | tail -1 | awk '{print $1}' | cut -c 6-8) | head -n 1 | awk '{print $1}' | cut -c 5- | tr ":" "-")

Create random password in reasonable time

It will produce passwords with length of 20 printable characters within a reasonable time.

To create only alpha numeric passwords change [:print:] to [:alnum:]
