+# Script: system-usb-udev
+
+A small script that shows your mounted and not mounted removable devices. This is an extended version of [system-usb-mount](../system-usb-mount).
+
+Click left to mount all removable devices. Click right to unmount the devices. The removable devices are then turned off with `udisksctl power-off`.
+
+The mount option has a feature: You can also start a file manager and open the device when you mount it. Look at the example in the code: `terminal -e "bash -lc 'filemanager $mountpoint'" &`
+
+This script is able to display device changes in real time. For this udev is being used.
