udevadm expects a command and command specific options\. It controls the runtime behavior of udev, requests kernel events, manages the event queue, and provides simple debugging mechanisms\.

.PP
Queries the udev database for device information stored in the udev database\. It can also query the properties of a device from its sysfs representation to help creating udev rules that match this device\.

Do not trigger events for devices with a matching sysfs attribute\. If a value is specified along with the attribute name, the content of the attribute is matched against the given value using shell style pattern matching\. If no value is specified, the existence of the sysfs attribute is checked\. This option can be specified multiple times\.
