It needs the -p or -n to identify the specified device. Valid queries are: name, symlink, path, env, all. -a Print all sysfs properties of the specified device that can be used in udev rules to match the specified device. It prints all devices along the chain, up to the root of sysfs that can be used in udev rules. -p device-path The sysfs path of the device to query. -n node-name The name of the device node or a symlink to query -r The udev root directory: /dev. If used in conjunction with a name or symlink query, the query returns the absolute path. -e Export the content of the udev database. -h Print help text.
