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

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
