       udevinfo - query device information from the udev database


       udevinfo [-q query-type] [-a ] [-p device-path] [-n node-name] [-r]
                [-e] [-V] [-h]


       udevinfo 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


       -q     Query the database for specified type of device data. 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.
