       udevinfo [-q query_type -p sysfs_path] [-drVh]

DESCRIPTION
       udevinfo	 allows	 users	to query the udev database for information on
       any device currently present on the system.  It also provides a way to
       query any device in the sysfs tree to help creating udev rules.

OPTIONS
       -V     Print the version information.

       -r     Print  the udev_root directory. When used in conjunction with a
	      query for the node name, the udev_root will be prepended.

       -q query_type
	      Query the database for specified value of a created device node
	      or network interface.  Needs -p or -n specified.
	      Valid  types  are: name, symlink, mode ,owner , group , path or
	      all.

       -p sysfs_path
	      Specify the sysfs path of the device to query.

       -n name
	      Specify the name of the node, the symlink or the network inter-
	      face  for	 the  device to query. Partition names generated with
	      the NAME{all_partitons} option can not  be  queried,  the	 main
	      device must be used instead.

       -a     Print  all  SYSFS{filename}  attributes along the device chain.
	      Useful for finding unique attributes to compose a rule.	Needs
	      -p specified.
