NAME
       udevinfo - query device information from the udev database

SYNOPSIS
       udevinfo [--query=query-type] [--path=devpath] [--name=node] [--root]
		[--attribute-walk] [--export-db] [--version] [--help]

DESCRIPTION
       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
       device.

OPTIONS
       --query=type
	   Query the database for specified type of device data. It needs the
	   --path or --name to identify the specified device. Valid queries
	   are: name, symlink, path, env, all.

       --path=devpath
	   The devpath of the device to query.

       --name=node
	   The name of the device node or a symlink to query

       --root
	   The udev root directory: /dev. If used in conjunction with a name
	   or symlink query, the query returns the absolute path including the
	   root directory.

       --attribute-walk
	   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.

       --export
	   Export the content of the udev database.

       --help
	   Print help text.
