UDEVINFO(8)			   udevinfo			   UDEVINFO(8)

NAME
       udevinfo - query device information from the udev database

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

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
       -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.
