OFWDUMP(8)		FreeBSD	System Manager's Manual		    OFWDUMP(8)

NAME
     ofwdump --	examine	the Open Firmware device tree

SYNOPSIS
     ofwdump -a	[-p | -P property] [-R | -S]
     ofwdump [-p | -P property]	[-r] [-R | -S] [--] nodes

DESCRIPTION
     The ofwdump utility is used to examine the	Open Firmware device tree.  In
     the first synopsis	form, the complete device tree is printed; in the sec-
     ond form, only the	selected nodes will be examined.

     The following options are available:

     -a		  Print	the complete device tree.

     -p		  Print	all available properties.

     -P	property  Only print properties	of the given name.

     -R		  Print	properties in ``raw'' format, i.e., omit all headings
		  and indentation and just write the property values unaltered
		  to the standard output.  This	is intended to be used with
		  the -P option	to extract the value of	a single property.

     -S		  Print	properties as strings; this is analogous to the	-R
		  option, except that each property is only output to the
		  first	NUL character, and that	newline	is appended to each.

     -r		  Recursively print all	children of the	specified nodes.

EXAMPLES
     Print the complete	device tree:

	   ofwdump -a

     Print the complete	device subtree of the ``/pci'' node, including all
     available properties:

	   ofwdump -pr /pci

     Print the ``compatible'' property of the ``/pci'' node as plain string:

	   ofwdump -P compatible -S /pci
