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 second 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 char-
		  acter, 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
