OFWDUMP(8) BSD 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 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
