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 SEE ALSO

If both the property and device object exists the value of the property is printed on stdout and the program will exit with exit code 0. Otherwise the exit code will be non-zero. BUGS
