OFWDUMP(8) 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 op- tion, 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 avail- able properties: ofwdump -pr /pci Print the "compatible" property of the "/pci" node as plain string: ofwdump -P compatible -S /pci SEE ALSO eeprom(8) HISTORY The ofwdump utility first appeared in FreeBSD 5.0.
