ofctl —

device tree
SYNOPSIS
ofctl |
[-lp] [-f
file] [-r
propfile] [-w
propfile] [node] |
DESCRIPTION
ofctl provides an interface for displaying the OpenPROM
or OpenFirmware device tree and node properties. The
ofctl program is only installed on supported
platforms.
Without any arguments, ofctl will dump the
full tree. When given the name of a specific node,
ofctl will display that node and its child
nodes.
The options are as follows:
-ffile- On systems with OpenPROM, use file instead of the default /dev/openprom. On systems with OpenFirmware, use file instead of the default /dev/openfirm.
-l- Dump a partial tree starting from node.
-p- Display each node's properties.
-rpropfile- Instead of reading from the openprom or openfirm device, use the proplib
file propfile as input. See also
-w. -wpropfile- Write the device tree to the proplib file propfile.
See also
-r.
