[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:
-
-
- -f
file
- 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.
-
-
- -r
propfile
- Instead of reading from the openprom or openfirm device,
use the proplib file propfile as input. See also
-w.
-
-
- -w
propfile
- Write the device tree to the proplib file
propfile. See also -r.
