# NAME

`ofctl` —
display the OpenPROM or OpenFirmware device tree

# SYNOPSIS

`ofctl` | [`-lpv`] [`-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:

`-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`.
`-v`
  Display the full path name for each node.
`-w` propfile
  Write the device tree to the proplib file propfile. See also `-r`.

# FILES

/dev/openprom
  The openprom device on systems with OpenPROM.
