OFCTL(8) BSD System Manager's Manual OFCTL(8)NAME
ofctl -- display the OpenPROM or OpenFirmware device tree
SYNOPSIS
ofctl [-p] [-f file] [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.
-p Display each node's properties.
FILES
/dev/openprom The openprom device on systems with OpenPROM.
/dev/openfirm The openfirm device on systems with OpenFirmware.

SIMPLEBUS(4) BSD Kernel Interfaces Manual SIMPLEBUS(4)NAME
simplebus -- ePAPR simple-bus driver
SYNOPSIS
options FDT
DESCRIPTION
This bus driver is dedicated for the simple-bus node of a flattened device tree compliant with the ePAPR specification.
The simplebus entity does not represent any physical element by itself, it is rather an umbrella node grouping integrated on-chip peripherals
like interrupt controller, connectivity controllers, accelerating engines and so on.
The driver is generic and common for all flattened device tree nodes claiming simple-bus compatibility. It iterates over direct descendants
of the simple-bus node, instantiates newbus children and assigns resources to them, based on the configuration data retrieved from the nodes
properties in fdt(4).
Note the simplebus does not manage device resources and passes through any requests to the fdtbus(4) layer.

HISTORY
The simplebus support first appeared in FreeBSD 9.0.
AUTHORS
The simplebus support was developed by Semihalf under sponsorship from the FreeBSD Foundation. This manual page was written by Rafal

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:
$ ls -ld /usr/bin /usr/bin/cat
drwxrwxr-x 3 root bin 8704 Sep 23 2004 /usr/bin

and would like to sort it numerically on the first field. I tried:
sort -nr --key=1 ....
The output I get is:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I'm trying to install a PGX32 video card on my Sparc 10 Ultra running Solaris 10.

Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.
The prompt is... (2 Replies)
Hey gang, I have a list of times I need to sum up. This list can vary from a few to a few thousand entries.

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
But what a book. The one I found and ordered is BSD Unix®... (0 Replies)
