BATTERY_PMU(4) BSD Kernel Interfaces Manual BATTERY_PMU(4)NAME
battery_pmu -- support for batteries and sensors in PCI-based Apple Powerbooks
SYNOPSIS
battery* at pmu?
DESCRIPTION
The battery_pmu driver provides support for batteries and hardware sensors found in first generation PCI-based PowerBooks (i.e. Apple Power-
book 2400, 3400 and 3500 (also known as Original PowerBook G3). Currently it only exports a few sensors via the envsys(4) interface, includ-
ing battery charge, voltage, CPU and battery temperature and AC power availability.
SEE ALSO envsys(4), pmu(4), envstat(8)BUGS
There is no APM emulation right now and the battery current sensor may return misleading or wrong data. This driver is considered prelimi-
nary and may be replaced at some point.

IPMI(4) BSD Kernel Interfaces Manual IPMI(4)NAME
ipmi -- Intelligent Platform Management Interface driver
SYNOPSIS
ipmi0 at mainbus?
DESCRIPTION
The ipmi device driver supports motherboards implementing the Intelligent Platform Management Interface version 1.5 or 2.0, and exports sen-
sors and the watchdog through the envsys(4) interface.
EVENTS
The ipmi driver is able to send events to powerd(8) when a sensor's state has changed. Intrusion sensors will send a critical event when
state is not ok. Power Supply sensors will send a critical event when the Power Supply unit is not installed and warning-over when the Power
Supply unit is installed but not powered on. Fan, temperature and voltage sensors will send critical-over or critical-under when the value
is very critical, or warning-over or warning-under if it's in a warning alert.
SEE ALSO envsys(4), envstat(8), powerd(8), wdogctl(8)HISTORY
The ipmi driver first appeared in OpenBSD 3.9 and was then ported to NetBSD 4.0.
AUTHORS
The ipmi driver was originally written by Jordan Hargrave and was ported to NetBSD by Manuel Bouyer <bouyer@NetBSD.org>.

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:

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)

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 ;)
