Hello,
Is there a direct command to check if the delimiter in your file is a tab or a space? And how can they be converted from one to another.
Thanks,

Hi,
I am writing a Perl Script for the below :

I can not make it work, it prints \t rather than introduce tabs.

acpibat
ACPIBAT(4) BSD Kernel Interfaces Manual ACPIBAT(4)NAME
acpibat -- ACPI Battery
SYNOPSIS
acpibat* at acpi?
DESCRIPTION
The acpibat driver supports ACPI batteries.
The battery status is made available through the envsys(4) API. The battery information can be displayed also with the envstat(8) command:
$ envstat -d acpibat0
Current CritMax WarnMax WarnMin CritMin Unit
present: ON
design voltage: 14.400 V
voltage: 16.267 V
design cap: 74.880 Wh
last full cap: 48.260 Wh
charge: 47.910 5.000% 0.414% Wh (99.27%)
charge rate: N/A
discharge rate: 16.641 W
charging: OFF
charge state: NORMAL
Depending on the battery, the unit of measurement is either watt-hour (Wh) or ampere-hour (Ah) for the capacity related information. From
these the ``charge'' is usually the most interesting value, but it is possible to derive useful information also from the other values. For
example, when acpiacad(4) is disconnected, the ``discharge rate'' gives a coarse approximation of the current power consumption. The ratio
between the design capacity and the last full capacity on the other hand reveals the overall ``health'' of deteriorating lithium-ion batter-
ies.
EVENTS
The acpibat driver is able to send events to powerd(8) daemon when a capacity state has been changed. The new state will be reported as the
fourth argument to the /etc/powerd/scripts/sensor_battery script. If a custom capacity limit was set via envstat(8), the acpibat driver will
report a user-capacity event to the same script when current capacity limit has been reached.
SEE ALSO acpi(4), envsys(4), envstat(8), powerd(8)HISTORY
The acpibat driver appeared in NetBSD 1.6.
BUGS
The ACPI specifications make a distinction between ``control method batteries'' and ``smart batteries''. The acpibat driver only supports
control method batteries. Furthermore, acpibat does not yet support some additional battery information introduced in the ACPI 4.0 standard.
