Thanks Jim. I was thinking it might be as difficult as you say. When I've posted the complete situation over the past few days, I get responses that suggest I should not want to know this or do this. As an enthusiast I like to explore and learn, so thought I would try to ask a much more direct technical question to avoid being scolded. :-)
Attached are several of my posts from a more thorough thread I started last week that might answer any questions you have. Sorry it is so long.
I've had these similar data errors on a MacBook 2006 10.6.8, a MacBook 2010 10.8.x, and a two week old MacBook Pro 10.10.5. The older ones have been cleaned up with install of OS. Because of our hack history here I was trying to learn more about this.
The purpose of those comands are to find the newest file in a directory acvrdind to system date, and it has to be recursively found in each directory.
The problem is that i want to list in a long format every found file, but the commands i use produce unexpected results ,so the output lists in a... (5 Replies)
Hi ,
I have a typical situation. I have 4 files and with different headers (number of headers is varible ).
I need to make such a merged file which will have headers combined from all files (comman coluns should appear once only).
For example -
File 1
H1|H2|H3|H4
11|12|13|14
21|22|23|23... (1 Reply)
I have to find the specific formatted file is present in the received list in the directory, for which I have written:
file_list=`ls -lrt /tmp/vinay/act/files |grep "$cdate"| awk '{print $9}'`
while read fileStr
do
find $file_list $fileStr > /dev/null
status=`echo $?`
if ; then

Hi All,
We are copying all the files into ARCHIVE directory after we process them. We are doing this process from last 2 years, now we have a lot of files in ARCHIVE directory.
Now I need to find when the first file is copied into this directory?
If I Issue,

I have an issue with a korn shell script that I am writing. The script parses through a configuration file which lists a heap of path/directories for some files which need to be FTP'd. Now the script needs to check whether there are any files which have not been processed and are X minutes old.

Hi ,
I have a .txt file in which I have multiple headers, the header record starts with $ symbol...like the first column name is $Account.
I have to keep the header in the first line and delete all the remaining headers which are in the file.
I tried using sort adc.txt | uniq -u , but my... (7 Replies)
Hi I need to merge 4 files. The issue i am facing is all the files have headers and i do not want them in the final output file. Can anybody suggest how to do it? (5 Replies)
Hi All,
In the file names we have dates.
Based on the file format given by the user,
if any file is not existed for a particular date with in a given interval we should consider that file is missing.
I have the below files in the directory /bin/daily/voda_files.

atp
ATP(4) BSD Kernel Interfaces Manual ATP(4)NAME
atp -- Apple touchpad driver
SYNOPSIS
To compile this driver into the kernel, place the following lines into your kernel configuration file:
device atp
device usb
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
atp_load="YES"
DESCRIPTION
The atp driver provides support for the Apple Internal Trackpad device found in many Apple laptops. Older (Fountain/Geyser) and the newer
(Wellspring) trackpad families are all supported through a unified driver.
The driver simulates a three-button mouse using multi-finger tap detection. Single finger tap generates a left-button click; two-finger tap
maps to the middle button; whereas a three-finger tap gets treated as a right button click.
There is support for 2-finger horizontal scrolling, which translates to page-back/forward events; vertical multi-finger scrolling emulates
the mouse wheel.
A double-tap followed by a drag is treated as a selection gesture; a virtual left-button click is assumed for the lifespan of the drag.
atp supports dynamic reconfiguration using sysctl(8); through nodes under hw.usb.atp. Pointer sensitivity can be controlled using the sysctl
tunable hw.usb.atp.scale_factor. Smaller values of scale_factor result in faster movement. A simple high-pass filter is used to reduce con-
tributions from small movements; the threshold for this filter may be controlled by hw.usb.atp.small_movement. The maximum tolerable dura-
tion of a touch gesture is controlled by hw.usb.atp.touch_timeout (in microseconds); beyond this period, touches are considered to be slides.
(This conversion also happens when a finger stroke accumulates at least hw.usb.atp.slide_min_movement movement (in mickeys). The maximum
time (in microseconds) to allow an association between a double- tap and drag gesture may be controlled by hw.usb.atp.double_tap_threshold.
Should one want to disable tap detection and rely only upon physical button presses, set the following sysctl to a value of 2
hw.usb.atp.tap_minimum.

To discover the product-id of a touchpad, search for 'Trackpad' in the output of lshal(1) and look up the property usb_device.product_id.
FILES
atp creates a blocking pseudo-device file, /dev/atp0, which presents the mouse as a sysmouse or mousesystems type device--see moused(8) for
an explanation of these mouse types.
