Problem with awk script
Hi
Can anyone help me in this Problem
File1
#########################
HOLI 123 AND ONE TWO THREE AMITABH SAMSUNG
POLI AND TWO SENSE CRYING WING
PPIN TBFLAG I B AND OROLE TB_HOT=" DCT" TB_CAT=" CAT" TC_NOT=" AND"
+PIN TB=" HOT" TB_GATE=" KOT" TB_LATE=" MAT" TC=LOT
MAT DAT SAT GATE IS A NAND AND PLAN ON THE RIGHT INFORMATION
##########################
I need to write a awk script should match word PPIN TBKFLAG and then remove the Key words TB_GATE=" KOT" TB_LATE=" MAT" TC=LOT
Rest should be same
Final file 1 should be like this
######################
HOLI 123 AND ONE TWO THREE AMITABH SAMSUNG
POLI AND TWO SENSE CRYING WING
PPIN TBFLAG I B AND OROLE TB_HOT=" DCT" TB_CAT=" CAT" TC_NOT=" AND"
+PIN TB=" HOT"
MAT DAT SAT GATE IS A NAND AND PLAN ON THE RIGHT INFORMATION

Thanks and Regards

NAND(4) BSD Kernel Interfaces Manual NAND(4)
NAME
nand -- NAND Flash framework
SYNOPSIS
device nand
DESCRIPTION
The FreeBSD nand framework consists of a set of interfaces that aim to provide an extensible, object oriented environement for NAND con-
trollers and NAND Flash memory chips from various hardware vendors, and to allow for uniform and flexible management of the NAND devices. It
comprises of the following major components:
o NAND Flash controller (NFC) interface.
Defines methods which allow to send commands as well as send/receive data between the controller and a NAND chip. Back-end drivers for
specific NAND controllers plug into this interface and implement low-level routines for a given NAND controller.
This layer implements basic functionality of a NAND Flash controller. It allows to send command and address to chip, drive CS (chip
select line), as well as read/write to the selected NAND chip. This layer is independent of NAND chip devices actually connected to the
controller.
o NAND chip interface.
Provides basic operations like read page, program page, erase block. Currently three generic classes of drivers are available, which pro-
vide support for the following chips:
o large page
o small page
o ONFI-compliant
This layer implements basic operations to be performed on a NAND chip, like read, program, erase, get status etc. Since these operations
use specific commands (depending on the vendor), each chip has potentially its own implementation of the commands set.
The framework is extensible so it is also possible to create a custom command set for a non standard chip support.
o NANDbus.
This layer is responsible for enumerating NAND chips in the system and establishing the hierarchy between chips and their supervising
controllers.
Its main purpose is detecting type of NAND chips connected to a given chip select (CS line). It also allows manages locking access to the
NAND controller. NANDbus passes requests from an active chip to the chip controller.
o NAND character / GEOM device.
For each NAND chip found in a system a character and GEOM devices are created which allows to read / write directly to a device, as well
as perform other specific operations (like via ioctl).
There are two GEOM devices created for each NAND chip:
o raw device
o normal device
Raw device allows to bypass ECC checking when reading/writing to it, while normal device always uses ECC algorithm to validate the read
data.
NAND character devices will be created for each NAND chip detected while probing the NAND controller.
