shell script to search a string and delete the content
Hi,
I've a shell script e.g.

#!/bin/bash
echo "Enter the next hop id"
read nhid
echo "enter the IP address"
read IP
echo "enter the interface name"
read name
echo "enter the enable/disable state"
read state
exit 0

now from this script i want to search strings in another (.cam)
file e.g. the cam file is

BEGIN
next hop id value nhid
IP address value 192.168.1.101
Interface name xyz
enable disable state 1
END

now i've to search for the string 'next hop id value' in this cam file then delete the values in front of this string untill a new line starts and then append the user input value stored in the variable in front of this string.
similarly for other fields.

like if previously the cam file is as above and the user input value for ip address is 111.111.111.111, interface name is abc and enable/disable state is 0. finally this cam file should become like this:

BEGIN
next hop id value nhid
IP address value 111.111.111.111
Interface name abc
enable disable state 0
END


can anyone help me out in this.....
Thanks in advance!!

bouncesaying(1)                                               General Commands Manual                                              bouncesaying(1)

NAME

       bouncesaying - perhaps bounce each incoming message

SYNOPSIS

       in .qmail: |bouncesaying error [ program [ arg ...  ] ]

DESCRIPTION

       bouncesaying  feeds  each  new mail message to program with the given arguments.  If program exits 0, bouncesaying prints error and bounces
       the message.

       If program exits 111, bouncesaying exits 111, so delivery will be retried later.

       If program exits anything else (or does not exist), bouncesaying exits 0, so the rest of .qmail will be processed as usual.

       Note that it is not safe for program to fork a child that reads the message in the background.

       If program is not supplied, bouncesaying always bounces the message:

          |bouncesaying 'This address no longer accepts mail.'

       WARNING: If you create a .qmail file to enable bouncesaying, make sure to also add a line specifying delivery to your normal mailbox.
