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!!
