Search Replace and Update a file
hi,
I am stuck at a place. Please help me out. Here is what i need to do.
Search for a pattern in a propertyfile and change only at one occurance. I have these statements and assignment as a part of the propertyfile
Code:
 #Note : The Address should be replaced with actual address dynamically.
 ServerName=Address

Now i want to search the propertyfile, and change Address only in the assignment and not in the comment. Somethinglike
Code:
#Note : The Address should be replaced with actual address dynamically.
 ServerName=Actual Address

Here is what is my thought:
Code:
x=`grep ServerName Property.file |awk -F= '{print $2}'`
sed -i "s/$x/Actual Address/" Property.file

But the above code will replace "Address" with "Actual Address" even in the comment part.
how can i achieve this... Is there a way i can use sed inside awk, or pipe the result of awk to sed and change the property file
Any help is greately appriciated

NAME

       rarpc - Reverse Address Resolution Protocol client

SYNOPSIS

       count] interface_name

DESCRIPTION

       the Reverse Address Resolution Protocol client, implements the client portion of the Reverse Address Resolution Protocol (see It sends RARP
       requests for the specified interface's hardware address and waits for the response from the RARP server.  can be used during boot-time ini-
       tialization to find the IP address of an interface.  To do so, set the i] variable of interface i with in

       Options are:

	      Print debugging information.

	      Use ethernet encapsulation only.

	      Use SNAP encapsulation only.

	      Transmits count requests and waits for each one to time out before
			       giving up.

	      interface_name   Identifies the interface to request information about.

       If  a  response	is  received, it prints the IP address to its standard output.	This information can be used to configure the interface as
       seen in

       If a response is not received, the client will retransmit after 2 seconds, and then after 4 seconds.   After  that,  retransmissions  occur
       every 8 seconds.

RETURN VALUE

       Exit  status  is 1 if the command fails or no RARP response is received.  Exit status is 0 and the IP address is printed to standard output
       if a response is received.

LIMITATIONS

       1. The client cannot be run at the same time a daemon is running on the same interface.

       2. The client supports only ethernet, 100VG and FDDI network interfaces.
