#!/bin/bash

# This program will modify a file by substituting all instances of a specified
# IP with "DUMMYIP".  This is useful for making the IP address generic and thus
# searchable.

# Description of argument(s):
# ip_addr    An IP address.
# file_path  The path to a file which is to be modified.

# Get arguments.
ip_addr="${1}" ; shift
file_path="${1}" ; shift

# Validate arguments.
