Need help with rc.d script

[Ernie Luzar]

I wrote this sh script today for dynamic dns ip updates.
When I use service dynip start command it just hangs there.
Need pointer to what I am doing wrong.

Here are the 2 scripts in question:

Script started on Mon Nov  6 18:19:18 2017
/root/bin >cat /usr/local/bin/dynip
#!/bin/sh
   #
   # Script to update the dynamic DNS pointer at your dynamic DNS 
hosting site.
   # This script runs continually and on a user defined timed cycle will
   # check the dynamic ip address of the interface facing the public 
internet
   # to determin if it has changed. If it has changed the browser URL format
   # is used to update the DNS pointer IP address at the dynamic DNS 
hosting
   # site that is hosting your Fully qualified domain to the newly changed
   # ip address.
   #
   # The default browser URL format being used is for NameCheap 
(namecheap.com).
   # NOTE: Most DNS hosting sites that provide dynamic DNS services use a
   # variation of the default browser URL format used here. A simple user
   # substitution to the "wget" command for the browser URL format used 
by your
   # dynamic DNS hosting site will allow this script to work for you.
