Can I also suggest:
1. Check command line parameters and print quick usage info, consider -h help parameter and the ability to pass prompted value in as command options.
2 .Proper validation of entered data/parameters, e.g. ensure response to y/n prompts is valid (what are you using d1 and d2 for anyway), ip addresses are pingable
3. Good naming of function and variables - try to describe what they do/store e.g. "comparison" is less than informative.
4. Try to write a manual page that fully describes the script and any pre-requisites.

Does anyone know the answer to this?
When I run "sum -r" on a file that I've down loaded from the sco website, the 1st set of numbers differs from the checksum on the download page but the
2nd set matches.
If I try to install the patch, I get errors.

timedsetup
timedsetup(8) System Manager's Manual timedsetup(8)
NAME
timedsetup - Performs initial setup of the time server daemon (timed).
SYNOPSIS
/usr/sbin/timedsetup
DESCRIPTION
The timedsetup command is an interactive script that can be used to perform initial time service configuration for your system.
By default, timed does not start at boot time. The timedsetup script asks if you want the timed daemon to be started at boot time, and
prompts you for any options to pass to the timed daemon whenever it is invoked. The script then starts the timed daemon.
For more information on the timed options, see the timed(8) reference page.
Note
The timed daemon is provided for compatibility. Tru64 UNIX also provides support for the Network Time Protocol (NTP) through the xntpd
daemon. Compaq recommends you use NTP for time synchronization. If your system is configured to run NTP, the timedsetup command passes
the -E and -M options to the timed daemon by default.
If you plan to run both the timed daemon and NTP, you should configure NTP first.
RESTRICTIONS
In configurations with two or more hosts each connected to the same two or more subnetworks, only one of the host can run the timed with
the -M option.
FILES
Specifies the command pathname The timed startup and shutdown script Specifies timed parameters pertinent to a specific system
