you was originally going to accept
y|Y|yes) for user input, so users being users, you've really no
idea what they'll type, just for kicks or to give you a hard time.
all the possible options they could use:
yes
YES
YEs
yES
yeS
YeS
yEs

When i give users a choice, I want either a definate positive or a negative,
anthing else is considered invalid and they'll be reasked until they give a proper response.

This is my suggestion:

Code:

#!/usr/bin/ksh

until [[ $answer = "Y" ]] || [[ $answer = "N" ]]
do
        echo "Do you want to start the process 1-5 Y/N?"
        read answer
        answer=`echo $answer | tr [:lower:] [:upper:]`
        case $answer in
           Y|YES)
                answer=`echo $answer | cut -c1`
                # /usr/home/myhome/script.ksh
                print "Process 1-5 Started. Done."
                ;;
           N|NO)
                answer=`echo $answer | cut -c1`
                print "Process 1-5 Not Started. Exiting Now"
                ;;
                
           *)
                print Unexpected Input: $answer  Retrying
                ;;
        esac

done

Note: I commented out your
/usr/home/myhome/script.ksh
to test.

shunit2

SHUNIT2(1)																SHUNIT2(1)

NAME

       shunit2 - A unit test framework for shell scripts

SYNOPSIS

       shunit2 unitfile

DESCRIPTION

       shUnit2 is a xUnit unit test framework for Bourne based shell scripts, and it is designed to work in a similar manner to JUnit, PyUnit,
       etc.. If you have ever had the desire to write a unit test for a shell script, shUnit2 can do the job.

       You can either run shunit2 directly from the commandline and specify the unit file or directly source the shunit2 executable.

       If you directly execute shunit2 and don't specify a unitfile shunit2 assumes a empty testfile and will return without an error message.

EXAMPLE

       Simple script to test if 1 equals 1

	   #! /bin/sh
	   testEquality()
	   {
	     assertEquals 1 1
	   }

	   # load shunit2
	   . shunit2

       Execute shUnit2 unit tests directly from the commandline

	   shunit2 /path/to/unit/file

OPTIONS

       shunit2 does not support any commandline options at all. You can either source shunit2 to execute your unit tests or directly run shunit2
       as a commandline script.

SEE ALSO

       For more information see http://code.google.com/p/shunit2/ or have a look at the installed documentation in /usr/share/doc/shunit2/
