Hey Don,
I had to fix my shebang to #!/usr/bin/ksh, but it did not help. I have to run on ksh88 as i have no other choice and the output from your request is as follows with ksh88: The ksh88 does not like the parenthesis. ksh93 has no problem with the parenthesis, but that is not the version which i need it to run. Thanks again.

The following code in ksh88:

Code:
#!/usr/bin/ksh
set -xv
group1=("/usr/bin" "/usr/games")
group2=("/usr/local/bin" "/usr/local/games")
i=0
while [ $i -lt ${#group1[@]} ] && [ $i -lt ${#group2[@]} ]
do	echo diff -r "${group1[i]}" "${group2[i]}"
	i=$((i + 1))
done

produces the output:

Code:
Syntax error at line 3 : '(' is not expected

Don - I have a working solution, thanks to your efforts. This will allow me to take vendor code upgrades and spit out which of the property files have changes in numerous directories. This will save a ton of time, as currently we are going through each of them manually. I can't tell you now much i appreciate this. Here is the final solution. Thanks again.
Code:
#!/usr/bin/ksh
set -A old_dir /usr/version1/cmd /usr/version1/properties
set -A new_dir /usr/version2/cmd /user/version2/properties
i=0
while [ $i -lt ${#old_dir[@]} ] && [ $i -lt ${#new_dir[@]} ]
do	diff -r "${old_dir[i]}" "${new_dir[i]}" |awk 'NR==1{print $3}'
	i=$((i + 1))
done

getusershell

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME

       getusershell, setusershell, endusershell - get legal user shells

SYNOPSIS

       #include <unistd.h>

       char *getusershell(void);

       void setusershell(void);

       void endusershell(void);

DESCRIPTION

       The  getusershell()  function  returns  a  pointer  to  a  legal  user  shell  as defined by the system manager in the file /etc/shells. If
       /etc/shells does not exist, the following locations of the standard system shells are used in its place:

       /bin/bash		  /bin/csh
       /bin/jsh 		  /bin/ksh
       /bin/pfcsh		  /bin/pfksh
       /bin/pfsh		  /bin/sh
       /bin/tcsh		  /bin/zsh
       /sbin/jsh		  /sbin/pfsh
       /sbin/sh 		  /usr/bin/bash
       /usr/bin/csh		  /usr/bin/jsh
       /usr/bin/ksh		  /usr/bin/pfcsh
       /usr/bin/pfksh		  /usr/bin/pfsh
       /usr/bin/sh		  /usr/bin/tcsh
       /usr/bin/zsh		  /usr/xpg4/bin/sh

       The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells.

       The setusershell() function rewinds the file or the list.

       The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells.

RETURN VALUES

       The getusershell() function returns a null pointer on EOF.

BUGS

       All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved.
