Alister,

Thank you so much for your help! That did exactly the trick. I modified the script to the following:

Code:
echo -e "From: \t"$frm_Zone"\tTo:\t"$to_Zone
                        
printf '%-5s %-20s %-20s %-20s %-15s %-10s\n' $pol_Id $src_Address $dst_Address "$pol_Service" "$pol_Action" "$pol_Name"

#finding the array with the largest index
#so we now how many times to run the for loop

lnAddy=`echo ${#srcAddyArray[*]}`
lnSrc=`echo ${#dstAddyArray[*]}`
lnSvc=`echo ${#serviceArray[*]}`

max2 $lnAddy $lnSrc
temp=$?
max2 $temp $lnSvc
longest=$?

for (( i = 0; i < longest; i++ )) do

              printf '%-5s %-20s %-20s %-20s\n' "" "${srcAddyArray[$i]}" "${dstAddyArray[$i]}" "${serviceArray[$i]}"

done

I ended up having to print one blank column so it lined up properly, but now the output is exactly how I wanted:
Code:
From:   Trust-cs        To:     Untrust-Firn
615   Any                  mail.acast.xxxx.xxx  tcp-6777 (wo 85073)  Permit Nat SRC  wo 85073  
      69.xx.xxx.1          mail.xxxxxxx.edu     tcp-6788 (wo 85073) 
      75.xxx.44.1          my.xxxxxx.edu        tcp-8008 (wo 85073) 

From:   Trust-cs        To:     DMZ-acad
596   Any                  69.xx.xxx.31         TCP-15888            Permit                    
      tables.noc.xxxx.xxx  mages.icecrown.com   tcp-16888           
                                                TCP-17888           
                                                UDP-17888           
                                                UDP-18888

Thank you so much for your help!
