UNIX for Dummies Questions & Answers

All,
I am a UNIX novice with a question that I hope you can help me with.
I have a UNIX application called "Tole" that formats and displays specific information about customers. I can display the information for up to 30 customers by seperating customer IDs using commas in this format:
Tole -c 10,20,30... I would like to have the application pull the values shown after the -c argument from a .csv file (say customers.csv) and run them in groups of 30. Also, I would like the output piped and appended to a results file (say results.csv) as in: Tole -c 10,20,30 >> results.csv.
Thank you in advance for your help.
Adam

Code:

#!/bin/ksh
awk -F, '{ for(i=1; i< NF; i++) 
               if(i%30 == 0 ) {printf("%s\n", $i) }
               else  {printf("%s,",$i) } 
             END {print "" }
           ' | \
while read parms
do
      Tole -c "$parms" 
done >> result.csv

Thank you Jim. Can you take me through this command and let me know what directory this needs to go under?

Can someone tell me if I need to be logged in as root and explain what the commands mean?
Thank you,
Adam
