parallel while loop based on the file records

Hi,


I need to execute parallel with while loop.

Input File(source_file.csv) contains filenames the below

Code:
source_file.csv file contains

Customer1.txt
Product1.txt
Sales.txt
Emp.txt
Dept.txt

Based on the number of rows that file I want to run the script n' times.
Code:
while source_file.csv|read line
do
       cat $line  # I am applying some logic 
done

the script should run in parallel. I am having some problem with the while loop.
Any help greatly appreciated.

Thanks -suri

"run in parallel" means? For each line in the csv file we can trigger the script.

Whats wrong with your while loop? Try this...

Code:
#!/bin/ksh

while read line
do
  echo $line
  # execute your script here
done < source_file.csv

regards,
Ahamed
