Welcome to the forum.


You're problem is quite ubiquitous and has been solved / commented on in these fora more than several times. Try the search function, or one of the links given at the lower left of this page under "More UNIX and Linux Forum Topics You Might Find Helpful".


The code with which you addressed your problem is not the most efficient one. Did you consider just reading the variables? Like
Code:
{ read dummy
  while IFS=, read a b c d e f dummy
     do   echo $e
          echo $f

     .
     .
     .
     done
 } < $file
