just in case you were wondering:

#! /usr/bin/awk -f

BEGIN { FS = OFS = "," }

{
  for (i = 0; i < NF; i++)
    if (!$i) $i = "''";
  print;
}


awk is a very nice simple language and perfect for these sorts of tasks.

(you can make this into a much shorter one-liner, if you wanted to use
it in a shell script)
