Buddy.. I told you.. you need to work.. dont rely on spoon feeding.. Anyways.. here is the code.. this is flexible code.. you can have n number of fields.. separated by any delimiter..

Code:

#!/bin/ksh
#
# usage $0 <file> <delimiter> <Number of fields>

file=$1
delimiter=$2
num=$3
cnt=0
i=0

while read line
 do 
  let cnt=$cnt+1
  while [  $i -lt $num ]
  do
   let i=$i+1
   field=`echo $line | cut -f$i -d"$delimiter"`;
 
  if [ "$field" = "" ]; then
        print "\nERROR: Line #$cnt \"$line\" is missing field #$i.\n"
        break
  fi
  done
  i=0
 done < $file

I hope this helps..
