Thanks alot for replying me .....

My requirement is to send only his details to his user id.. But I was unable to do that.......

Here, I was reading each line and storing every 4th line and sending all other details as well(but it's not my requirement).
I has to send only his particular details as I mentioned....

cat myfile.txt | while read line
do
count=`expr $count + 1`
if [ `expr $count % 4` != 0 ]
then
  mail -s "Please check your details" $line < mytext.txt
fi
done

Please help me.....

cat myfile.txt | while read line
do
count=`expr $count + 1`
if [ $count -eq 1 ]
then
    detail_1=$line
elif [ $count -eq 2 ]
then
    detail_2=$line
elif [ $count -eq 3 ]
then
    detail_3=$line
elif [ $count -eq 4 ]
then
    count=0
    echo $detail_1" "$detail_2" "$detail_4|mail -s "Please check your details" $line
fi
done

This will do your work, tough not so optimized.

Don't forget the input file. Note that this method is more efficient than cat'ing the file and piping it to the while loop (you might get a useless use of cat award reconstruction of the Award text. :slight_smile: One less process needed. There are some other good tips on that page too.

In a compact way...

cat <input_file> | paste -d, - - - - | sed 's,^,echo \",g;s,\,,\" | mail -s \"Record Details \" ,3' | sh
