I want to find total for remaining two students marks also. Can someone help me with this?

You can search for `Name` and every time is found you go to the next `numm` lines and sum the scores:


#!/bin/bash
file=$1
num=$2
awk -v numm="$num" '
/Name/{
mark = 0;
printf("%s ",$2);
for ( i=0; i getline;
mark += $2;
}
printf("%d\
", mark);
}' $file


the result:


Rad 468
Din 375
Hardy 320
