I tried to solve it, but the output that I'm getting is not perfect. Here is the script that I've come up with:

#!/bin/sh
arg_1=$1
echo "arg passed by user is:${arg_1}"
res=$(awk -F= -v name=${arg_1} '$1 == name {value=$2;exit} END { print (value)?value:"not found"}' sample.param)
echo "mapping is $res"
if [ "${res}" = "not found" ]; then
echo "key not found"
help
exit 1
fi

key=Student_${res}
echo "key:${key}:"
param_file=`grep '${key}=' sample.param | awk -F"=" '{print $2}'`
echo "param file is:${param_file}"

---------------------------------------------------------

But the output is not coming properly especially the last result i.e. the value of "param_file" variable which is displayed as blank though the value is present in the param file.

Now since you have done something, it feels good to guide you.
1) May be help you want to write later...
2) remove the quotes from '${key}=' and make it just ${key}
