root user not executing commands in shell script in a remote machine

I have created a shell script as given below.But it is not reading username and password.What Iam expecting form this script is to login as a normal user to a remote machine and login to root user to run some commands there.

ssh -t [email protected] '
  echo "user logined !";
  su root -c "
    echo Give username :;
    read username;
    echo Give password :;
    read password;
    echo $username;
    echo $password;
  ";
'

You need to escape the $'s for the variables inside the quotes:

ssh -t [email protected] '
  echo "user logined !";
  su root -c "
    echo Give username :;
    read username;
    echo Give password :;
    read password;
    echo \$username;
    echo \$password;
  ";
'

Otherwise, the shell created by the ssh command as the qbadmin user is going to perform string interpolation on $username and $password before executing the su command.
