bash While? loop choice menu

Question

#!/bin/bash
echo "Please enter your Host Name"
read hname
echo "You have entered $hname, is this correct?"
select yn in "Yes" "No"; do
    case $yn in
        Yes ) sh runscript.sh; break;;
         No ) ;
    esac
done

How can I make this work so that if answer is incorrect go back to ask it again? I know I need a while loop to achieve this but don't know how to write it up.

This ought to do it:


while [ "$yn" != "Yes" ]; do
 echo "Please enter your Host Name"
 read hname
 echo "You have entered $hname, is this correct? (Yes or No)"
  read yn
done
sh runscript.sh

Here's another one you helped me out on writing:

#!/bin/bash

        while ["$yn" != "Yes" ]; do

    echo "Choose your type of installation"

    echo "1) Home Media Server"

    echo "2) Home Communication Server"

    echo "3) Enterprise Communication Server"

    echo "4) Hosting Server"

    echo "5) Individual Packages"

    echo "6) exit"

    read case;



    #simple case bash structure

    # note in this case $case is variable and does not have to

    # be named case this is just an example



    case $case in

        1) echo "You have entered Home Media Server, is this correct? (Yes or No)"

      read yn

                echo "Running script for Home Media Server";;



        2) echo "You have entered Home Communication Server, is this correct? (Yes or No)"

      read yn

                echo "Running script for Home Communication Server";;



        3) echo "You have entered Enterprise Communication Server, is this correct? (Yes or No)"

      read yn

                echo "Running script for Enterprise Communication Server";;



        4) echo "You have entered Hosting Server, is this correct? (Yes or No)"

      read yn

                echo "Running script for Hosting Server";;



        5) echo "You have entered $hname, is this correct? (Yes or No)"

      read yn

                echo "Running script for Individual Packages";;



        6) exit

    esac

Thanks once again.
