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.

Answer 1

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
