the format is wrong

Code:

case "$ans" in
y | Y )
      echo yes
      ;;
* )
      echo default
      ;;
esac

I don't know what you mean by "the script is still running".

the "*" clause will match "N".

Sir according to the script if the user enters either N/n then the script must ask him to enter a valid number,instead here its gng to the nxt step and executuing it

Not according to the script you posted....

Code:

echo "\nAre you sure you entered the right Destination Environment? y[n] : \c \n"
read ans
case ${ans} in
y/Y)
*);;
esac

Nothing about case "N", nothing about "valid number". Your case statement is just plain wrong.
