These are two examples on how to write an interactive shell script, either with a YES/NO prompt and with a LIST among which the user has to choose.As always, start your script file with:

#!/bin/sh

Interactive with a YES/NO prompt:

echo "What do you like me?"
select yn in "Yes" "No"; do
    case $yn in
        Yes ) echo "So I do $USER!"; break;;
        No ) echo "Neither do I $USER"; break;;
    esac
done

After Yes ) and No) you can add a series of commands, each one delimited by a ; (semicolon) at the end.
When you finish your command sequence put ;; (two semiclon) (this way the script would be recursive)
If you do not want your script to be recursive and want to go to the next question put break;;

Interactive with a LIST from which to choose:

while :
do
 clear
 echo "Choose the mode which best fits you"
 echo "1. AUTO (default)"
 echo "2. HP generic laptop"
 echo "3. Fujitsu"
 echo "4. Acer"
 echo "5. Dell"
 echo "6. Lenovo Thinkpad"
 echo "7. UNDO TWEAK / CHANGE MODE / PRESSED WRONG DIGIT"
 echo "8. DONE TWEAKING!"
 echo -n "Please enter option [1 - 8]"
 read opt
 case $opt in
  1) echo;;
  2) sudo echo "options snd-hda-intel model=hp" >> /etc/modprobe.d/alsa-base.conf;;
  3) sudo echo "options snd-hda-intel model=fujitsu" >> /etc/modprobe.d/alsa-base.conf;;
  4) sudo echo "options snd-hda-intel model=acer" >> /etc/modprobe.d/alsa-base.conf;;
  5) sudo echo "options snd-hda-intel model=dell" >> /etc/modprobe.d/alsa-base.conf;;
  6) sudo echo "options snd-hda-intel model=thinkpad" >> /etc/modprobe.d/alsa-base.conf;;
  7) sudo sed '$d' /etc/modprobe.d/alsa-base.conf /tmp/alsa-base.conf ; mv /tmp/alsa-base.conf /etc/modprobe.d/alsa-base.conf;;
  8 ) echo "Bye $USER";
     exit 1;;
  *) echo "$opt is an invaild option. Please select option between 1-17 only";
     echo "Press [enter] key to continue. . .";
     read enterKey;;
esac
done

As before remember to end each command with a semicolon ; and to end each menu entry with double semicolon ;;
The end of the script would be an exit 1;;

to display a file as a choice of the interactive script you can use the command more

2) more /etc/resolv.conf

to require user press the Enter key to acknowledge some message:

 echo "Press [enter] key to continue. . .";
     read enterKey;;
