How to loop a script?

Hi. Simple question here about bash scripts.

I have a script I use for scanning documents. Due to a hardware problem I can't scan in batches. So instead of exiting after each document, I want the script to loop and ask "Start again?".

This is as far as I've got:

Code:

dialog --yesno "Go ahead?"
if [ $? -eq 0 ] ; then

[script here]

else exit
fi

If I can loop that, then there will be a way to get out after each scan. But even the dialog is overkill, surely...?

Ideas appreciated!

Maybe this will get you started...

Code:

#!/bin/bash

while true ; do
clear
tput cup 3 16; echo "Scan Menu"
tput cup 4 12; echo "~~~~~~~~~~~~~~~~~~~"
tput cup 6 12; echo "1. Run a scan job"
tput cup 7 12; echo "2. Exit from menu"
tput cup 9 12; echo -n "Please enter your choice (1-2): "

read sel

case $sel in
1) ./myscript ;;

2) exit ;;

esac
sleep 10
done

You can also press Ctrl c to end the menu script

That got me started - and finished. And I even learned something in between!

Thanks homey, I appreciate it.
