I would use 'local response', in shell you need to define the scope
yourself.
echo "Starting quiz..."
echo "What is 2+2?"
read response
You are using response twice in your script, given that this code is the
body of a function should use 'local' to make it only usable in the
function (function scope) and not in all of your script (global scope).
if [ "$response" == 4 ]
This is a bad practiss to use '==' in shell you can use one ('[
"$response" = '4' ]')
Given that you are comparing two strings you should also make 'four' a
string!
then
echo "You got it."
else
echo "That is incorrect."
fi
}
until [ "$response" == 4 ]; do
Same as above.
echo "Begin math quiz? (y/n)"
read response
if [ "$response" == "y" ] || [ "$response" == "Y" ]
then
A more straightforward alternative would be to use a case statement.
SECONDS=0
Why are you capitalizing your variable?
quiz
echo "The quiz took you $SECONDS seconds to complete."
else
echo "Exiting..."
exit
fi
done
HTH.
