I don't program X, nevertheless there's nothing there that I can see
which checks for the existence of an X server. Looks like all the error
checking has been omitted for tutorial clarity. Here's a hint on
avoidance until you reach the tutorial which does it in code...
#! /bin/sh
if [ -z "$DISPLAY" ]
then
echo "No X atm"
exit `false`
else
"$HOME"/tortoise1
fi
Either of "info bash" or "man ash" (ash=sh).

echo $DISPLAY
man X

Loosely, you just need to launch a command shell from inside X and it'll
run. Fyi it does work.
