I have found a way to do what I want. To me it is ugly, but at least it does
work as intended. For the benefit of the archives (and those searching them)
here's the code:
echo Some prompt (press ESC to exit)
if read -n 1 -s -t $TIMEOUT KEY ; then
KEY=$( echo $KEY | od -t x1 | awk '{ print $2}' )
if [ "$KEY" == '1b' ]; then
echo BAILOUT: nothing changed
exit 0
fi
echo Do something useful here...
else
echo TIMEOUT: nothing changed
exit 0
fi
