You check to see if stdin is a terminal, but that's not conclusive. One way
to know for sure is to look at the name of the process that launched you:
if [ ! -t 0 ] ; then
echo "no tty, possibly run from cron"
fi
parent=$(ps -o command= -p $PPID)
case $parent in
*cron* ) echo "parent is $parent, almost certainly cron" ;;
esac
