If I understand your question/scenario, you probably want to redirect your
read from /dev/tty (a la "$ read < /dev/tty someVariable").  You can also
use the tty command to figure out if there is actually a tty associated
with the shell (e.g., to provide some useful default behavior if the script
is run from, say, a crontab or at job).
