My guess is that you are using a "while read" loop and redirecting a file to standard input. If you want to read from the controlling terminal during the loop, try...
Code:
 read REPLY < /dev/tty

Or use a different file descriptor for the loop...
Code:
exec 3<file1
while read -u3 LINE
do
  echo $LINE
  read REPLY
  : etc
done
exec 3<&-
