redirecting input to a file -- not exiting when "null" entered

[jdubya103]

Hello all. I'm having trouble with this program used to delete and rebuild files. I need to stop inputting into the file when the null "quit" is entered. Also my, "Added...." , only displays every other input. I'm guessing my counter is only adding every other input also.
Here's the section...

echo -n "Would you like to rebuild file?"
read reply

case "$reply" in
[Yy]* )
echo "Start inputing information..."
while [[ "$line" != "QUIT" || "$line" != "quit" ]]
do
read line
line >> $f
echo "Added..."
count=$[$count +1]
done
echo "You have ""$count" "lines in the file."
exit
;;
[Nn]* )
echo "Ok. Goodbye."
rm "$f"
exit
;;
* )
echo "You must enter YES or NO!"

;;

esac

hi

what do you think `line >> $f` does ?

you need to read line before testing it against QUIT or quit.
