#!/usr/bin/ksh
echo Please enter
while read n
do
echo $n >> datafile
done

question:

How can I enject an if statement that if the users enter 0 (zero) the program will exit?

this is what I have but not working

#!/usr/bin/ksh
echo Please enter number
while read n
do
if $n=0
then
exit
else
echo $n >> datafile
fi
done


Thanks!
