Prime Generation Code Not Working Properly
My code for the generation of prime numbers from 2 to a value(given at run time) as fallows is not working. Can you assist me?
Code:
clear
echo "Enter the Maximum Number"
read max
for(( i=2; i <= $max; i++ ))
do
if [ `expr $i % 2` -eq 0 ]
then
break
else 
for(( j=i; j <= $max/2; j++ ))
do
if [ `expr $i % $j` -eq 0 ]
then break
else echo -n $i; 
fi
done
fi
done
