Expr in Shell
I am creating a shell program. I am using expr but the output is not the one that is expected. This is the code i am trying is
echo "adding two numbers"
echo "Enter First Number"
echo "Enter second Number"
echo "The sum of $a and $b is 'expr $a + $b'"
but instead of giving me the total of two numbers, its giving me the output as "The sum of 2 and 3 is 'expr 2 + 3'". Please help.
