Question

I’m trying to write a simple bash script that takes two parameters and sums them. How can I fix this?

#!/bin/bash
add = $(($1+$2))
echo Addition       : $add

# sample 7 15

Answer 1

Just remove the ‘space’ before and after the ‘=’.

                    add = $(($1+$2))

                          to

                    add=$(($1+$2))

So your complete pgm will be like this

#!/bin/bash
add=$(($1+$2))
echo Addition       : $add

# sample 7 15
