#!/bin/bash - how to code?

-1

I need to make changes to my script.

my script is:

sum=0

for numberr in "$@"; do

        echo "$numberr" | grep '[^0-9+-]

        if [ $? -eq 0 ]; then

                echo "Sorry '$numberr' is not a number"

                exit  1

        fi

        sum=$((sum + numberr))

done

echo "sum"

now I need to change the script for echo and grep when typing

add2 4 -3 twelve nine

to get:

twelve

nine

1

at the moment I get the message "Sorry twelve is not a number"

you've told the script to exit when the grep fails (and you get that message); what do you want it to do?

I need to change my code in grep and echo; my answer should no longer be sorry twelve is not a number; now I need to get an answer as: twelve nine 1
