#!/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?
