Mhm ... I don't have that much experience with bash, but maybe I can help you anyway. What are you trying to do?

Assignment, if you can help me with either one that would be great!

The other one says enter a command to terminate job #3 so I did kill %3 now its saying assume kill %3 didn't work

So ... if I understand right, you want to insert some numbers (specific ones?) and sum them up? I'm not sure what you mean with "my assignment wants me to exactly print this message out"

Basically if i did add2 4 -3 12 9

With my script it should output:22

If i did add2 4 -3 twelve nine
It should output
twelve
Sorry, 'twelve' is not a number

You mean you don't want it to echo out the second error message?

Or do you just want the sum as output, not every single number you typed?

Sum as output only

Or do you mean that it should print out "twelve" instad of some weird numbers?

If I did add2 2 3 nine it should print out

Nine

Sorry, nine is not a number

Ok, I understand.

Oki

Ok, what about this?


#!/bin/bash

echo -------
echo test

sum=0

for i in $@; do

if [[ $i != *[[:digit:]]* ]]
then
echo ""
echo "Sorry, '$i' is not a number, skipped"
else
sum=$[sum+$i]
fi

done

echo ""
echo "Summary: $sum"

Remove the echo commands at the top if you don't want to get your input printed. I just added them for tests.

Ok thanks ill try it out

it works but my assignment says its wrong fuck sake it wants me to output this to /dev/null but the shit is still echoing to the command line

echo $number | grep "[^a-z]" >> /dev/null

Oh ...
Sadly, I can really test this since I'm working on windows, but maybe you could take a look here to get the output to /dev/null (also look at the commentaries):

You tried that? Hope it helps.
