Question about linux template

Hello,

I'm trying to create a template for a linux server but it's not working. In the template I'm trying to run the script below:

Script Arguments:

bash ${teste}

Script Body:

#!/bin/bash

memory=`free -m |grep Mem: |awk '{print $2}'`

echo $memory

But, I'm not getting any return in Output Result:.  Could anyone give me a little help to understand where is the mistake.

OBS1: The linux credentials are correct

OBS2: This script works well directly on linux.
