You are developing a Bash script to test whether a given host is up. Users will run the script in the following format:

$1 will refer to the first positional argument.
You are developing a script to ensure that the M: drive is mapped consistently to the same network folder on all client workstations. What type of construct might you use to ensure the script runs without errors?
Click to show answer

You are developing a script to scan server hosts to discover which ports are open and to identify which server software is operating the port. What considerations should you make before deploying this script?

While the risk is low, scanning activity could cause problems with the target and possibly even crash it. Test the script in a sandbox environment before deploying it. Security software might block the operation of this script, and there is some risk from the script or its output being misused. Make sure that use of the script and its output are subject to access controls and that any system reconfiguration is properly change-managed.
