Writing PowerShell scripts can be a fulfilling task. After all, you write something to assist with a task or procedure so you can focus on the result, not the task itself. But what if your script tries to run an action and is unsuccessful, for example, when a user the script attempts to manipulate is invalid or the signed-in account has insufficient permissions to run a cmdlet? And do not forget the peculiarities of the online world, such as a network connection dropping or an authentication token expiring.
This is where one of the often-undervalued aspects of writing resilient and “a less optimistic version” of scripts comes into the picture: exception handling, the topic of the fifth part in the Practical PowerShell series.
