If you'd like to run these examples yourself, go ahead and fire up the Power Shell ISE. An if statement is constructed as follows: This does not return true, as expected, and thus we see the message from the code in the else portion of the if statement.

While this example is a little extreme, it is something that can happen.

The exception Type Name is used later when we catch specific errors.

Looks like to get the exception's message in string format we'd use: Terminating errors in Power Shell mean that the script can no longer continue to run with the information it has encountered, or has been given.

This is a special variable in Power Shell that allows you to control what happens when a non-terminating error is encountered. As you can see, with a non-terminating error, the next command in the sequence is executed. Let's set the $error Action Preference automatic variable to Stop, and re-run the same command.

Cmdlet's and functions/scripts/modules that use [cmdletbinding()] enable utilization of the -Error Action common parameter.

If it is non-terminating, we can force it to become a terminating error, and then choose how to continue.

The simplest method of validation is the if statement.You can force non-terminating errors to become terminating errors in Power Shell. This is not always needed, but it is good to know that you can do it if you come across a use case for yourself.You can do it at a global way for the session via the $Error Action Preference variable.The Finally block contains the code you'd like to run after the event has occurred. It is worth noting that finally block is not required.Here is an example using Try/Catch/Finally: The code in the Try block executes and we see the output of Write-Host. As we learned earlier, that is the string value of the exception that raised the error.No need in this case, as we're simply using the command for validation.
