Today’s post (and this blog's inaugural post!) is An Introduction to Error Handling in PowerShell. We will discuss error types, the $error variable, error action preferences, try/catch blocks, and $lastexitcode.The first requirement is to understand the types of errors that can occur during execution.Terminating vs. Non-Terminating Errors:.

Terminating Error: A serious error during execution that halts the command (or script execution) completely. Examples can include non-existent cmdlets, syntax errors that would prevent a cmdlet from running, or other fatal errors.

Non-Terminating Error: A non-serious error that allows execution to continue despite the failure. Examples include operational errors such file not found, permissions problems, etc.Update: Writing a cmdlet?

For further information regarding how a cmdlet should determine when to throw a terminating error or non-terminating error, MSDN has a nice.Update: Want to know if an error you encountered is terminating or non-terminating? Check to see if the error behavior is affected by changing the $ErrorActionPreference. According to the MSDN, 'Neither $ErrorActionPreference nor the ErrorAction common parameter affect how Windows PowerShell responds to terminating errors (those that stop cmdlet processing).'

.The $error variable:When either type of error occurs during execution, it is logged to a global variable called $error. This variable is a collection of PowerShell Error Objects with the most recent error at index 0.

On a freshly initialized PowerShell instance (no errors have occurred yet) the $error variable is ready and waiting as an empty collection. PS C: ThisCmdlet-DoesNotExist. The term 'ThisCmdlet-DoesNotExist' is not recognized as the name of a cmdlet, f. unction, script file, or operable program. Check the spelling of the name, or i. f a path was included, verify that the path is correct and try again.

PS C: $error0. The term 'ThisCmdlet-DoesNotExist' is not recognized as the name of a cmdlet, f. unction, script file, or operable program. Check the spelling of the name, or i. f a path was included, verify that the path is correct and try again. At line:1 char:24. + ThisCmdlet-DoesNotExist.

The statements behave similar to the statements of the same name found in C# and other languages.The behavior of try/catch is to catch terminating errors (exceptions).

This means Non-terminating (operational) errors inside a try block will not trigger a Catch. If you would like to catch all possible errors (terminating and non-terminating) – then simply set the error action preference to Stop. Remember that Stop error action forces a non-terminating error to behave like a terminating error, which means it can then be trapped in a catch block. Here is an example:.Update: In almost all cases, non-terminating errors will not trigger a catch.

However I did recently observe a situation where a non-terminating error did trigger a catch block. It wasn't from a cmdlet, but an exception generated from directly calling a method on a.net object. So keep in mind that behavior might be possible. PS C: $error0.Exception.GetType.FullName. System.Management.Automation.ItemNotFoundExceptionHandling Errors from non-PowerShell processes:What happens when your script needs to run an external process from PowerShell and you want to know if it succeeded? An example would be a cmdline tool such as robocopy.exe. It’s an external application that returns an exit code upon completion.

But since it is an external process, its errors will not be caught in your try/ catch blocks.To trap this exit code utilize the $LastExitCode PowerShell variable.When the launched process exits, PowerShell will write the exit code directly to $LastExitCode. In most cases an exit code of 0 means success, and 1 or greater indicates a failure. Check the external tool's documentation to verify of course.Here it is seen in action.

Great article. I'd like to ask about a problem in one of mscripts, though.

I have a script with a try/catch block, and in the catch, I call a function I've written called RollbackEverything. I can call RollbackEveything from the try block with no problem, but when I call it from the Catch block, I see the error 'The term 'RollbackEverything' is not recognized as a cmdlet, function, operable program, or script file.

Verify the term and try again.' What is happening, and is there a way to fix it?.
