In this blog post I will show you an approach that works for PowerShell scripts that can be called from both PowerShell and batch scripts, where the command to be executed can be specified in a string, execute in its own context and always return the correct error code. Below is a kind of transcript of the steps that I took to get to an approach that works for me. It is a transcript of the steps I took, for the conclusions just jump to the end. In many blog posts you can read about calling a PowerShell script that y

Determine the Status of the Last CommandProblemYou want to get status information about the last command you executed, such as whether it succeeded.SolutionUse one of the two variables PowerShell provides to determine the status of the last command you executed: the $lastExitCode variable and the $? variable.$lastExitCodeA number that represents the exit code/error level of the last script or application that exited$? (pronounced "dollar hook")A Boolean value that represents the success or failure of the last commandDiscussionThe $lastExitCode PowerShell variable is similar to the %errorlevel% variable in DOS. It holds the exit code of the last application to exit. This lets you continue to interact with traditional executables (such as ping, findstr, and choice) tha
If you want to save some time, skip reading this and just use my PowerShell Script Boilerplate. It includes an excellent batch file wrapper, argument escaping, and error code bubbling. PowerShell.exe doesn’t return correct exit codes when using the -File option. Use -Command instead. (Vote for this issue on Microsoft Connect.) This is a batch file wrapper for executing PowerShell scripts. It forwards arguments to PowerShell and correctly bubbles up the exit code (when it can). PowerShell.exe still returns a passing (0) exit code when a ParserError is thrown. Even when using -Command. I haven’t found a workaround for this. (Vote for this issue on Microsoft Connect.) You can use black magic to include spaces and quotes in the arguments you pass through the batch file wrapper to PowerShell. PowerShell PowerShell is a great scripting environment, and it is my preferred tool for writing build scripts for .NET apps. Exit codes are vital in build scripts because they are how your Continuous Integration server knows whether the build passed or failed. This is a quick tour of working with exit codes in PowerShell scripts and batch files. I’m including batch files because they are often necessary to wrap the execution of your PowerShell scripts. Let’s start easy. Say you need to run a command line app or batch file from your PowerShell script. How can you check the exit code of that process? # script.ps1 cmd /C exit 1 Write-Host $LastExitCode # 1 $LastExitCode is a special variable that holds the exit code of the last Windows based program that was run. So says the documentation. Remember though, $LastExitCode doesn’t do squat for PowerShell commands. Use $? for that. # script.ps1 Get-ChildItem "C:\" Write-Host $? # True Get-ChildItem "Z:\some\non-existant\path" Write-Host $? # False Anytime you run an external command like this, you need to check the exit c
