Powershell Return Error Code To Cmd

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 powershell $lastexitcode 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 powershell exit command 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 powershell error code 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 $? # False Anytime you run an external command like this, you need to check the exit code and throw an exception if needed. Otherwise the PowerShell script will keep right on trucking after a failure. # script.ps1 cmd /C exit 1 if ($LastExitCode -ne 0) { throw "Command failed with exit code $LastExitCode." } Write-Host "You'll never see this." Writing these assertions all the time will get old. Fortunately you can use a helper function, like this one found in the excellent psake project. # script.ps1 function Exec { [CmdletBinding()]

When running from the console, control is immediately returned while MSI forks a new process to run the installer. There is no way to change this behavior. What you'll probably need to do is use Get-Process to find a process named msiexec, and wait for it to finish. There is always an msiexec process running, which handles starting new installers, so you'll need to find the msiexec process that started after your install began. $msiexecd = Get-Process -Name 'msiexec' C:\Users\Admin\Documents\Setup-2.0.exe exe ` /s ` /v"EULAACCEPTED=\"Yes\" /l*v c:\install.log /qn" $myMsi = Get-

It holds the exit code of the last application to exit. This lets you continue to interact wi
