Both of those have non-obvious gotchas. A good writeup on error > handling in PS (not Puppet-specific) is here: > http://blogs.technet.com/b/heyscriptingguy/archive/2011/05/12/powershell-error-handling-and-why-you-should-care.aspx > Another great writeup for PowerShell confusion is http://joshua.poehls.me/2012/powershell-script-module-boilerplate/ The tl;dr of PowerShell scripts is that parser errors (incorrect PowerShell) will always exit with 0, so test your scripts with PowerShell and look at the last exit code. Another is that even setting $ErrorActionPreference = 'Stop' (to catch non-terminating errors) doesn't appear to catch external command errors (versus powershell function calls): [image: Inline image 1] PowerShell.exe -NoProfile -NonInteractive -NoLogo -ExecutionPolicy Bypass -Command "$ErrorActionPreference = 'Stop';reg /query bob; Write-Host 'yo'" > > > - Peter > > > > On 08/27/2015 08:38 AM, Thomas Bartlett wrote: > > Hi Guys, > > So I've been working with puppet on windows and I think my approach is all > wrong.
