Powershell Continue On Error
the technet powershell forum too (http://social.technet.microsoft.com/Forums/en-US/winserverpowershell/thread/ab0363eb-5803-47be-a724-8e68e0c56e7a). I received a couple of suggestions but so far nothing that explains why it is happening or what https://community.spiceworks.com/topic/106857-powershell-equivalent-to-on-error-resume-next is wrong with my Try-Catch structure. From the other forum: I am trying to find all the subfolders where the path is too long or access has been denied. I wrote the script below and when it encounter an error, the catch works, but the script exits out of the https://social.technet.microsoft.com/Forums/scriptcenter/en-US/e9ee76cd-3446-4507-b9e7-60863550fa00/powershell-trycatch-not-continuing-after-error?forum=ITCG ForEach-Object loop and finishes. The folder listed in the script has over 50,000 subfolders but stops on the 451st folder when it catches that error. I feel like something is wrong with my Try-Catch structure that I am not understanding. Any help would be appreciated. Thanks. $RootFolder = "S:\Procurement_Section\" $ErrorLog = "X:\Scripts\CountFolders\countfolders.log" $ifolders = 0 cls If (Test-Path $RootFolder){ Try { $ErrorActionPreference = "Stop" Get-ChildItem $RootFolder -recurse -Force | where{$_.psiscontainer} | ForEach-Object { $ifolders ++ Write-Progress -Activity "Counting Folders" -Status "Counting" -CurrentOperation "Count: $ifolders - Name: $_.Fullname" } } Catch { $DateTime = (Get-Date).ToShortDateString() + " " + (Get-Date).ToShortTimeString() $Target = $_.TargetObject $e = $_ Add-Content -Path $ErrorLog -Value "$DateTime - $e $Target" Write-Host "$e $Target" $ErrorActionPreference = "Continue" } } Else{ Write-Host "Path not found: $RootFolder." } Write-Host "`nScript complete."

which you call the continue statement carefully, as it is on error easy to create an infinite loop. Example Count to 10 but miss out the number 5: PS> $i =0 while ($i -lt 10) { $i +=1 if ($i powershell try catch -eq 5) {continue} Write-Host $i } “Just don't give up trying to do what you really want to do.

PowerShell -ErrorAction SilentlyContinue If a PowerShell script halts, or a portion of the code does not work, what action do you want the error to trigger? One popular solution is to tell the script to silently continue.Windows PowerShell -ErrorAction SilentlyContinue -ErrorAction Example: Check If a Service Has Been Installed Problems With Stop-Process Problems Displaying Registry Hives Research -ErrorAction Stop ♣ -ErrorAction Example: Check If a Service Has Been Installed # PowerShell -ErrorAction SilentlyContinue example Clear-Host $SrvName = "Printer Spooler"$Service = Get-Service -display $SrvName -ErrorAction SilentlyContinue if (-Not $Service) {$SrvName + " is NOT installed check the name."} else {$SrvName + " is installed." $SrvName + "'s status is: " + $service.Status } Note 1: While this example shows -ErrorAction, you must decide if it's better than the built-in message ObjectNotFound.Action Point remove -ErrorAction SilentlyContinue from the above script. Note 2: The actual name of this service is Print Spooler (not Printer). I made this deliberate mistake so as to create the error message. Problems With Stop-Process Scenario you create a PowerShell script which will kill several processes. The problem arises when the first process does not exist, consequently the script comes to a halt prematurely. "Cannot find a process with the process identifier 5132" Zapping processes is a classic job for SilentlyContinue ... provided you know what you're doing! If you would like to try this for real, then launch Task Manager and note the PID (process ID) of one real and two fictitious processes. Then substitute your PIDs for 5132, 5075, 5072 in my script below. # PowerShell SilentlyContinueClear-HostStop-Process 5132, 5075, 5072 -ErrorAction SilentlyContinue Note 3: Please don't use Stop-Process unless you understand what you are doing, for instance, you make a 'walk-though' of stopping the process with task manager. Guy Recommends: Free WMI Monitor for PowerShell Windows Management Instrumentation (WMI) is one of the hidden treasures of Microsoft's operating systems. Fortunately, SolarWinds have created a Free WMI Monitor so that you can discover these gems of performance information, and thus improve your PowerShell scripts. Take the guess work out of which WMI counters to use when scripting the operating system, Active Directory, or Exchange Server. Give this WMI monitor a try - it's free. Downloa
