ps1 script using stream redirection works from cmd.exe but not from Task Scheduler

    Hello running 2008 R2

    I have a basic script “CleanDisk.ps1” that deletes some files older then x days

    # Clearing logs

    $Path = "D:\mylogs\logs"

    $Daysback = "-14"

    $CurrentDate = Get-Date

    $DatetoDelete = $CurrentDate.AddDays($Daysback)

    Get-ChildItem $Path -recurse | Where-Object { $_.LastWriteTime -lt $DatetoDelete} | Remove-Item -recurse -force -verbose

     

     Taking a tip from this post (could not really tell if 4>&1 was fully implemented or not)

    http://connect.microsoft.com/PowerShell/feedback/details/297055/capture-warning-verbose-debug-and-host-output-via-alternate-streams

     

    I test the script from cmd.exe like so

    powershell.exe -command "D:\Scripts\CleanDisk.ps1" 4>&1 > "D:\Scripts\logs\clean_logs.log"

    This runs as expected and writes verbose info to the log

    VERBOSE: Performing operation "Remove File" on Target "D:\logs\do_submit_08JUN11124843.log"

     

    When I schedule this same exact script with Task Scheduler it does not work as expected.  Task Scheduler says it completes without error but it does not delete the files or write to the log.  Appears something this wrong with the stream or my user error.  Still new to this.

    In my setup Program/script:

    powershell.exe

    Add arguments (Optional):

    -command "D:\BRM\Scripts\CleanDisk.ps1" 4>&1 > "D:\Scripts\logs\clean_logs.log"

     

    When I schedule the script with just  2>&1 it works but I do not get any verbose information on the files that were deleted.  

    Help/Insight but appreciated.

    Thanks

    Looks like you are trying to capture the output to a text file. If that is your requirement, I prefer using write-log powershell function in your script which works both from command prompt and from scheduled task.

    I feel this is the simple way.

    I am hoping for an easier way.  I am not sure how to use that function and how to implement it.

    If it works from the cmd line I am hoping there is a way to make it work scheduled.

    Hi,

    Try put this command to bat file and run from task scheduler this bat:

    powershell.exe -command "D:\Scripts\CleanDisk.ps1" 4>&1 > "D:\Scripts\logs\clean_logs.log"


    Or try use Start-Transcript / Stop-Transcript cmmandlets.

    Start-Transcript D:\Scripts\logs\clean_logs.log
    Get-ChildItem $Path -recurse | Where-Object { $_.LastWriteTime -lt $DatetoDelete} | Remove-Item -recurse -force -verbose
    Stop-Transcript


    Or try put writing to log in ps script like this:

    Get-ChildItem $Path -recurse | Where-Object { $_.LastWriteTime -lt $DatetoDelete} | %{Out-File -inputobject $_.FullName -Append D:\Scripts\logs\clean_logs.log; Remove-Item $_ -force }

    When scheduling with the -File parameter it works as expected...all output streams are written to the log

    powershell.exe -NoProfile -File D:\Scripts\CleanDisk.ps1 > D:\Scripts\logs\clean_logs.log

    I try this, I call ps1 file using parameters, and I need log all output to file, but it doesn't work.

    C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Unrestricted -WindowStyle Hidden -NoLogo -File "deploy.TemplateRemoteDeployScriptPS.ps1" Desarrollo DESIIS01 "Web" True True instalador passwd "C:\Tests\LifeCycle.IISDeploy" "LifeCycle.Deploy.Test.PowerShell" >C:\temp\resultadosDeploy.txt 2>&1

    it doesn`t work

    C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Unrestricted -WindowStyle Hidden -NoLogo -File "deploy.TemplateRemoteDeployScriptPS.ps1" Desarrollo DESIIS01 "Web" True True instalador passwd "C:\Tests\LifeCycle.IISDeploy" "LifeCycle.Deploy.Test.PowerShell" >C:\temp\resultadosDeploy.txt
