我在风中等你

When running a simple PowerShell script from Task Scheduler, I would like to redirect the output to a file.

There is a long thread about this very topic here, yet i

Here is the command that worked for me. I didn't like the idea of redirecting the output in the script, since it would make it difficult to run manually.
```
powershell -windowstyle minimized -c "powershell -c .\myscript.ps1 -verbose >> \\server\myscript.log 2>&1"
```

I use the transcript feature to help with this. Just include it in your code and it outputs all (would be) screen content to a log file.
```
    Start-Transcript -path $LogFile -append

    <Body of the script>

    Stop-Transcript
```

I would do:
Create a function to call your script and redirect the output of this function like this:

.ps1:

function test{
    # Your simple script commands
    ls c:\temp -Filter *.JPG
    ls z:\ # Non-existent directory
}

test *> c:\temp\log.txt

Here is the log file:

    Répertoire : C:\temp


Mode                LastWriteTime     Length Name
----                -------------     ------ ----
-a---        07/06/2008     11:06     176275 HPIM1427.JPG
-a---        07/06/2008     11:06      69091 HPIM1428.JPG
-a---        07/06/2008     11:06     174661 HPIM1429.JPG


ls : Lecteur introuvable. Il n'existe aucun lecteur nommé « z ».
Au caractère C:\temp\test.ps1:14 : 1
+ ls z:\ #non existent dir
+ ~~~~~~
    + CategoryInfo          : ObjectNotFound: (z:String) [Get-ChildItem], Driv
   eNotFoundException
    + FullyQualifiedErrorId : DriveNotFound,Microsoft.PowerShell.Commands.GetC
   hildItemCommand

You can control what do you want to output with the new V3 redirection operators:

Do-Something 3> warning.txt  # Writes warning output to warning.txt
Do-Something 4>> verbose.txt # Appends verbose.txt with the verbose output
Do-Something 5>&1            # Writes debug output to the output stream
Do-Something *> out.txt      # Redirects all streams (output, error, warning, verbose, and debug) to out.txt
