Help creating a log with Powershell

Hello Powershell experts,

I have the following code to move all the files in a folder called source to a different folder called target:

Get-ChildItem -Path "c:\source"  | select name | Move-Item -Destination "c:\target"

This works as expected.  Now I would like the name of each file moved written to a text file.  I'm not sure how to do this.  My initial thought was something like:

Get-ChildItem -Path "c:\source"  | select name | Move-Item -Destination "c:\target" | foreach-object {write-host "$_.name moved successfully" >> c:\movereport.txt}

This didn't work.  How would I accomplish this?

Thanks,
Nick

There were several issues with your command.
* When you're inside a string and you want to access an object's property (as in "$_.Name moved ..."), you need to use "$($_.Name) moved ...", otherwise the parser will evaluate that to "$_" and the string ".Name moved ....".
* "Write-Host", as its name implies, sends the pipeline output to the Powershell host (that is, the console), and that's where the output stops. Output sent to Write-Host will not be passed further down the pipeline. Just pass the string, or if you want to be explicit about sending it down the pipeline, pipe it to "Write-Output".
Get-ChildItem -Path "C:\Source" | ForEach-Object {
	Move-Item $_.FullName -Destination "C:\Target" -ErrorAction SilentlyContinue
	If ($?) {
		$Result = "Success"
		$Color = [ConsoleColor]::Green
	} Else {
		$Result = "Error"
		$Color = [ConsoleColor]::Red
	}
	"$($_.Name): $($Result)" | Write-Host -ForegroundColor $Color
	"$($_.Name): $($Result)" >> c:\movereport.txt
}

Or instead of using the redirection, you can use Add-Content with -PassThru instead of lines 10 and 11:
"$($_.Name): $($Result)" | Add-Content -Path "c:\movereport.txt" -PassThru | Write-Host -ForegroundColor $Color

Powershell 3.0 and later has the "Tee-Object" cmdlet that can send pipeline output to file and then pass it further down the pipeline; with that, you could use this instead of lines 10 and 11:
"$($_.Name): $($Result)" | Tee-Object -FilePath "c:\movereport.txt" -Append | Write-Host -ForegroundColor $Color

becraig,
Move-Item doesn't throw an exception when it can't move a file, it just errors out. You either need to check $?, or use -ErrorAction Stop.

Thanks I was actually planning to rewrite with an error.clear at the start of each move and then use if/else to check error condition after the move writing the exception to the log.

What is the "$?" ?

That's a (boolean) default variable that is $True if the last cmdlet executed without error, $False otherwise.
Get-Item $ENV:SystemRoot | Out-Null; "Got a known item; expected result is True: " + $?
Get-Item ".\asd.fgh" -ea si; "Created an error; expected result is False: " + $?
