Powershell - how to log for each object-CodePudding

I'm slowly getting to grips with Powershell but I cant see how to capture the for-each loop in a log (its probably something straight forward). My current code creates the log but doesnt seem to write to it - any ideas where I am going wrong?

$CSVImp = Import-Csv -Path "C:\Support\Powershell-Rename\Data.csv" 
$OutputLog = ".\output.log" 
Write $CSVImp | Where-Object { $_.CompName -eq $env:computername } | ForEach-Object {Rename-Item $_.FileLocation -NewName $_.FileRename -ErrorAction SilentlyContinue } | Out-File $OutputLog -Append

Thanks

The scriptblock you pass to ForEach-Object can have as many statements as you like:

... |ForEach-Object {
    Rename-Item $_.FileLocation -NewName $_.FileRename -ErrorAction SilentlyContinue 
    if($?){
        "[ ] Successfully renamed '$($_.FileLocation)' to '$($_.FileRename)'"
    }
    else {
        "[!] Failed to rename '$($_.FileLocation)' to '$($_.FileRename)'"
    }
} |Out-File $OutputLog -Append

I'd suggest something like this where you use a Try/Catch block to log your entries.

$CSVImp = Import-Csv -Path "C:\Support\Powershell-Rename\Data.csv" 
$OutputLog = ".\output.log" 
$CSVImp | Where-Object { $_.CompName -eq $env:computername } | 
          ForEach-Object {
            Try {
                  Rename-Item $_.FileLocation -NewName $_.FileRename -ErrorAction Stop 
                  "Success: Rename $($_.FileLocation) to $($_.FileRename)" | 
                       Out-File $OutputLog -Append
            }
            Catch {
             "Failed:  Renamed $($_.FileLocation) to $($_.FileRename)" | 
                Out-File $OutputLog -Append
            }
