how do I merge a pre-defined drive letter variable with the contects of a text file called using get-content?

Question

Hi, I'm struggling with the correct way to concatenate a pre-defined variable with the contents of a text file pulled from GC.variable:
$DriveLetter = ($MountResult | Get-Disk | Get-Partition).DriveLetter

merged with each line contained within:
$List = (Get-Content "C:\scripts\UPD_cleanup.txt")

\appdata\local\temp*
\AppData\Roaming\Mozilla\Firefox\Crash Reports
\AppData\Local\Microsoft\WebCache.old

to end up with:
G:\appdata\local\temp*
G:\AppData\Roaming\Mozilla\Firefox\Crash Reports
G:\AppData\Local\Microsoft\WebCache.old etc.

I tried a few things including:

$List = ($DriveLetter + ":")+(Get-Content "C:\scripts\UPD_cleanup.txt")

but it only worked for the first entry.

Thanks,

Brad

Hi @B Hodgins ,

You can try this

$List = Get-Content "C:\scripts\UPD_cleanup.txt" | ForEach-Object {  
    $DriveLetter + ":" + $_  
}

Thank you Ian. I tried you suggestion and at first it didn't work, then I realized that I was using get-content instead of get-childitem on the delete line. Once I changed that, everything started working. Not sure if it is the most efficient code or not, but at least I see results now:

                    $Logfile = "C:\scripts\removal_logfile3.txt"
                    Start-Transcript $Logfile -Append

                         $List = Get-Content "C:\scripts\Profile_cleanup.txt" | ForEach-Object {
                            $DriveLetter + ":" + $_
                                 }

                    get-childitem -path $List | Remove-Item -Force -Recurse -Confirm:$false -ErrorAction SilentlyContinue -verbose
                    Stop-Transcript

Hi @B Hodgins ,

You may try robocopy. It should be much faster.
