FTPS Upload in Powershell
<p>I'm in the process of learning Powershell, and am working on a little script that will upload a group of files to an FTPS server nightly. The files are located on a network share in a sub-directory containing the date in the name. The files themselves will all begin with the same string, let's say "JONES_". I have this script working for FTP, but I don't quite get what I need to do to get it to work for FTPS:</p>

<pre><code># Set yesterday's date (since uploads will happen at 2am)
$YDate = (Get-Date).AddDays(-1).ToString('MM-dd-yyyy')

#Create Log File
$Logfile = "C:\powershell\$YDate.log"
Function LogWrite
{
    Param ([string]$logstring)

    Add-Content $Logfile -value $logstring
}


# Find Directory w/ Yesterday's Date in name
$YesterdayFolder = Get-ChildItem -Path "\\network\storage\location" | Where-Object {$_.FullName.contains($YDate)}


If ($YesterdayFolder) {

    #we specify the directory where all files that we want to upload are contained 
    $Dir= $YesterdayFolder
    #ftp server
    $ftp = "ftp://ftps.site.com"
    $user = "USERNAME"
    $pass = "PASSWORD"

    $webclient = New-Object System.Net.WebClient 
    $webclient.Credentials = New-Object System.Net.NetworkCredential($user,$pass)


$FilesToUpload = Get-ChildItem -Path (Join-Path $YesterdayFolder.FullName "Report") | Where-Object {$_.Name.StartsWith("JONES","CurrentCultureIgnoreCase")}
foreach($item in ($FilesToUpload))
    { 
        LogWrite "Uploading file:  $YesterdayFolder\Report\$item"
        $uri = New-Object System.Uri($ftp+$item.Name) 
        $webclient.UploadFile($uri, $item.FullName)  
    }
    } Else {
        LogWrite "No files to upload"
    }
</code></pre>

<p>I'd rather not have to deal with a 3rd party software solution, if at all possible. </p>
