A piece of my work around PowerShell and IIS (or usefull things I've found on the web). Mostly some reminders for myself!

Thanks to Jason Niver on MSDN Blogs (Downloading files from the internet in PowerShell (with progress)), yep, we can download a file from the web and display progress (bytes and percentage).

 

Function Get-Webfile ($url)
{
$dest=(Join-Path $pwd.Path $url.SubString($url.LastIndexOf('/')))
Write-Host "Downloading $url`n" -ForegroundColor DarkGreen;
$uri=New-Object "System.Uri" "$url"
$request=[System.Net.HttpWebRequest]::Create($uri)
$request.set_Timeout(5000)
$response=$request.GetResponse()
$totalLength=[System.Math]::Floor($response.get_ContentLength()/1024)
$length=$response.get_ContentLength()
$responseStream=$response.GetResponseStream()
$destStream=New-Object -TypeName System.IO.FileStream -ArgumentList $dest, Create
$buffer=New-Object byte[] 10KB
$count=$responseStream.Read($buffer,0,$buffer.length)
$downloadedBytes=$count
while ($count -gt 0)
{
[System.Console]::CursorLeft=0
[System.Console]::Write("Downloaded {0}K of {1}K ({2}%)", [System.Math]::Floor($downloadedBytes/1024), $totalLength, [System.Math]::Round(($downloadedBytes / $length) * 100,0))
$destStream.Write($buffer, 0, $count)
$count=$responseStream.Read($buffer,0,$buffer.length)
$downloadedBytes+=$count
}
Write-Host ""
Write-Host "`nDownload of `"$dest`" finished." -ForegroundColor DarkGreen;
$destStream.Flush()
$destStream.Close()
$destStream.Dispose()
$responseStream.Dispose()
}

You are absolutely right! And I missed to quote my source… It’s done now
