Downloading files from the Internet using Powershell with progress - http

Question

I have been working on a powershell script that uses a .txt file to download multiple files from tinyurls. I have been successful in using Jobs to make this happen simultaneously, thanks to those on this forum.
The project requires some pretty large files to be downloaded, and using the current method has no progress indicator. I figured some users might think the program died. Looking for a way give a status of where it is in the download. Here is what I came up with, but I'm lost in how to pipe this information back out to the console. Any suggestions?
#Checks to see if NT-Download folder is on the Desktop, if not found, creates it
$DOCDIR = [Environment]::GetFolderPath("Desktop")
$TARGETDIR = "$DOCDIR\NT-Download"
if(!(Test-Path -Path $TARGETDIR )){
New-Item -ItemType directory -Path $TARGETDIR
}
$filepaths = Resolve-Path "files.txt"
Get-Content "$filepaths" | Foreach {
Start-Job {
function Save-TinyUrlFile
{
PARAM (
$TinyUrl,
$DestinationFolder
)
$response = Invoke-WebRequest -Uri $TinyUrl
$filename = [System.IO.Path]::GetFileName($response.BaseResponse.ResponseUri.OriginalString)
$filepath = [System.IO.Path]::Combine($DestinationFolder, $filename)
$totalLength = [System.Math]::Floor($response.get_ContentLength()/1024)
$responseStream = $response.GetResponseStream()
$buffer = new-object byte[] 10KB
$count = $responseStream.Read($buffer,0,$buffer.length)
$downloadedBytes = $count
try
{
$filestream = [System.IO.File]::Create($filepath)
$response.RawContentStream.WriteTo($filestream)
$filestream.Close()
while ($count -gt 0)
{
[System.Console]::CursorLeft = 0
[System.Console]::Write("Downloaded {0}K of {1}K", [System.Math]::Floor($downloadedBytes/1024), $totalLength)
$targetStream.Write($buffer, 0, $count)
$count = $responseStream.Read($buffer,0,$buffer.length)
$downloadedBytes = $downloadedBytes + $count
}
"`nFinished Download"
$targetStream.Flush()
$targetStream.Close()
$targetStream.Dispose()
$responseStream.Dispose()
}
finally
{
if ($filestream)
{
$filestream.Dispose();
}
}
}
Save-TinyUrlFile -TinyUrl $args[0] -DestinationFolder $args[1]
} -ArgumentList $_, "$TARGETDIR"
}

Answer 1

Have a look at Write-Progress
PS C:> for ($i = 1; $i -le 100; $i++ )
{write-progress -activity "Search in Progress" -status "$i% Complete:" -percentcomplete $i;}

Answer 2

Far more simple way : rely on Bits:
Start-BitsTransfer -Source $tinyUrl
