PoshTip #7 – How to retrieve a file from a given URL

You can use Invoke-WebRequest to download files.

First method

To simply download a file through HTTP, you can use this command

wget "http://technet.microsoft.com/" -OutFile "C:\out.html"

1	wget "http://technet.microsoft.com/" -OutFile "C:\out.html"

wget is an alias for Invoke-WebRequest

Invoke-WebRequest -Uri "http://technet.microsoft.com" -OutFile "C:\out.html"

1	Invoke-WebRequest -Uri "http://technet.microsoft.com" -OutFile "C:\out.html"

If the web server requires authentication, you have to use the -Credential parameter

Second method

Use the .NET WebClient object

$WebClient = New-Object System.Net.WebClient
$WebClient.DownloadFile("http://technet.microsoft.com/","C:\out.html")

1 2	$WebClient = New-Object System.Net.WebClient $WebClient.DownloadFile("http://technet.microsoft.com/","C:\out.html")
