When you download files from the internet and use PowerShell, you may want to find out how long the download will take. While you can check the size of the already downloaded binaries, to calculate a progress percentage you also know the size of the total download.
Here is a quick way of finding out the size of a file:
function Get-DownloadSize { [CmdletBinding()] param ( [Parameter(Mandatory,ValueFromPipeline)] [String] $Url ) process { $webRequest = [System.Net.WebRequest]::Create($Url) $response = $webRequest.GetResponse() $response.ContentLength $response.Dispose() } }
And this is an example:
PS> "https://github.com/PowerShell/PowerShell/releases/download/v6.2.1/PowerShell-6.2.1-win-x64.zip" | Get-DownloadSize 58716786
