Necesito descargar una serie del canal 9 usando powershell, sin embargo, los scripts que he probado tienen errores:
Este guion
$url="https://channel9.msdn.com/blogs/OfficeDevPnP/feed/mp4high" $rss=invoke-webrequest -uri $url $destination="D:\Videos\OfficePnP" [xml]$rss.Content|foreach{ $_.SelectNodes("rss/channel/item/enclosure") }|foreach{ "Checking $($_.url.split("/")[-1]), we will skip it if it already exists in $($destination)" if(!(test-path ($destination + $_.url.split("/")[-1]))){ "Downloading: " + $_.url start-bitstransfer $_.url $destination } }
falló con error:
