Anyway, I'd prefer using substring to make the code more readable :D [code] HttpURLConnection.followRedirects=false def vid=args[0].substring('http://www.youtube.com/watch?v='.length()) def uri = new URL("http://www.youtube.com/v/$vid").openConnection().getHeaderField('Location') def t=uri.substring(uri.lastIndexOf('=')+1) HttpURLConnection.followRedirects=true def output=new File("${vid}.flv") if(output.exists()) output.delete() println "Saving ${output.canonicalPath}" output.withOutputStream{os -> new URL("http://www.youtube.com/get_video?video_id=$vid&t=$t").eachByte{os.write(it)}} [/code] Awesome!

[code]
HttpURLConnection.followRedirects=false
def vid=args[0].substring('http://www.youtube.com/watch?v='.length())
def uri = new URL("http://www.youtube.com/v/$vid").openConnection().getHeaderField('Location')
def t=uri.substring(uri.lastIndexOf('=')+1)
HttpURLConnection.followRedirects=true
def output=new File("${vid}.flv")
if(output.exists()) output.delete()
println "Saving ${output.canonicalPath}"
output.withOutputStream{os -> new URL("http://www.youtube.com/get_video?video_id=$vid&t=$t").eachByte{os.write(it)}}
[/code]
