I am using the following command line to download the serverfiles(debian jessie):
wget -O ~/newserver.tar "http://download.rising-world.net/download.php?type=server&filetype=tar"
The "-O" should do the magic thing .. saving the connected link data into newserver.tar file.
There may be other types of archieves but at the moment those tar archieves works well enough.
You could use a script like(maybe it works ONLY using debian jessie):
I still use the mc (midnightcommander) to extract and copy the files manually.. IF I ever have plenty of time.. i would like to rewrite the script for automatism
