I wanted to get up and running with a VirtualBox-hosted VM for testing out IE9 at work. Microsoft kindly provides testing environments for various VM hosts on the major platforms to do so. The VM image is broken in to chunks of RAR files and listed in a plaintext index so I figured wget with the -i switch was the way to go:
$ wget -i https://az412801.vo.msecnd.net/vhd/VMBuild_20131127/VirtualBox/IE9_Win7/Linux/IE9.Win7.For.LinuxVirtualBox.txt
The only problem is that this maxed out the downlink for the office. wget does provide rate-limiting, and picking up where it left off on a previous download attempt so I wouldn't have to re-download the previous chunks:
$ wget --limit-rate=500k -c -i https://az412801.vo.msecnd.net/vhd/VMBuild_20131127/VirtualBox/IE9_Win7/Linux/IE9.Win7.For.LinuxVirtualBox.txt
Happy downloading! :)
