macos - How to download parts of the same file from different sources with curl/wget?

I have a quite large file hosted on five different servers.

I would like to be able to download different parts of the file from each server and subsequently concatenate the parts, in order to produce the original file.

Is there any way to do this with curl/wget or any other OS X command-line tools?

Answer

aria2 is the solution for multiple downloads of same file from different locations

http://aria2.sourceforge.net/

in your case : aria2c -s5 host1/bigfile host2/bigfile ... host5/bigfile

better late than never...
