On Windows, there are plenty download manager to download and resume. But on Linux, I could not find any yet until today. I used aria2 to resume and segmented the download. It supports HTTP, HTTPS, FTP and BitTorrent.

I am using Ubuntu, so just type in the following command into the terminal.

sudo apt-get install aria2

But something I still not very satisfy is it does not have any GTK+ interface! The only thing maybe I can please of it is the low processor consumption. It runs on single thread model. The memory usage is just like 3MB for HTTP download and 5MB for BitTorrent.

Some useful command:

Simple download

aria2c http://AAA.BBB.CCC/file.zip

Download from different servers

aria2c http://AAA.BBB.CCC/file.zip http://DDD.EEE.FFF/GGG/file.zip

Download from BitTorrent

aria2c -o test.torrent http://AAA.BBB.CCC/file.torrent
