Aria2 – high speed command line download utility in Debian

aria2 is a utility for downloading files. The supported protocols are HTTP(S), FTP, BitTorrent (DHT, PEX, MSE/PE), and Metalink. It can download a file from multiple sources/protocols and tries to utilize your maximum download bandwidth.

It even supports downloading a file from HTTP(S)/FTP and BitTorrent at the same time, while the data downloaded from HTTP(S)/FTP is uploaded to the BitTorrent swarm. Using Metalink’s chunk checksums, aria2 automatically validates chunks of data while downloading a file like BitTorrent.
