aria2

aria2 is a utility for downloading files.

aria2 can download a file from multiple sources/protocols and tries to use the maximum download bandwidth. It 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.
