aria2c :- Utility for Downloading files

aria2 is a utility for downloading files.

The supported protocols are HTTP(S), FTP, BitTorrent and Metalink. It has a powerful segmented
downloading ability, downloading a file from multiple sources and multiple protocols and utilizing
your download bandwidth to the maximum. 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
Metalinks chunk checksums, aria2 automatically validates chunks of data while downloading a file like BitTorrent.
