aria2 1.31

Download files/ torrents from the command line



Aria2 is an open source command line tool which can download files using various protocols (HTTP, HTTPS, FTP, BitTorrent, Metalink).

Don't be put off by "command line" - aria2 isn't difficult to use. At a minimum, you can download files just by entering their URL, like aria2c

If you'd like to take more control, though, aria2 has a vast number of optional commands. Would you like to download a file via multiple connections? Validate a download to check its integrity? Resume an interrupted download, throttle your download speed, set a user name/ password for authentication? It's all here, and the torrent support is particularly impressive (DHT, PEX, Encryption, Magnet URI, Web-Seeding, Selective Downloads, Local Peer Discovery and UDP tracker).

These commands may be combined, sometimes with impressive results: the program can download the same file in separate chunks from HTTP and FTP servers, while uploading everything you've got so far to a BitTorrent swarm.

But again, don't be put off by any apparent complexity. There are simpler features, too. Point aria2 at a text file containing URLs, for example, and it'll read, download and save them all: very convenient.

Release Note

This release fixes assertion error in
SimpleRandomizer::getRandomBytes. It adds new option


Better error message when local file status cannot be retrieved


Fix assertion failure in SimpleRandomizer::getRandomBytes

errno might not be initialized to 0, and we may get both rv == -1
and errno != ENOSYS. This leads to assertion failure. Since
getrandom_linux always returns -1 on failure, checking errno is
useless in this function.


Add option content-disposition-default-utf8
