This post is not a review of aria2 (maybe I'll do one some day), rather it focuses on one of its features which has bugged me for a while.
aria2 can — among other things — be used to download torrents. You just pass a torrent file or a URL pointing to one, to
aria2c (the actual name of the binary) and it starts downloading the torrent contents.
But, I use rtorrent to download torrents, and just want to download the .torrent file with aria2. But, since aria2 simply starts downloading the torrent contents instead of just the file, I was forced to use wget for downloading the file.
Even after searching all over the internet, I couldn't find a way to do so with aria2.
