rtorrent is very useful if you want to download files in a shell. See e.g. tmux for a very useful scenario.

The basic use of rtorrent is very simple. Start rtorrent either with or without torrent files.

rtorrent [file/URL ...]

If you haven't supplied any torrent files at start up you can open a torrent file by pressing ENTER.

Inside rtorrent you may use UP/DN arrow keys to move between torrents. Use LE/RT arrow keys to get more information about a torrent.

Magnet links works fine in rtorrent 0.8.9 or later.
