How to download torrent files from command line(Linux Terminal)

This can be achieved by using the ultra-lightweight text-based BitTorrent client "rTorrent".
If you are using Ubuntu, you can install rTorrent via Synaptic Package Manager, or with this command:

$ sudo apt-get install rtorrent

You can also get rTorrent HERE.

Now, we will start using rTorrent. But first, download a '.torrent' file. You can download it through this command:

$ rtorrent  filename.torrent

By default the downloads (finished and unfinished) will be saved in your home directory.
