Downloading Torrent Files via the Linux Terminal

On my post entitled "How to use BitTorrent in Linux" I've taught you the basics of downloading torrent files using Transmission, a popular BitTorrent client with GUI (Graphical User Interface). This time, I will show you how to use an ultra-lightweight text-based ncurses BitTorrent client --rTorrent.

I know downloading torrent files via the Linux terminal sounds exciting so here we go...

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. Let's say you got a file named free.torrent and saved it on the Desktop. You can download it through this command:

$ rtorrent Desktop/free.torrent

The downloads (finished and unfinished) will be saved at /home/username by default.

That would be enough to get you downloading torrent files via the Linux terminal in no time. But if you want to learn some of the more advanced features of rTorrent, don't rely on its man page because you will be disappointed. Instead, use this cheat sheet:

Adding and removing torrents
Backspace -- Add torrent using an URL or file path. Use tab to view directory content and do auto-complete. Also, wildcards can be used. For example: ~/torrent/*
Return/Enter -- Same as backspace, except the torrent remains inactive. (Use ^s to activate)
CTRL-O -- Set new download directory for selected torrent. Only works if torrent has not yet been activated.
CTRL-S -- Start download. Runs hash first unless already done.
CTRL-D -- Stop an active download, or remove a stopped download.
CTRL-R -- Initiate hash check of torrent. Without starting to download/upload.

Throttling
a/s/d -- Increase the upload throttle by 1/5/50 KB.
z/x/c -- Decrease the upload throttle by 1/5/50 KB.
A/S/D -- Increase the download throttle by 1/5/50 KB.
Z/X/C -- Decrease the download throttle by 1/5/50 KB.
