rtorrent 文本方式的bt下载工具

rtorrent是一个字符界面的bt客户端，安装简便，而且速度也不错。

在ubuntu下使用下面的命令安装：
sudo apt-get install rtorrent

安装完成后我们需要作一些配置工作，配置文件是安装用户家目录下的.rtorrent.rc。这个文件默认是没有的，请到http: //libtorrent.rakshasa.no/browser/trunk/rtorrent/doc/rtorrent.rc?rev=latest 页面,将示例的配置文件内容拷贝粘贴到.rtorrent.rc中,然后我们来编辑它。
我将如下项的注释去掉，并按照自己的情况进行修改。

# Default directory to save the downloaded torrents.
directory =/home/lynn/bt
directory指定了下载文件的存放目录。

# Default session directory. Make sure you don't run multiple instance
# of rtorrent using the same session directory. Perhaps using a
# relative path?
session =/home/lynn/bt/session
session指定session的存放目录，有了它就能进行恢复下载。不然每次重启都要手动添加。

# Watch a directory for new torrents, and stop those that have been
# deleted.
schedule = watch_directory,5,5,load_start=/home/lynn/bt/watch/*.torrent
schedule = untied_directory,5,5,stop_untied=
这两项启动了rtorrent的监视功能，将种子文件放入load_start指定的目录中后，rtorrent将自动开始下载。

我的locale是zh_CN.UTF-8的因此我在配置文件中添加了下面一行，这样生成的目录和文件名就不是乱码了。
encoding_list=UTF-8

具体的操作请看man。
