So, I'm finished with downloading Ubuntu 12.04 torrent. I used rtorrent for that. After it's finished, I closed the rtorrent. Now, I still has the torrent file and I want to seed it without redownloading the iso file.

How can I accomplish that with a command line program? uTorrent can do this kind of thing easily, but I want a simple command line.

I tried rtorrent as well as aria2c, both didn't work out my purpose.

You do it with exactly the same command that you started the torrent download with. This means you still need to have the .torrent file handy.

This works because the bittorrent client does a hash check of the downloaded data, recognizes that the download is complete, and automatically starts uploading, correct? – xdumaine Jul 23 '12 at 1:08
    
That's right. :) – Michael Hampton Jul 23 '12 at 1:10
    
Actually, it works! I forgot to ignore the rtorrent unfriendly-seed-config. But aria2c prompted to redownload and overwrite the downloaded data before it can seed the torrent. – pepito Jul 23 '12 at 9:35
    
Simply adding a session directory to rtorrent is the very 1st thing to do when setting it up, and makes the whole thing a non-issue. – pyroscope Jul 23 '12 at 18:34
    
All right, thanks. I'll read about rtorrent session things. – pepito Jul 24 '12 at 11:35
