Usage

Overview

This manual page documents briefly the btdownloadheadless, btdownloadcurses, and btdownloadgui commands. This manual page was written for the Debian distribution because the original program does not have a manual page.

These are all programs that allow a user to download files using bittorrent, a peer to peer, scatter-gather network protocol. They all have the same options.

Options

These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.

--responsefile filename

treat filename as a file which the server response was stored in. If this option is used, no filename or URL should be present on the command line.

--url url

retrieve the torrent info file from url. If this option is used, no filename or URL should be present on the command line.

-i ip | --ip ip

report ip as your IP to the tracker

--bind ip

bind to ip instead of the default

--minport portnum

set portnum as the minimum port to listen on, counts up if unavailable (default 6881)

--maxport portnum

set portnum as the maximum port to listen on (default 6889)

--saveas filename

store the downloaded file to filename, instead of querying user (gui) or using the filename stored in the torrent info file

--request_backlog num
