<h2>NAME</h2>
|
|
<div class="sectionbody">
|
|
<p>aria2c - The ultra fast download utility</p>
|
|
</div>
|
|
<h2>SYNOPSIS</h2>
|
|
<div class="sectionbody">
|
|
<p>aria2c [<em>OPTIONS</em>] [<em>URL</em> | <em>TORRENT_FILE</em> | <em>METALINK_FILE</em>]…</p>
|
|
</div>
|
|
<h2>DESCRIPTION</h2>
|
|
<div class="sectionbody">
|
|
<p>aria2 is a utility for downloading files. The supported protocols are HTTP(S), FTP, BitTorrent, and Metalink. It has a powerful segmented downloading ability, downloading a file from multiple sources and multiple protocols and utilizing your download bandwidth to the maximum. It supports downloading a file from HTTP(S)/FTP and BitTorrent at the same time, while the data downloaded from HTTP(S)/FTP is uploaded to the BitTorrent swarm. Using Metalink's chunk checksums, aria2 automatically validates chunks of data while downloading a file like BitTorrent.</p>

<h3>URL, TORRENT_FILE, METALINK_FILE</h3>
|
|
<p>You can specify multiple URLs in command-line.
|
|
Unless you specify -Z option, all URLs must point to the same file or downloading will fail.</p>
|
|
<p>You can also specify arbitrary number of torrent files and metalink files
|
|
stored in a local drive. Please note that they are always treated as a
|
|
separate download.</p>
|
|
<p>You can specify both torrent file with -T option and URLs. By doing this,
|
|
download a file from both torrent swarm and HTTP(S)/FTP server at the same time,
|
|
while the data from HTTP(S)/FTP are uploaded to the torrent swarm. Note that
|
|
only single file torrent can be integrated with HTTP(S)/FTP.</p>

<h2>RESUME DOWNLOAD</h2>
|
|
<div class="sectionbody">
|
|
<p>Usually, you can resume transfer by just issuing same command(aria2c URL)
|
|
if the previous transfer is made by aria2.</p>
|
|
<p>If the previous transfer is made by a browser or wget like sequencial
|
|
download manager, then use -c option to continue the transfer(aria2c -c URL).</p>
|
|
</div>
|
|
<h2>CONTROL FILE</h2>
|
|
<div class="sectionbody">
|
|
<p>aria2 uses a control file to keep track the progress of download.
|
|
A control file is placed at the same directory of the dowloading file and
|
|
its filename is the filename of downloading file with ".aria2" appended.
|
|
For example, if you are downloading file.zip, then the control file should be
|
|
file.zip.aria2.
|
|
(There is a exception for this naming convention.
|
|
If you are downloading a multi torrent, its control file is the "top directory"
|
|
name of the torrent with ".aria2" appended.
|
|
The "top directory" name is a value of "name" key in "info" directory in a torrent file.)</p>
|
|
<p>Usually a control file is deleted once download completed.
|
|
If aria2 decides that download cannot be resumed(for example, when downloading
|
|
a file from a HTTP server which doesn't support resume), a control file is
|
|
not created.</p>
|
|
<p>Normally if you lose a control file, you cannot resume download.
|
|
But if you have a torrent or metalink with chunk checksums for the file,
|
|
you can resume the download without a control file by giving
|
|
—check-integrity=true option to aria2c in command-line.</p>
|
|
</div>
|
|
<h2>SEEDING DOWNLOADED FILE IN BITTORRENT</h2>

|
<div class="sectionbody">
