NAME
 | 
						|
----
 | 
						|
aria2c - The ultra fast download utility
 | 
						|
 | 
						|
SYNOPSIS
 | 
						|
--------
 | 
						|
aria2c ['OPTIONS'] ['URL' | 'TORRENT_FILE' | 'METALINK_FILE']...
 | 
						|
 | 
						|
DESCRIPTION
 | 
						|
-----------
 | 
						|
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.
 | 
						|

URL, TORRENT_FILE, METALINK_FILE
 | 
						|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 | 
						|
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.
 | 
						|
 | 
						|
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.
 | 
						|
 | 
						|
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.
 | 
						|
 | 
						|
[NOTE]
 | 
						|
Make sure that URL is quoted with single(\') or double(") quotation if it
 | 
						|
contains "&" or any characters that have special meaning in shell.

 | 
						|
-------------------------------------------------------------------------
 | 
						|
 | 
						|
RESUME DOWNLOAD
 | 
						|
---------------
 | 
						|
Usually, you can resume transfer by just issuing same command(aria2c URL)
 | 
						|
if the previous transfer is made by aria2.
 | 
						|
 | 
						|
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).
 | 
						|
 | 
						|
CONTROL FILE
 | 
						|
------------
 | 
						|
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.)
 | 
						|
 | 
						|
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.
 | 
						|
 | 
						|
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.
 | 
						|
 | 
						|
SEEDING DOWNLOADED FILE IN BITTORRENT
 | 
						|
-------------------------------------
 | 
						|
You can seed downloaded file using --check-integrity=true option.
 | 
						|
---------------------------------------------
 | 
						|
aria2c --check-integrity=true file.torrent
 | 
						|
---------------------------------------------
 | 
						|
 | 
						|
