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.

OPTIONS
-------

Basic Options
~~~~~~~~~~~~~
-d, --dir=DIR::
  The directory to store the downloaded file.

-i, --input-file=FILE::
  Downloads URIs found in FILE. You can specify multiple URIs for a single
  entity: separate URIs on a single line using the TAB character.
  Reads input from stdin when '-' is specified.

-l, --log=LOG::
  The file name of the log file. If '-' is specified, log is written to
  stdout.

-j, --max-concurrent-downloads=N::
  Set maximum number of parallel downloads.
  Default: '1'

--check-integrity='true'|'false'::
  Check file integrity by validating piece hash.
  This option only affects in BitTorrent downloads and Metalink downloads with
  chunk checksums.
  Use this option to re-download a damaged portion of a file.
  Default: 'false'

-c, --continue::
   Continue downloading a partially downloaded file.
   Use this option to resume a download started by a web browser or another
   program which downloads files sequentially from the beginning.
   Currently this option is only applicable to HTTP(S)/FTP downloads.

-h, --help[=CATEGORY]::
  Print usage and exit.
  The help messages are classified in several categories.
  For example, type "--help=http" for detailed explanation for the options
  related to HTTP. If no matching category is found, search option name using
  a given word in forward match and print the result.
  Available Values: 'basic', 'advanced', 'http', 'ftp', 'metalink',
  'bittorrent', 'all'
  Default: 'basic'

HTTP/FTP Options
~~~~~~~~~~~~~~~~
--lowest-speed-limit=SPEED::
  Close connection if download speed is lower than or equal to this
  value(bytes per sec).
  '0' means aria2 does not have a lowest speed limit.

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.

Encrypt whole payload using ARC4:
-------------------------------------------------------------------------
aria2c --bt-min-crypto-level=arc4 --bt-require-crypto=true file.torrent
-------------------------------------------------------------------------

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
---------------------------------------------

FILES
-----
aria2.conf
~~~~~~~~~~
User configuration file.
It must be placed under $HOME/.aria2 and must be named as aria2.conf.
In each line, there is 1 parameter whose syntax is name=value pair,
where name is the long command-line option name without '--' prefix.
The lines beginning '#' are treated as comments.

--------------------------------------
# sample configuration file for aria2c
listen-port=60000
dht-listen-port=60000
seed-ratio=1.0
max-upload-limit=50K
ftp-pasv=true
--------------------------------------

dht.dat
~~~~~~~~
The routing table of DHT is saved to the path $HOME/.aria2/dht.dat.
