aria2c - The high speed download utility

Synopsis

aria2c [options] URL ... aria2c [options] -T TORRENT_FILE FILE ... aria2c [options] -M METALINK_FILE

Description

aria2 is a utility for downloading files. It has completely new design concept from its predecessor, Aria, and is written from scratch. aria2 has a segmented downloading engine in its core. It can download one file from multiple URLs or multiple connections from one URL. This results in very high speed downloading, much faster than ordinary browsers. This engine in was implemented in a single-thread model. The architecture is clean and easy to extend. aria2 currently supports HTTP, FTP, and BitTorrent. It also supports Metalink version 3.0.

Options

-d, --dir=DIR The directory to store downloaded file.

-o, --out=FILE The file name for downloaded file.

-l, --log=LOG The file path to store log. If ‘-’ is specified, log is written to stdout.

-D, --daemon Run as daemon.

-s, --split=N Download a file using N connections. N must be between 1 and 5. This option affects all URLs. Thus, aria2 connects to each URL with N connections.

--retry-wait=SEC Set amount of time in second between requests for errors. Specify a value between 0 and 60. Default: 5

-t, --timeout=SEC Set timeout in second. Default: 60

-m, --max-tries=N Set number of tries. 0 means unlimited. Default: 5

--http-proxy=HOST:PORT Use HTTP proxy server. This affects to all URLs.

--http-user=USER Set HTTP user. This affects to all URLs.

--http-passwd=PASSWD Set HTTP password. This affects to all URLs.

--http-proxy-user=USER Set HTTP proxy user. This affects to all URLs

--lowest-speed-limit=SPEEDClose connection if download speed is lower than or equal to this value(bytes per sec). 0 means aria2 does not care lowest speed limit. You can append K or M(1K = 1024, 1M = 1024K). This option does not affect BitTorrent download. Default: 0

--max-download-limit=SPEED Set max download speed in bytes per sec. 0 means unrestricted. You can append K or M(1K = 1024, 1M = 1024K). Default: 0

-T, --torrent-file=TORRENT_FILE The file path to .torrent file.

--follow-torrent=true|falseSetting this option to false prevents aria2 to enter BitTorrent mode even if the filename of downloaded file ends with .torrent. Default: true

--direct-file-mapping=true|false Directly read from and write to each file mentioned in .torrent file. Default: true

--listen-port=PORT Set port number to listen to for peer connection.

--max-upload-limit=SPEED Set max upload speed in bytes per sec. 0 means unrestricted. You can append K or M(1K = 1024, 1M = 1024K). Default: 0

--select-file=INDEX... Set file to download by specifing its index. You can know file index through --show-files option. Multiple indexes can be specified by using ‘,’ like “3,6". You can also use ‘-’ to specify rangelike “1-5". ‘,’ and ‘-’ can be used together.

--seed-time=MINUTES Specify seeding time in minutes. See also --seed-ratio option.

--seed-ratio=RATIO Specify share ratio. Seed completed torrents until share ratio reaches RATIO. 1.0 is encouraged. If --seed-time option is specified along with this option, seeding ends when at least one of the conditions is satisfied.

-M, --metalink-file=METALINK_FILE The file path to .metalink file.

-C, --metalink-servers=NUM_SERVERS The number of servers to connect to simultaneously. If more than one connection per server is required, use -s option. Default: 15

--metalink-version=VERSION The version of file to download.

--metalink-language=LANGUAGE The language of file to download.

--metalink-os=OS The operating system the file is targeted.

--follow-metalink=true|falseSetting this option to false prevents aria2 to enter Metalink mode even if the filename of downloaded file ends with .metalink. Default: true

-v, --version Print the version number and exit.

-h, --help Print this message and exit.

URL You can specify multiple URLs. All URLs must point to the same file or downloading fails.

FILE Specify files in multi-file torrent to download. Use conjunction with -T option. This arguments are ignored if you specify --select-file option.
