--netrc-path=FILE Specify the path to the netrc 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. Additionally, options can be specified after each line of URI. This optional line must start with one or more white spaces and have one option per single line. See INPUT FILE section of man page for details. See also --deferred-input option.

-j, --max-concurrent-downloads=N Set maximum number of parallel downloads for every static (HTTP/FTP) URL, torrent and metalink. See also --split and --optimize-concurrent-downloads options.

--optimize-concurrent-downloads[=true|false|A:B] Optimizes the number of concurrent downloads according to the bandwidth available. aria2 uses the download speed observed in the previous downloads to adapt the number of downloads launched in parallel according to the rule N = A + B Log10(speed in Mbps). The coefficients A and B can be customized in the option arguments with A and B separated by a colon. The default values (A=5,B=25) lead to using typically 5 parallel downloads on 1Mbps networks and above 50 on 100Mbps networks. The number of parallel downloads remains constrained under the maximum defined by the max-concurrent-downloads parameter.

--load-cookies=FILE Load Cookies from FILE using the Firefox3 format and Mozilla/Firefox(1.x/2.x)/Netscape format.

--save-cookies=FILE Save Cookies to FILE in Mozilla/Firefox(1.x/2.x)/ Netscape format. If FILE already exists, it is overwritten. Session Cookies are also saved and their expiry values are treated as 0.

-S, --show-files[=true|false] Print file listing of .torrent, .meta4 and .metalink file and exit. More detailed information will be listed in case of torrent file.

--select-file=INDEX... Set file to download by specifying its index. You can find the file index using the --show-files option. Multiple indexes can be specified by using ',', for example: "3,6". You can also use '-' to specify a range: "1-5". ',' and '-' can be used together. When used with the -M option, index may vary depending on the query(see --metalink-* options).

--follow-torrent=true|false|mem If true or mem is specified, when a file whose suffix is .torrent or content type is application/x-bittorrent is downloaded, aria2 parses it as a torrent file and downloads files mentioned in it. If mem is specified, a torrent file is not written to the disk, but is just kept in memory. If false is specified, the .torrent file is downloaded to the disk, but is not parsed as a torrent and its contents are not downloaded.

--listen-port=PORT... Set TCP port number for BitTorrent downloads. Multiple ports can be specified by using ',', for example: "6881,6885". You can also use '-' to specify a range: "6881-6999". ',' and '-' can be used together.

--max-overall-upload-limit=SPEED Set max overall upload speed in bytes/sec. 0 means unrestricted. You can append K or M(1K = 1024, 1M = 1024K). To limit the upload speed per torrent, use --max-upload-limit option.

-u, --max-upload-limit=SPEED Set max upload speed per each torrent in bytes/sec. 0 means unrestricted. You can append K or M(1K = 1024, 1M = 1024K). To limit the overall upload speed, use --max-overall-upload-limit option.

--seed-time=MINUTES Specify seeding time in (fractional) minutes. Also see the --seed-ratio option.

--seed-ratio=RATIO Specify share ratio. Seed completed torrents until share ratio reaches RATIO. You are strongly encouraged to specify equals or more than 1.0 here. Specify 0.0 if you intend to do seeding regardless of share ratio. If --seed-time option is specified along with this option, seeding ends when at least one of the conditions is satisfied.

--peer-id-prefix=PEER_ID_PREFIX Specify the prefix of peer ID. The peer ID in BitTorrent is 20 byte length. If more than 20 bytes are specified, only first 20 bytes are used. If less than 20 bytes are specified, random byte data are added to make its length 20 bytes.

--peer-agent=PEER_AGENT Set client reported during Extended torrent handshakes

--enable-dht[=true|false] Enable IPv4 DHT functionality. It also enables UDP tracker support. If a private flag is set in a torrent, aria2 doesn't use DHT for that download even if ``true`` is given.

--dht-listen-port=PORT... Set UDP listening port used by DHT(IPv4, IPv6) and UDP tracker. Multiple ports can be specified by using ',', for example: "6881,6885". You can also use '-' to specify a range: "6881-6999". ',' and '-' can be used together.

--dht-entry-point=HOST:PORT Set host and port as an entry point to IPv4 DHT network.

--dht-file-path=PATH Change the IPv4 DHT routing table file to PATH.

--bt-min-crypto-level=plain|arc4 Set minimum level of encryption method. If several encryption methods are provided by a peer, aria2 chooses the lowest one which satisfies the given level.

--bt-require-crypto[=true|false] If true is given, aria2 doesn't accept and establish connection with legacy BitTorrent handshake. Thus aria2 always uses Obfuscation handshake.

--bt-request-peer-speed-limit=SPEED If the whole download speed of every torrent is lower than SPEED, aria2 temporarily increases the number of peers to try for more download speed. Configuring this option with your preferred download speed can increase your download speed in some cases. You can append K or M(1K = 1024, 1M = 1024K).

--bt-max-open-files=NUM Specify maximum number of files to open in multi-file BitTorrent/Metalink downloads globally.

--bt-seed-unverified[=true|false] Seed previously downloaded files without verifying piece hashes.

--bt-max-peers=NUM Specify the maximum number of peers per torrent. 0 means unlimited. See also --bt-request-peer-speed-limit option.

-M, --metalink-file=METALINK_FILE The file path to the .meta4 and .metalink file. Reads input from stdin when '-' is specified.

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

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

--follow-metalink=true|false|mem If true or mem is specified, when a file whose suffix is .meta4 or .metalink, or content type of application/metalink4+xml or application/metalink+xml is downloaded, aria2 parses it as a metalink file and downloads files mentioned in it. If mem is specified, a metalink file is not written to the disk, but is just kept in memory. If false is specified, the .metalink file is downloaded to the disk, but is not parsed as a metalink file and its contents are not downloaded.

--metalink-enable-unique-protocol[=true|false] If true is given and several protocols are available for a mirror in a metalink file, aria2 uses one of them. Use --metalink-preferred-protocol option to specify the preference of protocol.

-h, --help[=TAG|KEYWORD] Print usage and exit. The help messages are classified with tags. A tag starts with "#". For example, type "--help=#http" to get the usage for the options tagged with "#http". If non-tag word is given, print the usage for the options whose name includes that word.

--no-conf[=true|false] Disable loading aria2.conf file.

--conf-path=PATH Change the configuration file path to PATH.

--stop=SEC Stop application after SEC seconds has passed. If 0 is given, this feature is disabled.

--header=HEADER Append HEADER to HTTP request header. You can use this option repeatedly to specify more than one header: aria2c --header="X-A: b78" --header="X-B: 9J1" http://host/file

-q, --quiet[=true|false] Make aria2 quiet(no console output).

--async-dns[=true|false] Enable asynchronous DNS.

--summary-interval=SEC Set interval to output download progress summary. Setting 0 suppresses the output.

--log-level=LEVEL Set log level to output to file specified using --log option.

--connect-timeout=SEC Set the connect timeout in seconds to establish connection to HTTP/FTP/proxy server. After the connection is established, this option makes no effect and --timeout option is used instead.
