Usage: aria2c [OPTIONS] [URI | MAGNET | TORRENT_FILE | METALINK_FILE]...

Printing options tagged with '#bittorrent'.

See 'aria2c -h#help' to know all available tags.

Options:

 --max-overall-download-limit=SPEED Set max overall download speed in bytes/sec.

                              0 means unrestricted.

                              You can append K or M(1K = 1024, 1M = 1024K).

                              To limit the download speed per download, use

                              --max-download-limit option.

                              Possible Values: 0-*

                              Default: 0

                              Tags: #http, #ftp, #bittorrent

 --max-download-limit=SPEED   Set max download speed per each download in

                              bytes/sec. 0 means unrestricted.

                              You can append K or M(1K = 1024, 1M = 1024K).

                              To limit the overall download speed, use

                              --max-overall-download-limit option.

                              Possible Values: 0-*

                              Default: 0

                              Tags: #http, #ftp, #bittorrent

 -V, --check-integrity[=true|false] Check file integrity by validating piece

                              hashes or a hash of entire file. This option has

                              effect only in BitTorrent, Metalink downloads

                              with checksums or HTTP(S)/FTP downloads with

                              --checksum option. If piece hashes are provided,

                              this option can detect damaged portions of a file

                              and re-download them. If a hash of entire file is

                              provided, hash check is only done when file has

                              been already download. This is determined by file

                              length. If hash check fails, file is

                              re-downloaded from scratch. If both piece hashes

                              and a hash of entire file are provided, only

                              piece hashes are used.

                              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

                              Possible Values: true, false

                              Default: false

                              Tags: #bittorrent

 --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).

                              Possible Values: 0-*

                              Default: 50K

                              Tags: #bittorrent

                              verifying piece hashes.

                              Possible Values: true, false

                              Default: false

                              Tags: #bittorrent

 --bt-hash-check-seed[=true|false] If true is given, after hash check using

                              --check-integrity option and file is complete,

                              continue to seed file. If you want to check file

                              and download it only when it is damaged or

                              incomplete, set this option to false.

                              This option has effect only on BitTorrent

                              download.

                              Possible Values: true, false

                              Tags: #bittorrent

 --bt-external-ip=IPADDRESS   Specify the external IP address to use in

                              BitTorrent download and DHT. It may be sent to

                              BitTorrent tracker. For DHT, this option should

                              be set to report that local node is downloading

                              a particular torrent. This is critical to use

                              DHT in a private network. Although this function

                              is named 'external', it can accept any kind of IP

                              addresses.

                              Possible Values: a numeric IP address

                              Tags: #bittorrent

 --bt-tracker-interval=SEC    Set the interval in seconds between tracker

                              requests. This completely overrides interval value

                              and aria2 just uses this value and ignores the

                              min interval and interval value in the response of

                              tracker. If 0 is set, aria2 determines interval

                              based on the response of tracker and the download

                              progress.

                              Possible Values: 0-*

                              Default: 0

 --bt-prioritize-piece=head[=SIZE],tail[=SIZE] Try to download first and last

                              pieces of each file first. This is useful for

                              previewing files. The argument can contain 2

                              keywords:head and tail. To include both keywords,

                              they must be separated by comma. These keywords

                              can take one parameter, SIZE. For example, if

                              head=SIZE is specified, pieces in the range of

                              first SIZE bytes of each file get higher priority.

                              tail=SIZE means the range of last SIZE bytes of

                              each file. SIZE can include K or M(1K = 1024, 1M =

                              1024K). If SIZE is omitted, SIZE=1M is used.

                              Possible Values: head[=SIZE], tail[=SIZE]

 --bt-tracker=URI[,...]       Comma separated list of additional BitTorrent

                              tracker's announce URI. These URIs are not

                              affected by --bt-exclude-tracker option because

                              they are added after URIs in --bt-exclude-tracker

                              option are removed.

                              download is completed in BitTorrent. To

                              select files, use --select-file option. If

                              it is not used, all files are assumed to be

                              selected. Please use this option with care

                              because it will actually remove files from

                              your disk.

                              Possible Values: true, false

                              Default: false

 --bt-detach-seed-only[=true|false]

                              Exclude seed only downloads when counting

                              concurrent active downloads (See -j option).

                              This means that if -j3 is given and this option

                              is turned on and 3 downloads are active and one

                              of those enters seed mode, then it is excluded

                              from active download count (thus it becomes 2),

                              and the next download waiting in queue gets

                              started. But be aware that seeding item is still

                              recognized as active download in RPC method.

                              Possible Values: true, false

                              Default: false

 --bt-force-encryption[=true|false]

                              Requires BitTorrent message payload encryption

                              with arc4. This is a shorthand of

                              --bt-require-crypto --bt-min-crypto-level=arc4.

                              If true is given, deny legacy BitTorrent

                              handshake and only use Obfuscation handshake and

                              always encrypt message payload.

                              Possible Values: true, false

                              Default: false

 --bt-enable-hook-after-hash-check[=true|false] Allow hook command invocation

                              after hash check (see -V option) in BitTorrent

                              download. By default, when hash check succeeds,

                              the command given by --on-bt-download-complete

                              is executed. To disable this action, give false

                              to this option.

                              Possible Values: true, false

                              Default: true
