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 can download a file from
       multiple sources/protocols and tries to utilize your maximum download
       bandwidth. 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. The
           additional out and dir options can be specified after each line of
           URIs. This optional line must start with white space(s). See INPUT
           FILE section for details.

       -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 for every static
           (HTTP/FTP) URL, torrent and metalink. See also -s and -C option.
           Default: 5

       -V, --check-integrity[=true|false]
           Check file integrity by validating piece hashes. This option has
           effect only in BitTorrent 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 middle
           match and print the result. Available Values: basic, advanced,
           http, ftp, metalink, bittorrent, all Default: basic

   HTTP/FTP Options
       --all-proxy=PROXY
           Use this proxy server in the all protocols. You can override this
           setting and specify a proxy server for particular proctol using
           --http-proxy, --https-proxy and --ftp-proxy options. This affects
           all URLs. The format of PROXY is
           [http://][USER:PASSWORD@]HOST[:PORT]

       --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.
           Default: 60

       --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. You can append K or M(1K = 1024, 1M = 1024K). This option
           does not affect BitTorrent downloads. Default: 0

       --max-file-not-found=NUM
           If aria2 recieves `file not found' status from the remote HTTP/FTP
           servers NUM times without getting a single byte, then force the
           download to fail. Specify 0 to disable this option. This options is
           only effective only when using HTTP/FTP servers. Default: 0

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

       --no-proxy=DOMAINS
           Specify comma separated hostnames or domains to which proxy should
           not be used.

       -o, --out=FILE
           The file name of the downloaded file.

       Note
       In Metalink, BitTorrent download you cannot specify file name. The file
       name specified here is only used when the URLs fed to aria2 is done by
       command line without -i, -Z option. For example: aria2c -o myfile.zip
       http://mirror1/file.zip http://mirror2/file.zip

       --proxy-method=METHOD
           Set the method to use in proxy request.  METHOD is either get or
           tunnel. Default: tunnel

       -R, --remote-time[=true|false]
           Retrieve timestamp of the remote file from the remote HTTP/FTP
           server and if it is available, apply it to the local file. Default:
           false

       --retry-wait=SEC
           Set the seconds to wait to retry after an error has occured.
           Specify a value between 0 and 60. Default: 5

       --server-stat-of=FILE
           Specify the filename to which performance profile of the servers is
           saved. You can load saved data using --server-stat-if option. See
           SERVER PERFORMANCE PROFILE section below for file format.

       --server-stat-if=FILE
           Specify the filename to load performance profile of the servers.
           The loaded data will be used in some URI selector such as feedback.
           See also --uri-selector option. See SERVER PERFORMANCE PROFILE
           section below for file format.

       --server-stat-timeout=SEC
           Specifies timeout in seconds to invalidate performance profile of
           the servers since the last contact to them. Default: 86400
           (24hours)

       -s, --split=N
           Download a file using N connections. If more than N URLs are given,
           first N URLs are used and remaining URLs are used for backup. If
           less than N URLs are given, those URLs are used more than once so
           that N connections total are made simultaneously. N must be between
           1 and 16. Please see -j option too. Please note that in Metalink
           download, this option has no effect and use -C option instead.
           Default: 5

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

       --uri-selector=SELECTOR
           Specify URI selection algorithm. Possible values are inorder and
           feedback. If inorder is given, URI is tried in the order appeared
           in the URI list. If feedback is given, aria2 uses download speed
           observed in the previous downloads and choose fastest server in the
           URI list. This also effectively skips dead mirrors. The observed
           download speed is a part of performance profile of servers
           mentioned in --server-stat-of and --server-stat-if options.
           Default: inorder

   BitTorrent/Metalink Options
       --select-file=INDEX...
           Set file to download by specifing 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: 1-5,8,9.
           When used with the -M option, index may vary depending on the query
           (see --metalink-* options).

       Note
       In multi file torrent, the adjacent files specified by this option may
       also be downloaded. This is by design, not a bug. A single piece may
       include several files or part of files, and aria2 writes the piece to
       the appropriate files.

       -S, --show-files
           Print file listing of .torrent or .metalink file and exit. In case
           of .torrent file, additional information (infohash, piece length,
           etc) is also printed.

   BitTorrent Specific Options
       --bt-max-open-files=NUM
           Specify maximum number of files to open in each BitTorrent
           download. Default: 100

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

       --bt-require-crypto=true|false
           If true is given, aria2 doesn't accept and establish connection
           with legacy BitTorrent handshake(\19BitTorrent protocol). Thus
           aria2 always uses Obfuscation handshake. Default: false

       --bt-request-peer-speed-limit=SPEED
           In BitTorrent downloads, if the download speed is lower than SPEED,
           aria2 initiates and accepts connections ignoring max peer cap. You
           can append K or M(1K = 1024, 1M = 1024K). Default: 51200

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

           Set host and port as an entry point to DHT network.

       --dht-file-path=PATH
           Change the DHT routing table file to PATH. Default:
           $HOME/.aria2/dht.dat

       --dht-listen-port=PORT...
           Set UDP listening port for DHT. 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. Default:
           6881-6999

       --direct-file-mapping=true|false
           Directly read from and write to each file mentioned in .torrent
           file. Use this option if lots of files are listed in .torrent file
           and aria2 complains it cannot open files anymore. Default: true

       --enable-dht[=true|false]
           Enable DHT functionality. If a private flag is set in a torrent,
           aria2 doesn't use DHT for that download even if true is given.
           Default: false

       --enable-peer-exchange[=true|false]
           Enable Peer Exchange extension. If a private flag is set in a
           torrent, this feature is disabled for that download even if true is
           given. Default: true

       --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 action mentioned
           above is not taken. Default: true

       --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: 6881-6889,6999. Default: 6881-6999

       Note
       Make sure that the specified ports are open for incoming TCP traffic.

       -u, --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

       --peer-id-prefix=PEERI_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, the random alphabet
           characters are added to make it's length 20 bytes. Default: -aria2-

       --seed-ratio=RATIO
           Specify share ratio. Seed completed torrents until share ratio
           reaches] RATIO. I strongly encourages you 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. Default: 1.0

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

       -T, --torrent-file=TORRENT_FILE
           The path to the .torrent file. You may not use this option because
           you can specify torrent file without -T.

   Metalink Specific Options
       --follow-metalink=true|false|mem
           If true or mem is specified, when a file whose suffix is ".metaink"
           or content type is "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 action
           mentioned above is not taken. Default: true

       -M, --metalink-file=METALINK_FILE
           The file path to .metalink file. You may not use this option
           because you can specify metalink file without -M.

       -C, --metalink-servers=NUM_SERVERS
           The number of servers to connect to simultaneously. Some Metalinks
           regulates the number of servers to connect. aria2 strictly respects
           them. This means that if Metalink defines the maxconnections
           attribute lower than NUM_SERVERS, then aria2 uses the value of
           maxconnections attribute instead of NUM_SERVERS. See also -s and -j
           options. Default: 5

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

       --metalink-location=LOCATION[,...]
           The location of the preferred server. A comma-deliminated list of
           locations is acceptable, for example, JP,US.

       --metalink-os=OS
           The operating system of the file to download.

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

       --metalink-preferred-protocol=PROTO
           Specify preferred protocol. The possible values are http, https,
           ftp and none. Specifiy none to disable this feature. Default: none

       --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. Default: true

   Advanced Options
       --allow-overwrite=true|false
           If false is given, aria2 doesn't download a file which already
           exists but the corresponding .aria2 file doesn't exist. In
           HTTP(S)/FTP download, if --auto-file-renaming=true then, file name
           will be renamed. See --auto-file-renaming for details. Default:
           false

       --allow-piece-length-change=true|false
           If false is given, aria2 aborts download when a piece length is
           different from one in a control file. If true is given, you can
           proceed but some download progress will be lost. Default: false

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

       --auto-file-renaming[=true|false]
           Rename file name if the same file already exists. This option works
           only in HTTP(S)/FTP download. The new file name has a dot and a
           number(1..9999) appended. Default: true

       --auto-save-interval=SEC
           Save a control file(*.aria2) every SEC seconds. If 0 is given, a
           control file is not saved during download. aria2 saves a control
           file when it stops regardless of the value. The possible values are
           between 0 to 600. Default: 60

       --conf-path=PATH
           Change the configuration file path to PATH. Default:
           $HOME/.aria2/aria2.conf

       -D, --daemon
           Run as daemon.

       --enable-direct-io[=true|false]
           Enable directI/O, which lowers cpu usage while allocating/checking
           files. Turn off if you encounter any error. Default: true

       --file-allocation=METHOD
           Specify file allocation method. METHOD is either none or prealloc.
           none doesn't pre-allocate file space.  prealloc pre-allocates file
           space before download begins. This may take some time depending on
           the size of the file. Default: prealloc

       --log-level=LEVEL
           Set log level to output. LEVEL is either debug, info, notice, warn
           or error. Default: debug

       --summary-interval=SEC
           Set interval in seconds to output download progress summary.
           Setting 0 suppresses the output. Default: 60

       Note
       In multi file torrent, the files adjacent forward to the specified
       files are also allocated if they share a same piece.

       -Z, --force-sequential[=true|false]
           Fetch URIs in the command-line sequentially and download each URI
           in a separate session, like the usual command-line download
           utilities. Default: false

       --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

       --no-conf
           Disable loading aria2.conf file.

       --no-file-allocation-limit=SIZE
           No file allocation is made for files whose size is smaller than
           SIZE. You can append K or M(1K = 1024, 1M = 1024K). Default: 5M

       -P, --parameterized-uri[=true|false]
           Enable parameterized URI support. You can specify set of parts:
           http://{sv1,sv2,sv3}/foo.iso. Also you can specify numeric
           sequences with step counter: http://host/image[000-100:2].img. A
           step counter can be omitted. If all URIs do not point to the same
           file, such as the second example above, -Z option is required.
           Default: false

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

       --realtime-chunk-checksum=true|false
           Validate chunk of data by calculating checkusm while download a
           file if chunk checksums are provided. Currently Metalink is the
           only way to to provide chunk checksums. Default: true

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

       -v, --version
           Print the version number, copyright and the configuration
           information and exit.

   OPTIONS THAT TAKE AN OPTIONAL ARGUMENT
       The options that have its argument surrounded by square brackets([])
       take an optional argument. Usually ommiting the argument is evaluated
       to true. If you use short form of these options(such as -V) and give an
       arugment, then the option name and its argument should be
       concatenated(e.g. -Vfalse). If any spaces are inserted between the
       option name and the argument, the argument will be treated as URI and
       usually this is not what you expect.


   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.



EXAMPLES

   HTTP/FTP Segmented Download
       Download a file
                  aria2c http://host/file.zip

              Note
              aria2 uses 5 connections to download 1 file by default.


       Download a file using 1 connection
                  aria2c -s1 http://host/file.zip

              Note
              aria2 uses 5 connections to download 1 file by default. -s1
              limtis the number of connections to just 1.


              Note
              To pause a download, press Ctrl-C. You can resume the transfer
              by running aria2c with the same argument at the same directory.
              You can change URLs as long as they are pointing to the same
              file.


       Download a file from 2 different HTTP servers
                  aria2c http://host/file.zip http://mirror/file.zip

       Download a file from HTTP and FTP servers
                  aria2c http://host1/file.zip ftp://host2/file.zip

       Download files listed in a file concurrently
                  aria2c -ifiles.txt -j2

              Note
              -j option specifies the number of parallel downloads.


       Using proxy
              For HTTP:


                  aria2c --http-proxy=http://proxy:8080 http://host/file
              For FTP:


                  aria2c --ftp-proxy=http://proxy:8080 ftp://host/file

              Note
              See --http-proxy, --https-proxy, --ftp-proxy and --all-proxy for
              details. You can specify proxy in the environment variables. See
              ENVIRONMENT section.

                  aria2c -p --lowest-speed-limit=4000 file.metalink

              Note
              To pause a download, press Ctrl-C. You can resume the transfer
              by running aria2c with the same argument at the same directory.


       Download several local metalink files
                  aria2c -j2 file1.metalink file2.metalink

       Download only selected files using index
                  aria2c --select-file=1-4,8 file.metalink

              Note
              The index is printed to the console using -S option.


       Download a file using a local .metalink file with user preference
                  aria2c --metalink-location=JP,US --metalink-version=1.1 --metalink-language=en-US file.metalink

              --max-upload-limit specifies the max of upload rate.


              Note
              To pause a download, press Ctrl-C. You can resume the transfer
              by run aria2c with the same argument at the same directory.


       Download 2 torrents
                  aria2c -j2 file1.torrent file2.torrent

       Download a file using torrent and HTTP/FTP server
                  aria2c -Ttest.torrent http://host1/file ftp://host2/file

              Note
              Downloading multi file torrent with HTTP/FTP is not supported.


       Download only selected files using index(usually called "selectable
       download")
                  aria2c --select-file=1-4,8 file.torrent

              Note
              The index is printed to the console using -S option.


       Change the listening port for incoming peer
                  aria2c --listen-port=7000-7001,8000 file.torrent

              Note
              Since aria2 doesn't configure firewall or router for port
              forwarding, it's up to you to do it manually.


       Specify the condition to stop program after torrent download finished
                  aria2c --seed-time=120 --seed-ratio=1.0 file.torrent

              Note
              In the above example, the program exists when the 120 minutes
              has elapsed since download completed or seed ratio reaches 1.0.


       Throttle upload speed
                  aria2c --max-upload-limit=100K file.torrent

       Enable DHT
                  aria2c --enable-dht --dht-listen-port=6881 file.torrent

              Note
              DHT uses udp port. Since aria2 doesn't configure firewall or
              router for port forwarding, it's up to you to do it manually.


   More advanced HTTP features
       Load cookies
                  aria2c --load-cookies=cookies.txt http://host/file.zip

              Note
              You can use Firefox/Mozilla's cookie file without modification.


       Resume download started by web browsers or another programs
                  aria2c -c -s2 http://host/partiallydownloadedfile.zip

       Client certificate authorization for SSL/TLS
                  aria2c --certificate=/path/to/mycert.pem --private-key=/path/to/mykey.pem https://host/file

              Note
              The file specified in --private-key must be decrypted. The
              behavior when encrypted one is given is undefined.


       Verify peer in SSL/TLS using given CA certificates
                  aria2c --ca-certificate=/path/to/ca-certificates.crt --check-certificate https://host/file

   And more advanced features
       Throttle download speed
                  aria2c --max-download-limit=100K file.metalink

       Repair a damaged download using -V option
                  aria2c -V file.metalink

              Note
              This option is only available used with BitTorrent or metalink
              with chunk checksums.


       Drop connection if download speed is lower than specified value
                  aria2c --lowest-speed-limit=10K file.metalink

       Parameterized URI support
              You can specify set of parts:


                  aria2c -P http://{host1,host2,host3}/file.iso
              You can specify numeric sequence:


                  aria2c -Z -P http://host/image[000-100].png

              Note
              -Z option is required if the all URIs don't point to the same
              file, such as the above example.


              You can specify step counter:


                  aria2c -Z -P http://host/image[A-Z:2].png

       Parallel downloads of arbitrary number of URL,metalink,torrent
                  aria2c -j3 -Z http://host/file1 file2.torrent file3.metalink

       BitTorrent Encryption
              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 -V option to
       aria2c in command-line.



SEEDING DOWNLOADED FILE IN BITTORRENT

       You can seed downloaded file using -V option.


           aria2c -V file.torrent


INPUT FILE

       The input file can contain list of URIs to feed them into aria2. You
       can specify multiple URIs for a single entity: separate URIs on a
       single line using the TAB character.

       Each line is treated as if it is provided in command-line argument.
       Therefore they are affected by -Z and -P options. The additional out
       and dir options can be specified after each line of URIs. This optional
       line must start with white space(s).

       For example, let the content of uri.txt be


           http://server/file.iso http://mirror/file.iso
             dir=/iso_images
             out=file.img
           http://foo/bar
       If aria2 is executed with -i uri.txt -d /tmp options, then file.iso is
       saved as /iso_images/file.img and it is downloaded from
       http://server/file.iso and http://mirror/file.iso. The file bar is
       downloaded from http://foo/bar and saved as /tmp/bar.

       In some cases, out parameter has no effect. See note of --out option
       for the restrictions.



SERVER PERFORMANCE PROFILE

       This section describes the format of server performance profile. The
       file is plain text and each line has several NAME=VALUE pair, delimited
       by comma. Currently following NAMEs are recognized:

       host
           Hostname of the server. Required.

       protocol
           Protocol for this profile, such as ftp, http. Required.

       dl_speed
           The average download speed observed in the previous download in
           bytes per sec. Required.

       last_updated
           Last contact time in GMT with this server, specified in the seconds
           from the Epoch. Required.

       status
           ERROR is set when server cannot be reached or out-of-service or
           timeout occurred. Otherwise, OK is set.
       Those fields must exist in one line. The order of the fields is not
       significant.You can put pairs other than above; they are simply
       ignored.

       An example is follow:


           host=localhost, protocol=http, dl_speed=32000, last_updated=1222491640, status=OK
           host=localhost, protocol=ftp, dl_speed=0, last_updated=1222491632, status=ERROR


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
       By default, the routing table of DHT is saved to the path
       $HOME/.aria2/dht.dat.
