[aria2](https://aria2.github.io/) is a utility for downloading files. The supported protocols are [HTTP](../../internet/HTTP.md)(S), FTP, SFTP, [BitTorrent](../../tools/BitTorrent.md), and Metalink. aria2 can download a file from multiple sources/protocols and tries to utilize your maximum download bandwidth. It supports downloading a file from [HTTP](../../internet/HTTP.md)(S)/FTP/SFTP and [BitTorrent](../../tools/BitTorrent.md) at the same time, while the data downloaded from [HTTP](../../internet/HTTP.md)(S)/FTP/SFTP is uploaded to the [BitTorrent](../../tools/BitTorrent.md) swarm. Using Metalink's chunk checksums, aria2 automatically validates chunks of data while downloading a file like [BitTorrent](../../tools/BitTorrent.md). Aria2 can be used as a downloader by [yt-dlp](../media/yt-dlp.md).
|

|
||
## Usage
|
||
|
||
```shell
|
||
aria2c [<OPTIONS>] [<URI>|<MAGNET>|<TORRENT_FILE>|<METALINK_FILE>]
|
||
```
|
||
|
||
### Options
|
||
- The directory to store the downloaded file.
|
||
```shell
|
||
-d, --dir=<DIR>
|
||
```
|
||
|
||
- Downloads the URIs listed in **FILE**.
|
||
```shell
|
||
-i, --input-file=<FILE>
|
||
```
|
||
|
||
- Set the maximum number of parallel downloads for every queue item.
|
||
```shell
|
||
-j, --max-concurrent-downloads=<N>
|
||
```
|
||
|
||
- Check file integrity by validating piece hashes or a hash of entire file. This option has effect only in [BitTorrent](../../tools/BitTorrent.md), Metalink downloads with checksums or [HTTP](../../internet/HTTP.md)(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. Default: false
|
||
```shell
|
||
-V, --check-integrity [true|false]
|
||
```
|
||
|
||
- 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](../../internet/HTTP.md)(S)/FTP downloads.
|
||
```shell
|
||
-c, --continue [true|false]
|
||
```
|
||
|
||
- Set checksum. TYPE is hash type. The supported hash type is listed in Hash Algorithms in aria2c -v. DIGEST is hex digest. For example, setting sha-1 digest looks like this: sha-1=0192ba11326fe2298c8cb4de616f4d4140213838 This option applies only to [HTTP](../../internet/HTTP.md)(S)/FTP downloads.
|
||
```shell
|
||
--checksum=<TYPE>=<DIGEST>
|
||
```
|
||
|
||
- The maximum number of connections to one server for each download. Default: **1**
|
||
```shell
|
||
-x, --max-connection-per-server=<NUM>
|
||
```
|
||
|
||
- aria2 does not split less than 2*SIZE byte range. For example, let's consider downloading 20MiB file. If SIZE is 10M, aria2 can split file into 2 range (0-10MiB) and (10MiB-20MiB) and download it using 2 sources(if --split >= 2, of course). If SIZE is 15M, since 2*15M > 20MiB, aria2 does not split file and download it using 1 source. You can append K or M (1K = 1024, 1M = 1024K). Possible Values: 1M -1024M Default: 20M
|
||
```shell
|
||
-k, --min-split-size=<SIZE>
|
||
```
|
||
|
||
- The file name of the downloaded file. It is always relative to the directory given in --dir option.
|
||
```shell
|
||
-o, --out=<FILE>
|
||
```
|
||
|
||
- Download a file using N connections. If more than N URIs are given, first N URIs are used and remaining URIs are used for backup. If less than N URIs are given, those URIs are used more than once so that N connections total are made simultaneously. The number of connections to the same host is restricted by the --max-connection-per-server option. See also the --min-split-size option. Default: 5
|
||
```shell
|
||
-s, --split=<N>
|
||
```
|
||
|
||
- Verify the peer using certificates specified in --ca-certificate option. Default: true
|
||
```shell
|
||
--check-certificate [true|false]
|
||
```
|
||
|
||
- [HTTP](../../internet/HTTP.md) Auth
|
||
```shell
|
||
--http-user=<USER>
|
||
--http-passwd=<PASSWD>
|
||
```
|
||
|
||
- Load Cookies from FILE using the Firefox3 format (SQLite3), Chromium/Google Chrome (SQLite3) and the Mozilla/[Firefox](../network/browsers/Firefox.md)(1.x/2.x)/Netscape format.
|
||
```shell
|
||
--load-cookies=<FILE>
|
||
```
|
||
|
||
- Save Cookies to FILE in Mozilla/[Firefox](../network/browsers/Firefox.md)(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. Possible Values: /path/to/file
|
||
```shell
|
||
--save-cookies=<FILE>
|
||
``` |
