Basic Usage

Downloading a Single File To download a single file, use the following command:

Replace with the actual link to the file you want to download. For example:
aria2c https://example.com/file.zip
Downloading Multiple Files You can also download multiple files simultaneously. Simply add the URLs separated by spaces:
aria2c https://example.com/file1.zip https://example.com/file2.zip
Using a Metalink File Aria2 supports Metalink files, which can provide multiple sources for a single file. To download from a Metalink file, use:
aria2c
Downloading via BitTorrent Aria2 can also handle BitTorrent downloads. To download a torrent file, use:
aria2c
Advanced Features
Aria2 offers several advanced features that enhance its functionality.
Download in Parallel Aria2 can split files into multiple segments and download them in parallel. This can significantly increase download speed. You can specify the number of connections using the -x option:
aria2c -x 16
This command will use 16 connections to download the file.
Resuming Interrupted Downloads If your download is interrupted, you can resume it using:
aria2c -c
The -c option tells aria2 to continue from where it left off.
Saving Downloaded Files By default, aria2 saves files in the current directory. You can specify a different directory using the -d option:
aria2c -d /path/to/directory
Using a Configuration File For users who frequently download files, creating a configuration file can save time. You can create a file named aria2.conf and specify options like:
dir=/path/to/directory
max-concurrent-downloads=5
You can then start aria2 with your configuration file:
aria2c –conf-path=/path/to/aria2.conf
