This article provides a concise guide on how to display the full list of command-line arguments for the aria2c utility within the Ubuntu operating system. Understanding these parameters is crucial for configuring downloads, managing connections, and optimizing performance using this lightweight tool. The following sections detail the specific terminal commands required to access this documentation instantly.

To list all available options for aria2c in the terminal, you need to use the help flag. Open your terminal window and execute the following command:

aria2c -h

Alternatively, you can use the long-form version of the same command:

aria2c --help

Running either of these commands will print a comprehensive list of supported options, switches, and configurations directly to your standard output.

aria2c -h | less

Use the spacebar to scroll down and press q to exit the view when you are finished. For more detailed information including examples and configuration file syntax, you can also access the manual page by typing man aria2c.
