A download accelerator improves file transfer speeds by dividing a file into smaller parts and downloading them simultaneously. This method enhances the download process, especially in Linux environments, where terminal-based tools are preferred. Linux users can utilize command-line download accelerators to manage large files efficiently, particularly when working on remote servers or under limited bandwidth conditions.
One such tool for Linux is Axel, a command-line download accelerator that optimizes download speed by utilizing multiple connections. Unlike graphical download managers, Axel integrates seamlessly with the Linux terminal, making it ideal for users who prefer or require command-line operations. Axel is particularly useful for downloading large files or when network speed is a concern, providing a straightforward and efficient solution.
Using Axel in Linux allows users to bypass some speed restrictions imposed by servers and gain more control over their download processes. The simplicity of Axel makes it suitable for both novice and experienced users, offering a balance between ease of use and powerful functionality. This guide will cover the basic steps to install and use Axel to speed up your file downloads in Linux.
Steps to accelerate file downloads in Linux terminal:
- Open the terminal on your Linux system.
- Install Axel using your distribution's package manager.
$ sudo apt update && sudo apt install --assume-yes axel # Ubuntu and Debian
- Navigate to the directory where you want to save the downloaded file (optional).
$ cd Downloads/
- Copy the download URL from your browser (optional).
- Use Axel to download the file by pasting the URL into the terminal.
$ axel https://wordpress.org/latest.zip Initializing download: https://wordpress.org/latest.zip File size: 21.7178 Megabyte(s) (22772803 bytes) Opening output file wordpress-6.0.2.zip Starting download Connection 0 finished Connection 3 finished Connection 2 finished Connection 1 finished Connection 1 finished Connection 0 finished Connection 3 finished [100%] [..........................................] [ 3.8MB/s] [00:00] Downloaded 21.7178 Megabyte(s) in 5 second(s).
