What is Wget Command Line Tool
This article provides a quick overview of Wget, a widely-used command-line utility for downloading files from the internet. You will learn what Wget is, its key features, how it operates under the hood, and where to find its documentation to start using it effectively.
Understanding Wget
Wget (which stands for “World Wide Web get”) is a free, open-source software package used for retrieving files using widely used internet protocols: HTTP, HTTPS, and FTP. It is a non-interactive command-line tool, meaning it can run in the background while a user is not logged into the system. This makes it ideal for automated scripts, cron jobs, and large-scale data mirroring.
Key Features of Wget
- Non-Interactive Operation: Wget can perform downloads without user interaction, allowing you to start a process, log out, and let the system complete the task.
- Recursive Downloading: It can follow links in HTML pages to recreate the directory structure of a remote website, allowing you to download entire websites for offline viewing.
- Robustness: Wget is designed to handle unstable network connections. If a download is interrupted, it can resume from where it left off rather than starting over.
- Bandwidth Control: Users can limit download speeds to prevent Wget from consuming all available network bandwidth.

wget https://example.com/file.zipTo resume a partially downloaded file, use the -c
option:
