Wget Command

Wget Command in Linux: Wget is a command-line utility of Linux that lets you download files from the web. It is a non-interactive downloader, meant that it can work well in the background without obstructing the current process. The Wget command supports protocols like HTTP, HTTPS, and FTP, as well as retrieval by means of HTTP proxies. Users don’t have to log on to the system for using the wget command. Many web browsers require continual user presence while transferring a lot of download data. But, this command has been designed for robustness over an unstable or slow internet connection. So, if your download interrupts or fails due to a network problem, it will keep on trying to download the file until the download gets completed. It will command the server to resume the download where it left off so you don’t have to worry about any sort of network error. In this article, we will help you with how to use wget command in Linux Ubuntu.
