Which command is used to download files from the internet in Linux?

The command used to download files from the internet in Linux is wget. This utility is widely employed for retrieving files from the web using HTTP, HTTPS, and FTP protocols. It is particularly powerful due to its ability to handle recursive downloads, which allows users to download entire websites or directories while preserving the structure and hierarchy of the content.

Wget is designed for robustness, allowing downloads to resume if interrupted, and it can operate in the background, making it convenient for users who want to perform downloads without needing to keep a terminal open. This combination of features makes wget a popular choice for both simple file downloads and more complex web scraping tasks.

While curl is also a command-line tool for transferring data, it is generally more flexible for various protocols and is often used in scripting for interacting with web services. However, wget is specifically optimized for file downloads. The other options, such as fetch and getfile, do not exist widely in Linux environments or are not standardized commands for file downloading in the same way wget and curl are.
