What does the command 'wget' do?

The command 'wget' is specifically designed for downloading files from the web. It is a powerful utility that retrieves files using HTTP, HTTPS, and FTP protocols. This makes it particularly useful for users who want to obtain content from the internet, such as web pages, images, or software packages.

When you issue a 'wget' command, the tool connects to the specified URL, fetches the content, and saves it to your local filesystem. It provides several options for controlling the download process, including recursive downloads, support for proxy servers, and the ability to resume interrupted downloads.

The other options pertain to functions that 'wget' does not perform. For instance, compiling source code is typically handled by tools like 'make' or 'gcc.' Managing user permissions is a function associated with commands like 'chmod' or 'chown,' while backing up system data usually involves tools like 'tar' or 'rsync.' Therefore, 'wget' is unequivocally recognized for its capability to facilitate file downloads from the web.
