What is the use of the 'wget' command?

The 'wget' command is a command-line utility widely used for downloading files from the web. Its primary function is to retrieve content from various sources such as HTTP, HTTPS, and FTP protocols. Users can specify a URL, and 'wget' will fetch the file located at that URL and save it to the local system. This command is particularly useful for downloading single files, entire websites, or resuming interrupted downloads. Its scripting capabilities also allow users to automate downloads, making it a powerful tool for both individual users and system administrators.

Other options refer to functionalities that are not associated with 'wget', such as uploading files, moving files, or connecting to databases, which are handled by different commands or applications in Linux.
