Wget

Wget is a free, non-interactive console program for downloading files over the network. It supports the HTTP, FTP, and HTTPS protocols, and also supports operation through an HTTP proxy server.

Wget is a non-interactive program. That means that when it is launched, the user can only change how it works using the operating system's own process controls. Usually the Ctrl+C key combination is used to interrupt the program, and Ctrl+Z to put the current job in the background. Modern web browsers usually have a function of downloading files, but since the browser is designed for interactive mode, downloading a large number of files manually can be tedious. Browsers do not usually provide tools to automate such tasks. Wget, for example, supports downloading URLs specified in a file. In this way, one can make a list of the files and then use wget to download them at a convenient time. The wget command line interface makes it possible to manage wget from other programs and scripts, and this is useful for automating downloads (regular updates, monitoring the availability of the server, etc.).

Wget can download any files on the World Wide Web (including (X)HTML pages) via http and https, as well as files and directories via ftp.

Files can be downloaded recursively through links in html pages, either from one site with a certain link depth, or from several sites. In addition, when downloading via ftp, files can be downloaded "by name mask" (that is, you can specify a group of files using "*").

Wget supports file retrieval in case of a broken connection.
