GNU Wget
Wget is a free GNU command-line software that is used to download the data and files from the web servers (Internet). It is a part of the GNU Project. It uses the HTTP, HTTPS, and FTP protocols to download the contents and data. If the download fails due to certain problem, it resumes the file where it was left.
