cURL transfers data to or from a server using the HTTP, HTTPS, or FTP protocols. It supports POST, cookies, authentication, downloading partial files from a specified offset, referer, user agent string, extra headers, limiting speed, maximum file size, progress bar, and more. cURL is useful for maintaining a website, retrieving data, and checking server configurations.
A primer on cURL
Getting ready
Unlike wget, cURL is not included in all Linux distros; you may have to install it with your package manager.
By default, cURL dumps downloaded files to stdout, and progress information to stderr. To disable displaying progress information, use the --silent option.
