Chapter 24: Using the Web > The cURL Program

The cURL Program

The popularity of Lynx has spawned another similar product, called cURL. The cURL program allows you to automatically transfer files from the command line using a specified URL. It currently supports the FTP, FTPS, HTTP, HTTPS, SCP, SFTP, TFTP, telnet, DICT, LDAP, LDAPS, and FILE protocols as specified in URLs.

While cURL isn't used as a Web page browser per se, it allows you to easily send or retrieve data unattended directly from the command line, or your shell scripts, just by using a simple command. This provides a great tool to have in your shell scripting toolbox.

This section walks you through the process of installing and using cURL in your shell scripts.

Caution

There's also a programming language called curl, owned and marketed by the Sumisho Computer System Corporation. Don't confuse cURL with the curl programming language.
