curlyOr client-side URL request library, developed as a command-line application, can help you transfer files using URL syntax and save them on your computer.

The application supports multiple protocols, such as POP3, POP3S, DICT, FILE, FTP, HTTP, HTTPS, IMAP, FTPS, LDAPS, Gopher, Telnet, TFTP and SCP. In terms of certificates, it supports HTTP POST, HTTP PUT, SSL, HTTP form-based upload, user + password authentication, cookie, proxy, proxy tunnel, and file transfer recovery.

If all of this is not enough for you, you should know that cURL is an open source application, which means you are completely free to enhance its functionality or include it in third-party applications.

When you run cURL, it will display a progress meter informing you of the amount of data being transferred and the estimated completion time. This schedule can be viewed automatically on the terminal.

The application generates two independent projects: libcurl and curl. First, libcurl is an easy-to-use client-side URL transfer library, and curl uses URL syntax to receive and send files.

Libcurl can handle complete URL syntax with no length limit, and allows you to change the maximum acceptable download time and speed. Libcurl can also guess the protocol based on the host name, and provides standard proxy environment variable support.
