cURL

    This subchapter looks at cURL, a UNIX (and Linux) command line tool.

    curl is used to interact with the internet. Linux also includes the similar wget command tool. You can download wget for free using fink.

    cURL is a command line tool and accompanying library for transferring data over the internet. cURL supports a wide variety of internet protocols, including DICT, FILE, FTP, FTPS, Gopher, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, POP3, POP3S, RTMP, RTSP, SCP, SFTP, SMTP, SMTPS, Telnet, and TFTP.

download a file

    You can use curl to download the content of a URL. The following command displays the HTML for Google as the STDOUT (on your Terminal screen):

    $ curl http://www.google.com

redirect a download

    You can redirect the results to file using the standard UNIX/Linux redirect. You will be given some status information if you redirect.

    $ curl http://www.google.com > google.html

    You can use the -o (lower case) to save the downloaded file with the name of your choice. You will see progress meter information as the download progresses. In the example, the download was so fast that only one status report was created.

    $ curl -o google.303 www.google.com

free music player coding example

    Coding example: I am making heavily documented and explained open source code for a method to play music for free — almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).

    View music player in action: www.musicinpublic.com/.

    Create your own copy from the original source code/ (presented for learning programming).
