[Preface] Exercises

Exercises

The exercises in this book are available electronically by FTP and FTPMAIL. Use FTP if you are directly on the Internet. Use FTPMAIL if you are not on the Internet but can send and receive electronic mail to Internet sites. (This includes CompuServe users.)

FTP

If you have an Internet connection (permanent or dialup), the easiest way to use FTP is via your web browser or favorite FTP client. To get the examples, simply point your browser to:

ftp://ftp.oreilly.com/published/oreilly/nutshell/learning_perlnt/examples.zip

If you don't have a web browser, you can use the command-line FTP client included with Windows NT (or Windows 95).

FTPMAIL

FTPMAIL is a mail server available to anyone who can send electronic mail to, and receive electronic mail from, Internet sites. Any company or service provider that allows email connections to the Internet can access FTPMAIL.

You send mail to ftpmail@online.oreilly.com. In the message body, give the FTP commands you want to run. The server will run anonymous FTP for you, and mail the files back to you. To get a complete help file, send a message with no subject and the single word "help" in the body. The following is an example mail message that gets the examples. This command sends you a listing of the files in the selected directory and the requested example files. The listing is useful if you are interested in a later version of the examples.

Subject: 
reply-to username@hostname      (Message Body) Where you want files mailed 
open 
cd /published/oreilly/nutshell/learning_perlnt
dir 
get README 
mode binary
uuencode
get examples.zip
quit
.

A signature at the end of the message is acceptable as long as it appears after "quit."
