Some of the examples in this book are available electronically in a number of ways: by ftp, ftpmail, bitftp, and uucp. The cheapest, fastest, and easiest ways are listed first. If you read from the top down, the first one that works for you is probably the best. 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). Use BITFTP if you send electronic mail via BITNET. Use UUCP if none of the above works.
To use FTP, you need a machine with direct access to the Internet. A sample session is shown, with what you should type in boldface.

If the file is a compressed tar archive, extract the files from the archive by typing:
% zcat ksh.tar.Z | tar xf -
System V systems require the following tar command instead:
% zcat ksh.tar.Z | tar xof -
If zcat is not available on your system, use separate uncompress and tar commands.
