Goals for this Hour

In this hour, you learn to use the many UNIX tools to help develop and debug your first program. Specifically, you learn about

• fget, a smarter FTP client

• Compiling the program with cc, the C compiler

• The invaluable make utility

• Additional useful C tools

First you learn how to do something sneaky with FTP to make it easier to use; then you learn how to put that into a simple C program. After that, you see the various UNIX tools at work helping develop the new software.

Just a warning: Some of the tools discussed herein aren't available in my favorite version of UNIX—Linux. I'll highlight them as you go along.
