Exercises
First, go to the Web site http://www.intuitive.com/tyu24/ and download the files for this hour.
| 1: | What C development commands are available on your system? Use man -k to find out. |
| 2: | Use make to build the fget program. You might have to use the which command to find out exactly where your C compiler lives and then edit the Makefile to match. |
| 3: | Use fget to list the files available at ftp.intuitive.com. |
| 4: | Use lint to check the quality of the code, if available. |
Preview of the Next Hour
In the next hour, you learn about the Perl programming language and the many tools available on UNIX to help you develop software in this cool alternative to C.
