The course covers in detail almost of the the C language, introduces the major tools and ideas of Unix programming, and shows how to use HTML forms to connect to remote databases and services. \fBWho is prepared for it?\fP .sp 6p We assume you know how to write computer programs. In particular, we assume you have written programs in a structured language, that you know about editors, understand the ideas of variables, loops, arrays, functions, and some data structures. If you have not written complicated programs that use these ideas in some language, you will be overtaxed by the course. \fBAdministative Details\fP .sp 6p .TS lI lw(5.25i).

Unix is an operating system, but it is more than just a control program for computers; it is a complete programming environment based on the idea of software tools. The Unix programming model is one of building complex, powerful solutions by combining simple, special-purpose tools. These tools are data manipulation programs. Every Unix system comes with a wealth of these tools. Tools are usually written in C. Combinations of tools are often written in a scripting language, such as the Unix shell, \fIsh\fP . Unix programming, then, consists of \fB(a)\fP designing and writing tools in C and \fB(b)\fP combining them using sh. Csci-e26 teaches C programming and sh programming. Where does CGI fit into this? To make your nifty combination of tools available from web pages, you need to learn how to connect web pages to Unix programs. The \fICommon Gateway Interface\fP is the method web pages use to transfer data from web page to a server and back. By learning this third skill, you will be able to construct Unix tools, combine them into Unix programs, and use web pages for user input and output. Each of these three skills is useful on its own. C is a great language; its syntax is the basis of C++, JavaScript, Perl, awk, Java. Unix is written in C as are most of the software tools. Shell scripting is an essential skill for Unix administration and for power users. CGI programming may be done in any language, not just C/Unix. The principles we cover apply to any network and programming platform.
