Here's what you should know before you begin this course. You should have some information about the basic usage of the command line on your operating system. This course uses the unics command line under MacOS X. But many of the concepts provided are equally applicable to other command lines, including the MS-DOS command prompt. You should have some exposure to basic programming language concepts. If I say an if test or a FOR loop, I hope that this will not be a surprise to you. And you need to know how to use a text editor, any text editor in order to create and edit ASCII files.
I'm going to be using the VI editor in these examples, but any command line or GUI editor can be used, as long as it can create an edit ASCII files. That's all you need.
