Description: This ius a topic that has been beaten to death both in books and on-line. For some reason, it seems that it is one of the most common misunderstandings that people have to face when learning how to write and/or configure their first cgi programs. This tutorial aims to clarify the concepts involved. Note that we will be referring to UNIX in a generic sense in this article. Most of what we are going to discuss here applies to all UNIX flavours. (such as Linux, SVR4, BSD etc.) It is also a good idea to type man chmod to check for the specific details on your system, too.
