I don't follow what these are... this is what my text says... "When a process is started, a duplicate of that process is created. This new process is called the child and the process that created it is called the parent. The child process then replaces the copy for the code the parent process created with the code the child process is supposted to execute." The last sentance confuses me the most. Actually the entire thing confsues me. Why is a child process started anyways? Why does the parent process spawn a child process in the first place? And what's all this code copy stuff all about? The next paragraph states... "While the command is executing, the shell waits until the child process has completed. After is completes, the parent process terminates the child process, and a prompt is displated, ready for a new command" Why does this happen? I guess it goes back to my confusion about why the child process is created in the first place. __________________________________________________ Do You Yahoo!? Yahoo!
