Chapter 19. Tips and Traps: Common Goofs for Novices

Nobody’s perfect. We all make mistakes, especially when we are first learning something new. We have all been there, done that. You know, the silly mistake that seems so obvious once you’ve had it explained, or the time you thought for sure that the system must be broken because you were doing it exactly right, only to find that you were off by one little character, one which made all the difference. Certain mistakes seem common, almost predictable, among beginners. We’ve all had to learn the hard way that scripts don’t run unless you set execute permissions on them—a real new-bie kind of error. Now that we’re experienced, we never make those mistakes anymore. What, never? Well, hardly ever. After all, nobody’s perfect.
