In the increasingly perfect GUI today, in the system management and other fields, shell programming still plays a role that can not be ignored. An in-depth understanding and proficiency in shell programming is one of the required lessons for every unix/linux user.

　　

When it comes to learning a new programming language, you might think of the so-called "10,000-hour law." In fact, to become a master, it is meaningless to know "10,000 hours" because the real key is not the training time, but the method of training.

　　

People's learning is divided into three districts: the comfort zone, the panic zone, the area before the two is called the learning area, also known as out of the comfort zone. So, the nature of learning is never comfortable, because you are doing things that you will not do. In the "comfort zone" work, call life, in the "Learning area" work, is called practice.
