I am a unix beginner, remember the first contact it was 3 years ago, when Hou that I was a student at the school, since after graduation will never come into contact with unix the system. Recently a friend gave me several books on unix, pick any one of them, just read dozens of pages, while combining the theoretical side of the operation, then had some small feelings, to share this with you, if do not agree with my views, welcome to give me valuable advice, not to agree not to agree with me, but in my communication with you. Here me say that I feel the benefits of several unix it!
First, you can use a simple design and methods to accomplish more complex and comprehensive works.
As we all know, unix basic idea is to dissect complex issues, using the simplest and most basic function modules stacked combination to solve complex problems. There are many benefits of doing so, the module features a single, easy to implement, easy stitching, design ideas clear, and the combination use, easy troubleshooting, easy management, so that the entire development flow more smoothly. Formal kind of thinking continues to this day, this led to standardized modular software design, software modules can repeat the theory and method, and further evolved into the present the important ideas of software engineering.
Second, support for multi-user multi-task.
Many people in the spare time or spare time want to study while listening to music while doing something, such as send e-mail again, or open a file and see, then, or open an instant messaging with friends, chat, etc. so, this is what we often say single-user multi-task scheduling strategy. unix is not only to support a user at a time and place on a variety of requests, but also to satisfy multiple users request the same and different. The following example of what I have come, such as a server, above a system administrator, web users, the conventional ordinary users so they will at the same time visit to this server, but the action is not the same, the system administrator may upload a file, web users may download an attachment, the conventional ordinary user may visit a page, then a server to respond to multiple actions at the same time, that multi-user multi-task. This feature of the show, gives users a great user experience, users will not find resources to be divided up, but their monopoly of the machine resources.
Third, the file system can easily loading and unloading.
Previously mentioned unix modular function, the system files so it can always be used "discarded." Users in the use of the process, according to their needs can be a hardware storage device at any time file system for loading and unloading. The system is to ensure that its simplicity. On the users, bringing great convenience.

Fourth, good openness and portability.
With the development of computing technology, people demand a variety of computer products will increase. Some programming enthusiasts, often according to their own need to write some programs running in the unix system to meet their needs. From another perspective, if a bad operating system adaptation, be applied in another system, may occur incompatible things, then that is terrible this time and effort to re-design project of the. In this way both the human and material resources to bring the waste. Therefore reflected in the good portability more compatibility on. I think this is many years in front of huge and ruthless market, there are still some who insist that a spirit of unix support it!
Fifth, a strong command functions.
In the absence of real contact with unix, I just heard that it has a very strong command function, when I really experienced it, really a kind of sense of Brief Encounter. A simple command to complete the necessary programming designed to achieve the function. A compound command to complete some of the operating system takes several or even dozens of commands to complete the action or function. Therefore, it gives users great convenience to many old customers word of mouth, the feeling they are really from the heart of love unix.
Sixth, improve the security mechanism.
unix security mechanism is recognized by all, no doubt. Including user management, protection of the system structure and the file permissions of the management. Many industry experts believe that: in comparison with other operating systems, unix-based platform used to build the information system and management mechanisms are also all relatively good and perfect. Today in our country and around the world in many key sectors to establish information management system is implemented using unix architecture.
Seventh, with network features.
Now the Internet has entered every household, leaving the network then we do not know how life goes on, the network in our lives plays a crucial role. In unix, it stressed that the internal communication mechanism and external devices more accessible, and to support the network environment is quite natural and smooth, and even has increased on the TCP / IP protocol support. With such a network support, would give those who are skeptical of unix network features users have been better explained. But I can not do without the network, but also started a kind of admiration for the unix.
I think they can not fully explain the advantages of unix, this is the beginning of my re-learning, then I will continue to research, to continue my journey unix. I will in future learning, slowly and shared with various unix experience, and we welcome you to join me explore demonstrate their!
