In today's society, linux is too widely used. There are countless Linux distributions now used on servers and embedded systems. Linux accounts for only 1% of desktop, but this does not mean that Linux is worse than Windows and Mac. In fact, these three desktop systems have their own merits. Now ubuntu, centos and other distributions are very convenient to use.

Before learning Linux, we should ask ourselves a few questions: Why do we need to learn Linux? What value can Linux bring us? How to learn Linux? What do we need to know? How long does it take? Before we learn, we must first find out the answers to these questions. We can't just follow the wind and see others learn. We will learn what others say. Only by understanding these problems can we learn without feeling bored and motivated.

Some students said that he wanted to learn Linux, asked me how to learn, I asked: Why learn, some said to see others learn, want to play; some said Linux employment is good, and so on. I would like to ask you what the purpose of learning Linux was, what the learning process was like, what level it is now, and what the process of learning Linux should be like.

So, below I will answer these puzzles for you one by one, hoping to help some students learn Linux as soon as possible.

Why should we learn Linux?

Linux can give you a job with a good salary, and it can also give you the opportunity to participate in the writing of open source software, learn from each other with programming experts, and programming is easier than windows.

What value can Linux bring us?

Linux can bring us a lot of emerging technologies, the value of technology is not how superb this technology is, but what value the technology itself brings to us, so many times we learn a technology, can not blindly learn, is to use this technology, know the use of this technology scenarios, know the convenience of this technology, we decided to study in depth.

How to learn Linux?

The first thing to learn about Linux is to choose a Linux distribution that can be installed on either a virtual machine or a physical machine. Then it was time to do more and give more orders. All books, no practice, everything is floating clouds.

1. First of all, the first thing to learn Linux is to learn Linux basics. In this regard, I recommend "Linux should be learned like this." The first few chapters explain the basic commands of Linux, pipe symbols, redirection, etc., understand this basic knowledge, and one command to practice, basically you will already be able to use Linux.

2. The second thing to learn about Linux is shell programming. Shell scripts are essential in operation and maintenance work. For complex and repetitive work, shell scripts can be written to help us better manage and maintain the server. Of course shell scripts can also make our other work easier. The book also has chapters devoted to shell programming. Personally, I think it's perfect for getting started. You can see more.

3. As mentioned earlier, Linux's greatest use is in the server domain, so the next thing you need to learn is to learn how to configure servers. The book also provides a lot of knowledge about server setup in the later chapters. Contains apache, ftp, dhcp, squid, samba and other servers to build and configure, write is also very detailed. Learn how to build and manage these servers, and then choose other servers according to personal interests and needs. Slowly, you will find that you use Linux and more and more comfortable, then you have mastered Linux.

What knowledge should we have?

To sum up learning Linux, the following knowledge points must be mastered:

1. Basic operating system configuration.

Basic network knowledge is really necessary, including network, hostname, etc. settings, which can usually be specified when installing the operating system.

2. Various common Linux commands.

Linux commands are very complex, but there are only a few commonly used ones, and the specific ones need to be slowly learned in use.

3. Linux operating system partition management, file management related commands.

One of the main functions of the operating system is to manage file systems, such as creating, opening, copying, deleting, moving, modifying files and other file operations.

4. Proficient in using an editor.

For example, VIM under the command line, gedit under the graphical interface and other editors.

5. Shell programming.

Shell is the scripting language in Linux, and for complex repetitive tasks, we can all use shell to help us.

7. Server installation and configuration

This part is a bit difficult and requires patience and perseverance, but by the time we learn this, we are basically familiar with Linux.

How long does it take?

The above is a Linux learning direction and route, for Linux learning is a process that needs to be adhered to, perhaps through self-study or training, 3 to 6 months can learn the basic knowledge, but focus on practice, in-depth thinking and continuous exploration, you will find more beauty of Linux! Finally recommend a search command site called linuxcool, I hope you can use it.
