How to master the Linux system, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

What can linux do? I believe the vast majority of people have such doubts. Can I play PUBG? Can I play lol?

If you are evaluating the usability of linux in the name of entertainment, sorry, linux may not be suitable for you, because linux is a tool that teaches you to be smart, not to play. If you only think about entertainment, then windows may be more suitable for you.

So what's the difference between linux and windows?

If you ask me, the difference between linux and windows is like the difference between a digital camera and a SLR. A digital camera can easily take a picture and even has its own beauty function, but if you master how to use a SLR camera. The photos you take will be more delicate, more real and more beautiful. So this is why professional photographers take pictures with SLR cameras, while computer experts use linux systems. I am also a college student. Recommended by my teacher, I stepped into the road of learning linux. Of course, I also took a lot of detours during this period. In order to avoid fewer detours for linux lovers in the future, let's talk about my learning linux route.

The first step in learning linux is to learn the operation of the linux command. Why learn the command of linux in the first place? In fact, commands are equivalent to a piece of software. if you learn how to use commands, it is equivalent to learning to use software. what are the advantages of commands? I think there are two points: efficient: if you look at how many operations you have to execute a command, you can hardly feel the loss of time and can be done in an instant. For example, if you want to delete all the contents of a disk, use the command, just use the clean operation, instantly empty the disk, if you use the graphical interface operation, you click the empty disk operation, you may have to wait a long time to succeed, this is the charm of command operation. Flexibility: although these commands are simple, they can be combined to accomplish a lot of complex operations. If you use these commands flexibly, you will find that those graphical interface operations that cannot be completed can be done by borrowing commands.

If you want to learn these commands well, there is no other shortcut, but knock and practice more. In linux, commands can be divided into system basic commands and application commands. The basic system command is supported by all unix systems, and it remains the same wherever you go, as long as it is on a unix system. Such as ls,rm,rmdir,cp,cd and so on. There are about two hundred such simple and basic commands, which must be mastered. I once had an instruction reference manual, and the book is very good. This book is classified according to the commonly used index of commands, indicating that three stars are the most common commands, and must be mastered. Two stars are the best to remember, one star can be understood only a little, although they are all FC3 now But the classic UNIX basic commands have not changed after decades of changes! Some commands are rarely used, so they usually can't remember their use. for these commands, you should at least know that there is this command, have an impression in your mind, and check the manual when you need to use it, but you must never know the existence of this command! Practice one command at a time, so you can start to get started with linux.

The second step is that you can use it on the basis of mastering commands. The place where linux is most used is in the server field, so the second step you need to learn is to learn to build servers.

The third step, only simple operation of the linux system is not good, you also need to learn to program in linux's shell, what is shell? The shell tool in the Linux system is extremely useful. How does it work? When you learn shell carefully and thoroughly, we can write shell script files, and the automation of work can be realized with this script, which can reduce the repetitive work of many Linux systems, so that when deploying the server, it can effectively reduce the time and make the work efficient. After the implementation of these commands, shell can reduce the waste of server resources, maximize the available resources to the application software, provide production efficiency, achieve the optimal allocation of resources, and master shell script programming in the work is also very necessary!
