Linux is a free and open source Unix-like operating system, which was born on October 5, 1991 (the first official announcement). It was jointly developed by Finnish student Linus Torvalds and many enthusiasts who joined later. Compared with windows, open source is his unique feature, which makes it give you more permissions to achieve things that cannot be achieved on Windows. Of course, learning Linux plays an important role in entering the industry of IT.

How to learn Linux? For many people, it is another headache.

First, choose a more appropriate Linux distribution.

There are many Linux distributions, some for commercial use and some for individual users. Fedora is a community version based on RHEL,CentOS,Scientific Linux and Oracle Linux. There are significantly more packages packaged than RHEL,Fedora. One reason is that diverse communities are involved in building Fedora; it's not just a company. The relationship between SUSE, SUSE Linux Enterprise Server (SLES), and openSUSE is similar to that of Fedora, Red Hat Enterprise Linux, and CentOS. Debian is the upstream of many distributions, including Ubuntu, while Ubuntu is upstream of Linux Mint and other distributions. Debian is widely used in the field of server and desktop computer. Debian is a pure open source project and focuses on a key point of stability. It also provides the largest and complete software repository to users. Personally, I suggest you learn redhat, because Redhat is reliable and the kernel is relatively stable. I suggest you take a look at "that's how Linux should be learned", which is based on Redhat.

Second, learn some basic commands.

What is special about the Unix & Linux command line is that some options are designed to follow tradition, and you only need to know one to use similar functionality in other commands. Options are usually abbreviations of related functions, not meaningless English words. In addition to mastering some basic commands. Things like ls cd cat more mkdir rmdir vi rm tail. / or sh. The following parameters will also have to be seen.

Third, master some basic concepts of the operating system.

For a senior programmer, they can make good use of the interfaces left by the operating system to carry out in-depth programming, such as multithreaded programming, that is, using the resources of CPU to implement related programs, but as a more qualified programmer, you must master these. Such as inter-process communication, file operation, multithreaded programming, sock programming, etc., must be proficient in order to carry out the following operations, learn some big data, UI development and so on, however, you will find that after learning this, it is easier to learn new things by yourself.

Fourth, learn the code specification, distributed management code git service.

A qualified IT industry personnel, for their code, must be very organized, so not only neat, easier to maintain, to know that the code of a project, there are tens of thousands of lines, if not conditioning, then how to late maintenance and so on. Also, to learn code management, git is a good tool that allows you to implement code management quickly.
