For programmers, do they have to master the Linux operating system?
Recall the Google search, Taobao shopping, and QQ and WeChat chats you use. In fact, behind these software and services are thousands of Linux servers supporting them.
For software engineers, you will almost certainly encounter the application scenarios of Linux. If you can’t operate Linux proficiently, it basically means half your skills and half your chances.
But the biggest difficulty in learning Linux is that its instructions involve all aspects, and each command has a lot of related parameters. It is no clue to learn, and the information on the network is also uneven. If you encounter problems, you don't know where to start.
After mastering the basic knowledge, I am at a loss for Linux performance optimization. How to find tools based on indicators? Or find indicators based on tools? How to quickly locate performance problems? What are the logic and steps for performance analysis?
Or I still want to learn operating system principles in depth, but I can't remember the core process, and I don't know if there is a clear and concise schematic diagram to assist my understanding.
Today I recommend a " big object ", 1.56 meters (approximately the length of the arms spread) Linux operating system knowledge map , produced by the GeekTime team, which can be described as the hardest IT skills map in 2019. The above questions can help you solve.
As long as your job is related to the operating system, this knowledge map will definitely become an indispensable assist in your interview and work.
