In the process of learning Linux, if you want to master Linux, there are probably two situations. The first situation is the self-study mode. If you are self-taught, it will take about a year or even longer, depending on your own situation. But if you choose a professional training institution to study, it will be different. Under normal circumstances, basic training institutions can complete Linux operation and maintenance in May, and the learning content is more systematic, more suitable for enterprise needs, and there will be many actual projects.
