Linux internal strength
For those of you who want to build!

If you want to do something on Linux but don't know how, you can easily find the answer with an internet search. While this is a good way to quickly find and use it, it's not the best way to build your skills. To build your skills, you need to learn the many things surrounding it step by step.

Can you become a good carpenter simply by knowing how to saw and hammer? No. To become a good carpenter, you need a solid foundational knowledge of not only sawing and hammering, but also the properties of wood, the types and appropriate use of various tools, and design methods.

Shell (Linux shell, Linux shell) is the window through which you interact with Linux. And Bash is essentially the standard shell for Linux.
Ultimately, you need to be proficient in Bash to be able to use Linux well.

I wanted to create a course that would allow you to learn the various concepts, features, and usage of Bash in detail. I hope this course will provide you with a solid foundation in Bash knowledge and a solid understanding of each usage.
