This article will explain in detail the reasons why Linux operation and maintenance engineers must learn Shell programming. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Shell scripting language is an important tool for Linux / Unix system management and automatic operation and maintenance. The bottom layer of Linux / Unix system and the core of basic application software mostly involve shell script content.

Every qualified Linux system administrator or operation and maintenance engineer needs to be proficient in writing Shell scripting language and be able to read the contents of Shell scripts that come with the system and various software. Is it difficult to learn the shell scripting language by reducing unnecessary duplication of work and laying a good foundation for the efficient development of personal work? What are the Linux fundamentals needed to learn shell programming?

Shell is a command interpreter, and its function is to interpret and execute commands and programs entered by users. Each time a user enters a command, the shell program executes a command. After you enter a command from the keyboard, you can get an immediate response to the dialog box, which is called interactive mode.

Shell exists in the outer layer of the operating system. It is responsible for talking directly to the user, explaining the user's input to the operating system, processing the output results of various operating systems, and then inputting them into the client screen. When logging in to the Linux operating system, all operations are interpreted and performed by Shell. In short, shell is a command interpreter.
