Linux Shell Scripting Fundamentals (English)

You’ll discover that the shell is more than just a command interpreter, it is a complete programming language that lets you build your own tools and streamline workflows.







This course covers all the key building blocks of shell scripting: shebangs, variables, conditionals (if statements), loops (for, while), functions, and command substitution. You learn to work with input and output, environment variables, pipes, and redirection, and explore how to automate complex tasks using sed for batch editing and awk for data analysis and reporting. You also get to know different shells (bash, Bourne, Korn) and learn how to build small and larger programs within the shell. Step by step, you develop a strong foundation for creating your own scripts.







Learning happens fastest by doing, you’ll write and test your own scripts in a ready-to-use, browser-based lab environment. In addition to exploring loops, functions, and exit codes, you’ll practice extensively with sed and awk, quickly analyzing log files and text data. This hands-on approach shows how scripting can simplify and speed up everyday tasks while making your work more efficient and enjoyable.
