Description
This course offers a complete introduction toShell Programmingin Linux/Unix environments, designed to help learners gain both theoretical understanding and practical skills in command-line scripting. Beginning with the installation of Ubuntu on VirtualBox, it introduces the Linux file system, directory structure, and a wide range of essential commands such as ls, pwd, cat, date, mkdir, rm, and chmod.

As the course progresses, learners explore text-processing utilities like grep, sort, and awk, along with powerful scripting features such as variables, command substitution, and user input handling. Detailed sessions on control statements (if, case, for, while, until, break, continue) enable learners to design structured and efficient shell programs. Advanced topics such as array variables and VIM editor usage help build proficiency in managing complex scripts and workflows.

Through hands-on demonstrations and examples, students will learn how to automate repetitive tasks, manage files, and streamline system operations effectively. By the end of the course, learners will have the ability to write, test, and debug shell scripts confidently — equipping them with essential skills for careers in Linux system administration, DevOps, and automation.

Key Words: Shell Programming: Linux Commands:  text-processing utilities manage files, and streamline system operations effectively: Linux system administration, DevOps, and automation.
