About the Training

The Linux Shell Scripting Training is a hands-on program designed to equip participants with the skills to manage and automate a Linux system using shell scripts. This ability is essential for roles such as system administrators, data scientists, software developers, and other technology-focused positions. Linux shell scripting is commonly used in scenarios such as system automation, task automation, rapid prototyping, and data processing.

This training program teaches the fundamental principles of the Linux system shell, the basics of shell scripting language, and how to effectively use it. Participants will learn how to create shell scripts, use shell variables and arguments, control flow, loops, processes, shell debugging, and how to build programming structures for shell scripts.

The training also covers how to use shell tools and applications in various real-world scenarios such as system administration, data management, network management, and security. Additionally, participants will learn how to integrate and collaborate the Linux shell scripting language with other programming languages.

The skill of Linux shell scripting is applicable across various Linux distributions and Unix-based systems. Therefore, this training enables participants to develop the capability to use shell scripts on a wide range of systems. By the end of the training, participants will have a solid understanding and skill set to automate complex tasks using Linux shell scripting and perform various system and application management operations. These skills offer a significant advantage in any technology-focused position, helping participants to be more productive and effective in their work.

What Will You Learn?

In the Linux Shell Scripting Training, you will learn the following:
  • Basic concepts of shell programming languages
  • Commands and file structure used in shell scripts
  • Techniques for managing and processing data
  • Using functions and loops
  • Accessing system data
  • Automating processes
  • Debugging and reading error messages
