Linux Command Line Tools (Full ver.)

If you study the main concepts of Linux, you can handle Linux more easily and more powerfully. I hope you build a solid foundation from the beginning!! :D

You know what Linux is and have learned some basic usage methods, but do you want to use the Linux shell better? Do you need to write Linux shell scripts? Well, it's time to learn Linux shell scripts!

This course combines topic-specific theory and programming practice to maximize learning effectiveness.

This is a concept-focused lecture for beginners who are new to Kubernetes. It explains step-by-step from the background of virtualization technology to Kubernetes components, structure, and operating principles. You can easily understand Kubernetes concepts and operating principles even without hands-on practice.

The ultimate goal of this course is to go beyond programming using IPC tools and to "develop the ability to appropriately select and design/implement IPC tools that fit software requirements."

When you join a company and start a project, you will start with setting up the server. At this time, you will not be able to set up properly without understanding the cloud and Linux. Learn the technologies and techniques for the cloud and Linux through this lecture!

This course is a course that helps you gain a basic understanding of Linux through hands-on practice and learn how to use commands using the terminal. I think that even students who have never encountered Linux before will find this course very helpful in gaining a basic understanding of Linux commands.

From the fundamentals of systems engineering to security setup, this course will guide you along the way.

This course puts an end to Linux server operational vulnerabilities caused by incorrect permissions. Master file and directory permission control based on real-world industry standards.

✅ Out of the entire series (1) ~ (7), (5) operating system, user interface, database ✅ CS101 series lectures - From basic computer theory to the latest practical examples - Provides a wide range of basic knowledge

The author of "Learning the Structure and Principles of the Linux Kernel through Debugging" properly explains the core interrupt concepts of the latest Linux kernel (v6.1), most used in system software.

We will create a remote development environment using VS Code and extensions, and learn about WSL and code-server, a VS Code used on the web.

Software development roles in the defense industry: ✔ Have different hiring criteria compared to general IT companies ✔ Use specialized tech stacks and development methodologies ✔ Offer very little information on how to effectively highlight your major, career, and projects. This course: 👉 Provides the perspective of a software developer who has experienced actual defense projects and hiring processes 👉 Explains how defense companies evaluate software developers 👉 Focuses on specific case studies to show you how to prepare your resume, interviews, and projects to increase your chances of success. This course transforms the state of "wanting to become a defense software developer but having no idea what to prepare" into a "clear roadmap you can start following right now."

The author of 'Linux Kernel Structure and Principles Learned Through Debugging' properly explains the core concept of the 'interrupt bottom half' in the latest Linux kernel (v6.1), most used in system software.

Creating an application on Linux (Ubuntu OS). (Cross-platform application development)

Let's experience collaborative application development in a Linux shell and open-source software environment, and set up the development environment required for coding!

This is a 'Practical Linux Troubleshooting Course' where you analyze and solve problems together with generative AI, based on a Docker practice environment that reproduces 5 representative failures that occur in actual Linux operating environments. Even those who were overwhelmed about where to start examining problems can learn the problem-solving approach and thought process of field engineers through AI guidance.

Now I can analyze the Linux kernel too! The easiest kernel lecture among Linux kernel lectures.

Learn systematically from the basic usage to the advanced features of Zabbix, an essential tool for effective monitoring of IT infrastructure. We offer the opportunity to grow into a monitoring expert using Zabbix through real-world application examples.

This course proceeds in stages, similar to the actual work, by learning and applying the necessary knowledge while configuring the infrastructure.
