If you really need to learn Linux urgently for practical use, I reeeeally recommend this course. The instructor kindly teaches the essential Linux basics that you absolutely must know. Therefore, Linux beginners should definitely take this course as a must. After watching this course, I would be grateful if the instructor could open other Linux-related courses like this one. This course isn't just recommended - it's a must-take course for anyone entering the IT industry. It's a really great course.

If you're a Linux beginner, you must take this course. I encountered Linux for the first time in my life at a bootcamp and have been taking Linux classes there, but because bootcamps naturally move through material very quickly, my mental state was completely shattered. However, after taking this course, I'm starting to gradually understand the content from classes and books, and I'm slowly gaining confidence. While it doesn't cover all Linux content, this course is giving me the ability to study on my own!!!

I was worried because I'm not from a computer science background, but the course structure of introducing Linux, learning commands used in real-world scenarios, and internalizing them through practice and hands-on experience is excellent! If you're new to Linux or worried because you're not from a CS background, I highly recommend Instructor Park Jae-seong's course!!

What you will gain after the course

  • Those who are learning Linux for the first time

  • Anyone who has struggled with a "Permission denied" error before

  • Anyone who has struggled with the "port already in use" error?

  • Those who want to quickly learn Linux commands frequently used in real-world practice.

  • Those who want to learn Linux commands frequently used when operating actual backend servers.


🤬 Linux commands keep holding me back...

My name is Jaeseong Park, and I started my career in development as a non-major, served as a CTO at several companies, and am currently active as an educator.

When I was a student, I taught myself development to become a backend developer. However, the more I learned about backend concepts, the more Linux commands held me back. I had to enter Linux commands to run backend servers, and I had to use Linux commands even when installing various programs.

At first, I barely managed to keep up by copying and pasting Linux commands that people had written on their blogs just to get things working somehow. However, I was just blindly typing along without even knowing what the Linux commands I was entering actually meant.

Because I was studying this way, when an error occurred after entering a command, it was difficult to analyze the cause or find a solution. That's why I made up my mind to start studying Linux in earnest.

However, when I actually tried to learn Linux, I bought a thick book. But since this book contained every single concept related to Linux, it felt overwhelming to study it all, and I had no idea how to apply what I learned in practice. Looking back now, I feel like I spent a lot of time studying commands that are rarely used in the real world.

That is why I created this course so that those learning Linux for the first time can learn it efficiently and practically. The fastest way to learn something is to focus on the most frequently used and essential content and apply it directly in practice. That is how you become familiar with it quickly and learn effectively.

The goal of this course is to quickly master the Linux commands frequently used in developing, deploying, and operating actual services, so that you can apply them immediately in the field. I hope you don't study Linux inefficiently as I did, but instead use this course to learn only the essential Linux commands that are frequently used in practice.

I'll see you in the course!😊

👍 This course is perfect for people like this!

Those who are having difficulty learning
Linux by watching YouTube or reading blogs

Those who are non-majors and
slow to understand difficult
concepts and terminology

Those who find their progress in studying development
held back by
Linux commands

🙊 What will you achieve after completing this course?

You will be able to master essential Linux concepts and commands frequently used in practice. Furthermore, you will learn in which real-world situations the Linux commands you've learned are applied..

Notes

If you encounter any parts you don't understand while studying, please ask right away using the Q&A board or the 1:1 open chat room😊

🚨 Be sure to check what kind of person the educator is!

If you meet the wrong doctor, you may face death because your illness cannot be cured at that moment. However, death ends with the pain of that moment. But if you meet the wrong teacher and receive the wrong education, you will suffer throughout your entire life.

Due to poor education, you may end up at a company you don't want, receive a lower salary than expected, and suffer for the rest of your life as a result. Not only that, but the poor education you received can even be passed down to your children.

I believe that education can truly change a person's life for the better, but on the other hand, it can also completely ruin a person's life. That is why I believe education carries such a heavy responsibility.

Therefore, please check who the educator is, what kind of person they are, and what path they have taken, and make a careful judgment.

👋 Hello!
I'm finally introducing myself ( ⸝⸝•ᴗ•⸝⸝ )੭⁾⁾

Hello!

I started studying development as a non-major. Somehow, I've already become a developer in my 6th year! Recently, I served as CTO at two companies while working as a developer. Whenever I had spare time, I've been doing coding lectures, corporate development consulting, and speaking engagements.. Bất cứ khi nào có thời gian rảnh, tôi đều thực hiện các bài giảng về lập trình, tư vấn phát triển cho công ty và diễn thuyết.

The number of students I have taught has already exceeded 24,000 (as of July '25)! As I feel every time I teach my students, I can never forget the sense of fulfillment that comes from education, so I plan to continue providing courses on Inflearn.
(* Produced successful candidates for Kakao Pay, Yanolja, and Woowa Bros among students)

Just as I received a lot of help when I was going through difficult and challenging times, I wanted to become someone who could also help many others. I felt the most proud and happy when the value I created through development had a positive impact on other people.

For these reasons, I hope that by giving back and sharing what I have worked hard to achieve, those people can live a slightly better life.

Thank you!
