Linuxシェルスクリプト

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

This is a course on Linux command line tools. We will carefully select frequently used tools and teach you about their core functions and frequently used options. And we will teach you how to use them in practice. If you use various Linux tools well, Linux will become easier. And you will understand and handle Linux better :)

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

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."

To those of you who are hesitating whether to learn Linux shell scripting or not, I will tell you one thing. Do you want to handle Linux in a cool way like a hacker? Can you imagine a hacker who doesn't know shell scripting? Then start right now!

If you have studied shell scripts, the next step is to learn how to effectively use the find, grep, sed, and awk commands. Don't search Google anymore to learn how to use these commands.
