Linux Basics by System Engineer: Bash Shell Script

If you are a beginner in Linux and want to get good at Linux,
Must-Know Basics Linux Bash Shell Script

Linux, the most widely used server operating system in the world!
This is a story about the basic CLI (Command Line Interface) commands , which are the first step to freely handling Linux, and shell scripts created by combining those commands.

This lecture will solve the questions and concerns that anyone interested in Linux would have had at first .

How to study Linux suggested by the instructor 📑

🤔This lecture started from a frequently asked question.

• ✅ For those who are learning Linux for the first time
  • 🤷🏻‍♀️Installing Linux was easy, but what do I do now?
  • 🤷🏻‍♂️There are so many commands and options, and I have no idea where to use them or when to use them.
• ✅ For those who are just starting to use Linux
  • 🤷🏻‍♀️I have a repetitive task that involves executing dozens of commands every day . Can't this be automated?
  • 🤷🏻‍♂️I know a few commands, but I'm not used to them all the time, so it's annoying to look them up.

For these people, rather than covering all the options and all the commands,
I will introduce commands and options that are frequently used when operating an actual system and show you in what situations they are used.

Linux Bash Shell Scripting Basics Goal ⛳

💁🏻💁🏻‍♂️Getting familiar with the commands and options that are essential when handling Linux.

It's enough to leave a vague memory of "I'm sure there was an order to do something like this..."
Because that alone allows you to find and issue commands to Linux.
And then I collected those commands and made them into a shell script.
It can automate repetitive tasks or make necessary repetitive tasks convenient and fast .

What happens when you take the Linux Bash Shell Scripting Basics course? 🎈

1. You will become familiar with commands that can be used in real-world work .
2. You will be able to handle a set of commands for investigating and reporting problems that occur when operating a system.
3. Complex tasks that are difficult to perform with commands alone can be performed cleanly and quickly through shell scripts .

What I'll teach you in this Linux Bash Shell Scripting Basics lecture! 🧐

• Linux and Shell
• Linux Commands
• Super simple shell script
• CLI editor
• Simple shell script
• Advanced Commands
• Basic lesson plan

Who should take the Linux Bash Shell Scripting Basics course? 🙋‍♀️

• Beginners or newbies who are not yet familiar with commands
• A dreamer who dreams of becoming a hacker
• A current developer who needs to learn Linux but has been putting off studying it
• A special person who wants to freely use the Linux operating system, which is different from what others use.
• People who dream of DevOps and SRE, which are popular these days
• Those who dream of becoming a System Engineer (SE) or System Administrator (SA)

Introducing Kang Min-gu, who will be giving a Linux lecture. 👏

Kang Min-gu , who started working as a server engineer in 2004, is currently an IT infrastructure engineer who is deeply familiar with Linux.
I created this course with the idea of creating a course that is a bit closer to practical use than the Linux courses available in Korea.

This Linux lecture consists of a basic part and a practical part . It consists of BASH commands and shell scripts that are essential for practical work, so please look forward to the practical part as well. :)

You can read more about the story in 🎙️👤Kang Min-gu's Xㅍㅍㅅㅅ article .

A Word from the Instructor for Linux Bash Shell Scripting 🙋‍♂️

Recently, there are many cases where Linux is installed as a server in the cloud to provide services.
A laptop that uses Linux as its desktop operating system (OS).
And although it is a slightly different series, many people use MacOS, which is similar to Linux.
There are more opportunities to use commands in a CLI (Command Line Interface) environment.

There are now more opportunities to come into contact with Linux in various cases than before.
People who are working or will work in this environment
The most basic thing you need to know is commands and options .
It is possible to automate various tasks by collecting them.
It's a shell script .

Linux is different from Windows
I vaguely thought it would be difficult because there was a lot of text.
If you look at them one by one, you will find that many of them are surprisingly simple.

I made this video so that you can approach it with a light heart and without any preconceptions .

The commands and options discussed here are provided in a form that can be used immediately in practice .

Of course, I am assuming various situations
When you want to check something in a certain situation
Because we're talking about using these commands and options, there are a variety of applications and uses that can be made of them.

Do you want to get better at Linux?
Do you dream of being a hacker?
Are you in a situation where you must use Linux?

I believe this will be a great first step towards taking the path you desire.
