Linux Shell Script Master

With Linux Shell Script
Automate your servers and experience powerful features.

In the modern computing environment, Linux has long been an important mainstream operating system alongside Windows.

Linux is no longer the exclusive domain of hackers , and many developers are increasingly demanding Linux-based development . Future technologies like artificial intelligence, autonomous driving, machine learning, big data, cloud computing, and the Internet of Things are all being built on top of the Linux environment.

Many open source releases are first tested and supported on Linux.

🎨 The Linux shell is like a Swiss Army knife for developers.

For server-side JavaScript, Python, and other languages, the development environment is essentially a shell . Many engineers have found that direct access to simple command-line tools can be very efficient when working. For modern programming languages, dependency management and packaging can be handled from a shell-based perspective. The Linux shell

A shell provides users with a common environment and interface that anyone can access without installing complex components.

While the variety of programming languages and developer tools has increased, in many ways the operating platforms engineers use have become simpler.

🎨 Many enterprise customers have migrated from Unix to Linux platforms.

Engineers expect Docker to make the operating environment much more uniform and Linux-like.

Linux and shell skills are crucial for containerized workloads, which has led to increased interest in shells .
For open source , they are often built to run in containers on Linux.
The shell remains the most common way to administer Linux systems, and shell skills have become increasingly important as more developers standardize on Linux systems as their operating environment.

DevOps , a major trend in modern software development methods, has a single group responsible for both, rather than having one group focus on feature development and another on stable software operation.

🎨 Automation is closely tied to shell scripting.

Many tasks requiring automation can be easily handled using shell scripts . If you can't script it, you can't automate it, and automation is essential for operating increasingly complex systems.

ps. Shell scripts were used for filming , editing , and uploading this video . 🥳

However, the MacOS environment is a trap! :)

🎨 This lecture was created with the above purpose in mind.

Having worked with shell scripts for over 10 years, I know what's difficult and what's important .

There are two things you need to be good at shell scripting in Linux:

First , you need to be familiar with the shell syntax.
Special characters can have different functions depending on where they are used. For example, the redirection symbols < and > are also used in test statements.
Also, in the case of quotation marks, single quotation marks and double quotation marks must be used separately, and if you are not very careful when linking them with commands, it is easy to fail.

Second , you need to memorize about 20 to 30 essential Linux commands, including their options.
This is necessary because when you're quickly building a workflow using the pipe symbol, you'll need to immediately think of the appropriate command to use. You'll need to decide whether to use cut, tr, or brace expansion.

I took great care to make this video as easy to understand as possible even for Linux beginners.
To help you follow the class without difficulty, we explain basic terms using a rich subtitle system and animations.

🎨 This video features:

Feature 1. The video was created to look good on mobile smart devices .

Feature 2. We have taken care to avoid eye strain by using a black background and large font size .

Feature 3. Students can create their own scripts using the DRILL (practice problems) in the video.

Feature 4. Increased learning concentration by utilizing animation .
