Linux Course for Beginners: A Comprehensive Course Guide

Who is this Linux Course for?

Developers who haven’t used Linux OS before
Linux OS beginners who want to master basic Linux commands
Anyone who wants to understand Linux OS basic mechanism comprehensively

Introduction to Linux Course

Linux is the most important OS (Operating System) for servers. 96.3 percent of the top 1 million web servers are running Linux according to ZDNet. Recently, web servers have been running on the public cloud. When you host your website on the public cloud, you may still use a Linux OS virtual machine (instance) on AWS, GCP, Azure, or other public cloud infrastructure.

Learning the basics of Linux OS is very useful for all types of engineers. After going through this course, you'll be able to operate Linux OS through the command line.This course also shows actual operation examples using AWS Lightsail, which can quickly provide access to the Linux OS environment.

Throughout this course, you will learn:

Key functionalities of Linux OS
Basic Linux commands
Remote server operation
User and user group management (permission setting)
Process management with Linux OS

What you will achieve in this Linux course

Expected Achievement 1

Master Linux Commands

You'll master ~40 key Linux commands. You can practice them in the actual Linux environment using AWS.

Expected Achievement 2

Manage Servers Remotely

You'll be able to operate a remote Linux server connected through SSH. You’ll also master how to use VS Code for remote Linux server operations.

Managing Remote Servers with VS Code Through SSH

Expected Achievement 3

Create Auto Running Programs

You'll build an auto-running program using a shell script through simply copying and pasting our guided code.

Creating Auto-Running Program By Code Snippet Copy and Paste

Expected Achievement 4

Master Vim Operation

You'll be able to master Vim text editor operations with our visual guide.

Expected Achievement 5

Understand Key Linux Functionalities

You'll fully understand important key functionalities of Linux through visual explanations.

How to learn Linux with this course?

Below is a guide on how to use this course effectively. You can read this part later when you start to learn relevant topics.

Command Line

In this course, we use different command line designs. When you practice, especially with remote operations, it is important to understand which command line we are talking about. Here are the different types of command line designs we are using in this course.

AWS Lightsail browser-based SSH client

These are covered in Chapter 2-6.

Normal user mode

Terminal on Mac or Powershell on Windows or VS Code for both cases

These are covered used in Chapter 7 and 8.

Local operation (not connected to the remote server)

Remote operation (connected to the remote server) – normal user mode

Remote operation (connected to the remote server) – superuser mode

Sample Files

We prepared some sample files for Chapter 2, Chapter 5, Chapter 7, and Chapter 8. If you want to download the sample files for your reference, clone the repository below.

Sample Files

Before cloning the repository, prepare the Linux Ubuntu OS environment as explained in Setting Up Linux Environment on AWS .

Once you set up the Linux Ubuntu OS environment, clone the repository.

Command Line - INPUT (for HTTPS)

git clone https://github.com/bloovee/linux-introduction.git

Command Line - INPUT (for SSH)

git clone git@github.com:bloovee/linux-introduction.git

The Chapter 5 and Chapter 8 sample files contain shell scripts with absolute paths. After you clone this repository, move all directories to your home directory (ubuntu) so that shell scripts work properly with proper absolute paths.
