Introduction
This introductory chapter sets the stage for the video by explaining the need for operating systems and their fundamental role in computer systems. It highlights the importance of understanding how operating systems interact with hardware and software to enable applications to function.
Introduction to operating systems
This chapter provides a detailed explanation of operating systems, emphasizing their role as intermediaries between hardware and software. It discusses the key tasks performed by operating systems, including process management, memory management, storage management, device management, security, and networking.
Introduction to virtualization and virtual machines
This chapter introduces the concept of virtualization and virtual machines. It explains how virtualization allows running multiple operating systems on a single physical machine, enhancing resource utilization and flexibility. The chapter also discusses the benefits of using virtual machines, such as testing software in isolated environments and running different operating systems simultaneously.
Setup Linux virtual machine
This chapter provides a step-by-step guide on setting up a Linux virtual machine using VirtualBox. It covers the process of downloading and installing VirtualBox, creating a new virtual machine, selecting the Linux distribution, and configuring the virtual machine settings.
Linux File System
This chapter delves into the Linux file system, explaining its hierarchical structure and the concept of a single root directory. It discusses the key directories within the Linux file system, including /bin, /sbin, /usr, /home, /var, /tmp, /dev, and /etc, and their respective purposes.
GUI Vs Command Line Interface
This chapter compares and contrasts the graphical user interface (GUI) and the command-line interface (CLI) in Linux. It highlights the advantages and disadvantages of each approach, emphasizing the importance of CLI proficiency for server administration and automation.
Basic Linux Commands
This chapter introduces a set of essential Linux commands, including pwd, ls, cd, mkdir, touch, rm, mv, cp, sudo, and history. It provides explanations and examples of how to use these commands for basic file and directory management tasks.
How to install software in Linux - Package manager (all methods)
This chapter explains how to install software in Linux using package managers. It focuses on the apt package manager used in Ubuntu and Debian-based distributions, demonstrating how to search for, install, update, and remove software packages.
How to work with Vi and Vim text editors
This chapter provides a comprehensive guide to using the vi and vim text editors in Linux. It covers the basics of navigating, editing, and saving files, as well as essential commands for efficient text editing.
Linux User Accounts
This chapter explores user accounts in Linux, explaining the different types of accounts, including superuser (root), regular users, and service accounts. It discusses the importance of user account management for security and resource control.
File Ownership and Permissions (Symbolic mode and set permission and Numeric mode)
This chapter delves into file ownership and permissions in Linux. It explains the concepts of owner, group, and others, and how to use symbolic and numeric modes to set permissions for files and directories.
Basic Linux Commands - Pipes and Redirects
This chapter introduces two powerful Linux commands: pipes (|) and redirects (>, >>). It explains how pipes connect the output of one command to the input of another, while redirects allow controlling the output of commands.
What's next? Shell Scripting and Ansible?
This concluding chapter outlines the next steps in learning Linux, suggesting that viewers explore shell scripting and Ansible for automating tasks and managing infrastructure. It emphasizes the importance of continuous learning and practice to master Linux skills.
