Overview

The course is designed to equip software developers with essential Linux command-line skills that are crucial for daily development tasks. It emphasizes practical, real-world applications, helping developers become more efficient and confident when working in Linux environments. By mastering these tools, learners will improve their productivity and streamline their development workflow. Throughout the course, you'll dive into hands-on examples that demonstrate the power of Linux's command-line interface for tasks such as shell scripting, Docker management, and debugging. The course bridges the gap between basic knowledge and advanced proficiency, focusing on skills that are directly applicable to software development rather than system administration. What sets this course apart is its focus on developer-specific tasks and tools. It avoids unnecessary system administration details and instead highlights techniques like shell scripting and leveraging Docker to enhance your workflow. This practical approach ensures that learners can apply what they learn immediately in their development environments. This course is ideal for software developers who have a basic understanding of computers and are looking to improve their Linux command-line skills. While prior knowledge of file systems and text editing will be helpful, no deep Linux expertise is required. By the end, you'll have a solid grasp of Linux command-line tools and techniques to solve real development challenges.

Syllabus

How the Command Line Works

In this section, we explore the command-line interface (CLI) structure, distinguish between shell and command line, and apply basic command syntax for navigation and system interaction.

Working with Processes

In this section, we explore Linux processes, their attributes like PID and EUID, and tools such as ps, lsof, and signals for managing and troubleshooting running programs.

Service Management with systemd

In this section, we explore systemd service management using systemctl, analyze service status, and configure service behavior for efficient Linux system administration.

Using Shell History

In this section, we explore shell history navigation, configuration file customization, and command-line shortcuts to enhance efficiency and reduce repetitive tasks.

Introducing Files

In this section, we explore Linux file structures, types, and operations, focusing on practical commands and editing techniques for efficient development and troubleshooting.

Editing Files on the Command Line

In this section, we explore nano and vim text editing techniques, focusing on efficient patterns, workflow efficiency, and cross-tool adaptability for command-line productivity.

Users and Groups

In this section, we explore Linux user and group management, covering creation, modification, and permissions.

Ownership and Permissions

In this section, we explore Linux file permissions, ownership, and commands like chown and chmod to manage access control and system security effectively.

Managing Installed Software

In this section, we explore Linux package managers, secure software installation, updates, removal, and compiling from source.

Configuring Software

In this section, we explore Linux configuration hierarchy, command-line arguments, environment variables, and systemd integration.

Pipes and Redirection

In this section, we explore pipes, file descriptors, and I/O redirection to build efficient command-line workflows using tools like awk, sort, and uniq.

Automating Tasks with Shell Scripts

In this section, we explore Bash scripting basics, including shebangs, script execution, and testing for automation and system control.

Secure Remote Access with SSH

In this section, we explore SSH fundamentals, including public key cryptography, key-based authentication, and tunneling for secure remote access.

Version Control with Git

In this section, we explore Git setup, terminology, and advanced concepts like bisecting and rebasing.

Containerizing Applications with Docker

In this section, we explore Docker container workflows, image creation with Dockerfiles, and container vs. VM differences to enable consistent application deployment and isolation across environments.

Monitoring Application Logs

In this section, we explore Linux logging with systemd and journald, analyze system and service logs using journalctl, and configure structured logging for effective troubleshooting.

Load Balancing and HTTP

In this section, we explore HTTP troubleshooting with curl, analyze common status code pitfalls, and design effective header handling strategies for real-world web development.
