Introduction
Linux is a foundational technology for cloud infrastructure, servers, containers, automation platforms, and modern DevOps workflows.
DevOps engineers frequently work with Linux servers to deploy applications, configure services, investigate logs, automate operational tasks, and manage cloud infrastructure.
Understanding the command line and core Linux concepts makes it easier to work with tools such as Docker, Kubernetes, Terraform, CI/CD platforms, and cloud environments.
Core Topics
Start with these core areas to build a strong Linux foundation.
Understand the Linux operating system, distributions, the command-line interface, users, directories, and the basic concepts required to work with Linux servers.
Key Topics
Learn how Linux organizes files and directories and understand important locations used by applications, users, services, and system processes.
Key Topics
Learn essential commands for navigating the file system, managing files, searching data, monitoring systems, and working efficiently from the terminal.
Key Topics
Understand Linux users, groups, ownership, read, write, and execute permissions used to secure files and system resources.
Key Topics
Learn how applications run as processes and how background services can be managed using modern Linux service management tools.
Key Topics
Use shell scripts to automate repetitive tasks, manage servers, deploy applications, process files, and build simple automation workflows.
Key Topics
Command Line
These commands form part of the everyday toolkit for working with Linux systems.
pwdDisplay the current working directory.
lsList files and directories.
cdChange the current directory.
mkdirCreate a new directory.
cpCopy files or directories.
mvMove or rename files.
rmRemove files or directories.
grepSearch for text inside files or command output.
findSearch for files and directories.
psDisplay running processes.
topMonitor running processes and system resources.
dfDisplay disk space usage.
DevOps Applications
Linux skills are used throughout modern infrastructure, development, automation, and operations workflows.
DevOps engineers use Linux to configure, maintain, troubleshoot, and automate servers and cloud virtual machines.
Linux environments are commonly used to deploy web applications, APIs, databases, and backend services.
Docker and many container-based workflows rely heavily on Linux concepts, processes, networking, and file systems.
Linux is frequently used as the operating environment for build servers, automation pipelines, testing, and deployments.
Cloud virtual machines and infrastructure platforms commonly use Linux-based operating systems.
Shell scripts and command-line tools help automate system administration, deployments, monitoring, and operational tasks.
Learning Roadmap
Follow this structured path to build practical Linux knowledge.
Become comfortable navigating directories and running basic commands from the command line.
Learn how files, directories, configuration files, logs, and application data are organized.
Practice creating, copying, moving, deleting, searching, and editing files from the terminal.
Understand users, groups, ownership, and permissions to manage secure Linux environments.
Learn how to inspect processes, manage services, check logs, and troubleshoot applications.
Automate repetitive tasks and build practical scripts for DevOps workflows.
Practical Workflow
A typical DevOps workflow may involve accessing Linux servers, checking application logs, managing services, running automation scripts, and monitoring system resources.
