What is Linux is too dgos
Linux is an open-source operating system that powers most of the internet servers, smartphones (Android), and increasingly, desktop computers. Unlike Windows or macOS, Linux is free and comes in many "distributions" (versions) tailored for different uses.
For developers, Linux represents power, flexibility, and control.
Servers Run Linux: Over 90% of web servers, cloud infrastructure, and supercomputers run Linux. If you deploy applications, you are likely deploying to Linux servers.
Development Environment: Many development tools work best on Linux. Docker, Kubernetes, and most DevOps tools are Linux-first.
Learning: Understanding Linux teaches you how operating systems work at a fundamental level.
Ubuntu: Beginner-friendly, most popular for desktops and servers. Great starting point.
Debian: Stable, reliable, used for servers requiring long-term support.
Fedora: Cutting-edge features, good for developers wanting latest technology.
CentOS/Rocky Linux: Enterprise-focused, common in corporate environments.
Linux power comes from the terminal - the command line interface. Instead of clicking icons, you type commands:
No related topics found.
ls # List files
cd projects # Change directory
mkdir app # Create folder
rm file.txt # Delete file
At first, this feels harder than clicking. With practice, it becomes faster and more powerful.
DevOps Careers: Required knowledge for DevOps, cloud engineering, and infrastructure roles.
Server Management: Deploy and maintain applications on Linux servers.
Automation: Write scripts to automate repetitive tasks.
Problem-Solving: Debug production issues directly on servers.
AWS/Azure/Google Cloud: Virtual machines run Linux. You SSH into them and manage via command line.
Docker Containers: Most containers are based on lightweight Linux distributions.
CI/CD Pipelines: Build and test environments typically run Linux.
You do not need to replace your OS. Options:
Start with Ubuntu - it is the most beginner-friendly distribution.
Linux is free, stable, secure, and customizable. These qualities make it perfect for servers. Since most applications ultimately run on Linux servers, understanding Linux is a fundamental skill for backend developers, DevOps engineers, and anyone working with infrastructure.
You might develop on Mac or Windows, but you deploy to Linux.
