How to start a career with Linux? Be prepared!

Key takeaways

• Learn the command line, permissions, users, networking and package management before chasing certificates.
• Practise on a real installation, because RHCSA is a hands-on exam, not a theory test.
• Choose one path after the basics: system admin, cloud, DevOps or security.

What is Linux?

Linux is an open-source operating system (OS) based on Unix. It is a powerful, versatile, and secure platform that is widely used across different types of devices, including servers, desktops, smartphones, and embedded systems. Here’s a breakdown of what Linux is:

1. Open Source:

• Open Source Software: Linux is open-source, meaning its source code is freely available to anyone. Developers can modify, distribute, and enhance the code, leading to a wide variety of Linux distributions (or "distros").
• Community-Driven Development: Linux is maintained and improved by a global community of developers, contributing to its stability, security, and performance.

2. Operating System:

• Kernel-Based: At the core of Linux is the Linux kernel, which is responsible for managing hardware resources, such as the CPU, memory, and peripheral devices, and providing a base for higher-level software.
• Multitasking and Multiuser: Linux supports multitasking (running multiple applications simultaneously) and multiuser environments, making it suitable for both individual and enterprise-level use.

3. Versatility and Usage:

• Servers and Supercomputers: Linux is the dominant OS on servers and supercomputers due to its stability, security, and performance.
• Desktop and Mobile: There are also Linux distributions tailored for desktop use (e.g., Ubuntu, Fedora) and mobile devices (e.g., Android is based on the Linux kernel).
• Embedded Systems: Linux is often used in embedded systems, such as routers, smart TVs, and automotive systems, due to its flexibility and small footprint.

4. Distributions (Distros):

• Variety of Distros: There are many Linux distributions, each designed for different purposes. Popular ones include Ubuntu, Debian, Fedora, Rocky Linux, AlmaLinux and Red Hat Enterprise Linux (RHEL); CentOS Linux is end of life, though CentOS Stream continues.
• Customization: Users can choose a distribution based on their needs, whether for general desktop use, server management, or specialized tasks like security testing (e.g., Kali Linux).

5. Security:

• Built-in Security Features: Linux is known for its security features, including strict user permissions, file encryption, and a built-in firewall.
• Regular Updates: The Linux community regularly updates the OS with security patches and improvements, making it a secure choice for many applications.

6. Command Line Interface (CLI):

• Powerful CLI: While Linux has graphical user interfaces (GUIs), it is also known for its powerful command line interface, which lets users run many tasks efficiently.
• Scripting and Automation: The CLI in Linux supports scripting, which enables users to automate repetitive tasks, enhancing productivity and system management.

7. Compatibility and Software:

• Wide Range of Software: Linux supports a vast array of software, including open-source applications and tools for development, networking, security, and more.
• Cross-Platform Compatibility: Linux can run on various hardware platforms, from personal computers to mainframes, making it highly adaptable.
