Introduction

Linux is a powerful and flexible open-source operating system, widely respected for its stability, security, and adaptability. As someone just beginning this journey, I’ve started exploring the foundational aspects of Linux—especially its command-line interface and core functionalities. In this article, I’ll be sharing some key insights I’ve picked up along the way to help fellow beginners navigate Linux with confidence.

🔍 Understanding the Linux Filesystem

The Linux filesystem is organized in a hierarchical structure that starts at the root directory (/). Here are a few important directories every user should know:

/home – Contains personal files for each user.

/etc – Houses system-wide configuration files.

/bin – Stores essential binary executables needed for system operations.
