Welcome to the "100+ Essential Linux Commands" Series
The Ultimate Guide to 100+ Linux Commands for Everyday Use

Linux is a powerful and popular open-source operating system built on the Linux kernel. It’s widely used in enterprise environments to support production workloads and run critical applications.

In the early days, Linux was mostly used by power users and system admins. There was no graphical interface - just a black screen and a blinking cursor. Everything was done through the command line interface (CLI), which could feel pretty intimidating for new users.

Over time, Linux has grown massively and is used by home users, students, developers, and tech enthusiasts alike. Modern Linux distributions (also called distros) come with beautiful, user-friendly desktops that make it much easier for beginners to get started.

Some of the most popular desktop Linux distros include:

  • Ubuntu
  • Fedora
  • Debian
  • Linux Mint
  • Zorin OS
  • Elementary OS

Regardless of the numerous distributions that offer a GUI (Graphical User Interface) for user interaction, the heart of Linux administration still beats in the command line interface (CLI).

Executing commands is widely regarded as the professional way of managing a Linux system.

After all, most of the Virtual Private Servers (VPS) and cloud instances running Linux are exclusively administered via the command line interface.

As such, having a good grasp of Linux commands will set you apart from your peers and provide you with crucial skills for effective Linux system management.

Familiarity with working on the command line will also prove valuable as you scale the IT ladder and venture into other disciplines such as Cloud and Cybersecurity.
