Linux is a popular open-source operating system that is based on the Linux kernel. It is widely used in enterprise environments to support production workloads and host crucial enterprise applications.

Initially, Linux targeted power users and enterprise environments. Its lack of a graphical display made it quite intimidating for most users. Administration of the system was purely done on the command line interface (CLI) which entails running commands on a black console.

Over time, Linux has grown in leaps and bounds and has seen its adoption by desktop lovers and home users. Modern Linux distributions provide a desktop environment that enhances user experience and makes it easy especially easy for beginners to learn the ropes and use the system. Popular desktop Linux distributions include Ubuntu, Fedora, Debian, Zorin, and Elementary Linux.

Regardless of the numerous distributions that offer a GUI (Graphical User Interface) for user interaction, the most preferred way of running a Linux system is through the command line interface (CLI). Running commands is considered the professional way of managing a Linux system. After all, most of the VPS or cloud instances running Linux are only 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 needed to manage a Linux system. 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.

This section provides a list of essential Linux commands that will help you get started. Try our blazing fast NVMe powered VPS hosting for some practice.
