Linux Essentials 2.0: Why You Should Learn the Basics of Linux
When people talk about Linux, they often associate it with programmers, system administrators, and highly technical professionals. But its presence in the professional world now extends to many other areas. Linux is present in numerous technological environments that are part of our daily lives, and acquiring a basic understanding of it can make a real difference in terms of employability and professional performance—both for those with a technical background and for those who work with technology in other roles.
Who might find Linux knowledge particularly useful?
- Software development professionals, given Linux’s presence in numerous work and deployment environments.
- Technical support or help desk professionals, who may encounter Linux systems in infrastructures requiring maintenance and support.
- People interested in cybersecurity, a field in which Linux is present in many of the tools, systems, and learning and work environments.
- Those who manage technology projects in coordination or management roles, because basic training facilitates an understanding of concepts, improves communication with technical teams, and helps them make more informed decisions.
The importance of Linux is also evident when examining organizations’ technology infrastructure. A report titled “The State of Global Open Source 2025,” compiled by Linux Foundation Research based on 851 responses from professionals worldwide, estimated that free and open-source software accounts for 55% of operating systems in current use and 49% of cloud and container technologies. The study itself attributes the first of these figures to the maturity achieved by the Linux distribution ecosystem.
A Skill That Gives You Independence
One of the reasons why knowing the basics of Linux is valuable is the independence it provides. Many technical problems that usually end in a reboot or a call to the support team can be addressed differently when you have even a basic understanding of how the system works.
Knowing how to read an error message, understanding the impacts of your desktop activities on the underlying system, or overcoming your fear of the command line changes the way you interact with technology and your feelings of autonomy.
This is particularly relevant because more and more professions rely on digital tools, including many jobs that are far removed from strictly technical roles. Today, technological literacy encompasses a broader scope than simply using a spreadsheet or email, and knowing the fundamentals of the systems behind these tools helps users better understand how they work, interpret certain issues, and communicate more effectively with specialized teams.
At my training firm, Femxa, we often see that this first encounter with Linux acts as a sort of trigger. Once someone understands the basic logic of this operating system, they begin to view much of the technology they use daily in a new light, and concepts related to files, permissions, processes, or commands start to make sense. In many cases, this initial understanding also sparks an interest in continuing to learn, whether through self-study or more structured training.
Linux Professional Institute has also recognized the central role of Linux in modern technology, and the value of having some Linux skills even if you are not a technology expert. With these ideas in mind, LPI created the Linux Essentials certificate, which has just enjoyed a major update and has been released as version 2.0.
An Investment of Time with a Generous Return
The basics of Linux can be learned gradually using easily accessible resources. Most distributions are free and can be tested in virtual machines, allowing users to experiment with the system, familiarize themselves with its essential concepts, and gain proficiency as they put them into practice.
This learning enhances an overall understanding of how technology works and provides a solid starting point for those who wish to specialize later in areas such as systems, networking, cybersecurity, or development. For someone just starting to code, for example, becoming familiar with the terminal, understanding file structures, and learning how permissions work provides context for much of the knowledge they’ll encounter later on.
Therein lies much of the value of knowing the fundamentals of Linux. Approaching that “black screen” and gradually understanding its logic allows you to gain autonomy, navigate technological environments with greater confidence, and open up new possibilities for learning and specialization.
This approach to learning also aligns with Femxa´s philosophy, where technology is an integral part of both what we teach and our own way of working. We provide people with training in technological skills, collaborate with specialized partners, and apply innovation and digital transformation to our own processes.
This dual perspective allows us to gain a deep understanding of which skills are gaining importance and how to translate them into training that is useful for both individuals and the job market. Currently, much of this training comes back to Linux and the open source tools that run on it.
