How to Learn Linux

As the most popular open source operating system, Linux is quickly becoming an essential part of today’s digital landscape. Learn about the skills you need to join the Linux space.

How to Learn LinuxThere’s no doubt that Linux is quickly becoming a powerful force in the IT industry. In fact, you’re probably using Linux without even knowing it! From smartphones and home media centers to smart thermostats and in-car GPS systems, this open-source operating system is quietly running nearly all supercomputers and cloud servers that power our daily lives.

With such a significant impact on the computing industry, it’s easy to understand why Linux has become a core skill for IT professionals.

Why Is Linux So Prevalent?

There are multiple reasons why Linux is considered one of the most diverse and powerful operating systems in the world. To understand why Linux is loved by many, it is important to identify its defining characteristics.

  • Open Source: As Denise Dumas, the vice president of software engineering and operating systems at Red Hat, said in a recent CompTIA webinar about Linux, “Open source is a place where innovation ferments and happens.” When software is released under an open source license, people can view and build upon the software’s original source code. This feature encourages software developers to adopt Linux and apply their own improvements to the code. As result, Linux’s public domain drives constant evolution and advancement.
  • UNIX-like System: Linux behaves in a similar manner to a Unix system. This means that the operating system relies on multiple parts/programs that carry out specific jobs collectively. This is a fundamental principle of good system design and is at the core of what makes Linux so great.
  • Stable: As a public domain that is constantly evolving, Linux remains an incredibly secure operating system. In the words of Eric S. Raymond, “Given enough eyeballs, all bugs are shallow.” Linux’s general public license allows a plethora of software developers to rapidly identify issues in code and just as quickly respond to fix the errors.
  • Free: Linux is priceless. Literally! The underlying software of Linux has been free to download and install since its creation. For this reason, Linux remains one of the most accessible, diverse operating systems to this day.

Essential Linux Skills

But what skills do you need to understand how to navigate around a Linux system? Starting first with a desire to learn, you can begin improving upon the following skills:

  • Service configuration: The ability to plan, establish, and maintain a consistent system life cycle to ensure a healthy system
  • Scripting/development: The ability to write code using command languages and programming languages, such as Bash or Python
  • Security: The ability to protect a Linux system from malicious hackers
  • Troubleshooting: The ability to leverage different Linux commands to identify and fix bugs
  • Professional skills: The ability to problem solve, communicate, work in teams, etc.

How to Learn Linux

It’s never been a better time to begin exploring Linux. Over the years, companies such as Red Hat have put effort toward making system administration and development easier to master. In turn, today’s Linux graphical user interfaces (GUIs) are highly functional and significantly less intimidating.

To begin your journey through the Linux space, you will have to make a few choices:

  1. Choose a Linux distribution: Linux is not developed by a single entity, so there are multiple different distributions (distros) that can take code from Linux open-source projects and compile it for you. Since these distros choose your default software (desktop environment, browser, etc.), all that’s left for you to do is boot up and install.
  2. Choose a virtualization solution: Linux virtualization is used to isolate your operating systems so you can run multiple virtual machines on one physical machine, and in turn save time, money and energy on maintaining multiple physical servers. Some popular selections include VMWare, VirtualBox (Oracle) and Hyper-V (Microsoft).
  3. Set up your Linux play space and explore: Once you log in to your virtualization environment, you can start learning and practicing. The best way to become comfortable with Linux is to jump in and get your hands dirty.

Ready to take your Linux experience to the next level? Learn from the experience of others and consider getting an IT certification like CompTIA Linux+.

  • Find a mentor: Though the Linux community is incredibly diverse, there is one thing that all Linux users have in common: They LOVE Linux. Develop a relationship with an experienced Linux user to not only gain valuable insight on Linux topics, but also discover the source of their passion!
  • Join a Linux study group: Speaking of community, it’s important to realize that you’re not alone as a Linux beginner! As the open-source operating system gains popularity, multiple IT pros are converting to Linux daily. Seek out forums, study groups and other learning opportunities to develop your skills alongside others.
  • Get certified: There’s no better way to boost your confidence and prove your understanding of Linux than becoming CompTIA Linux+ certified. Preparing for CompTIA’s Linux+ certification exam will help you fill gaps of knowledge and validate your Linux skills.
