What Is Linux?

In some ways, Linux and other operating systems have many things in common. It also offers the same kinds of programs that you can see and use in other well-known operating systems, such as Windows and macOS. The three of them all have word processors, web browsers, simple game programs, photo and video editors, and so on. What sets Linux apart, however, is the fact that it is open-source.

Being open-source means that the code used to create Linux is available to the public. Anyone skilled enough can view, replicate, and use it to make their own programs. Because of this, Linux has become really popular and is now considered the largest open-source software in the world. Among the most popular devices that use Linux are Android phones, Chromebooks, and certain wearable gadgets.

Like any other operating system, Linux takes some time to learn and master. However, with the right amount of effort and dedication, you can acquire the skills to become an accomplished Linux system administrator.

What Does a Linux System Administrator Do?

If you enroll in a Linux system administration course in the USA, you can land a job in the IT industry as a system administrator for this operating system. It is quite a lucrative occupation, which can help you earn $60,000 and $100,000 annually, depending on the company you are working for and your current skill level.

Being a Linux system administrator is not easy, though. There are many tasks that you must accomplish, and here are a few examples:

Understanding How the Linux Operating System Works

The main prerequisite of becoming a Linux system administrator is having the ability to navigate through the operating system. At the very least, you should be able to perform and execute all the software’s most essential functions and commands. Linux uses C, so basic knowledge of this programming language is vital to becoming a good system administrator.

Additionally, it is a requirement for you to understand some fundamental concepts about the Linux operating systems. A few examples include:

  • Linux User Management
  • Basic Bash Command
  • Group Management and Administration
  • Bug Detection and Malware Prevention
  • Linux File Systems and Management

Setting Up the Hostname and Performing Other Basic Configurations

A huge part of the job of a Linux system administrator consists of performing some basic configurations using the operating system’s terminal. To do this task properly, you should set up a hostname for yourself first.

All the configurations and most of the other duties of the Linux system administrator are done using the terminal. This means that if you want to be successful in this job, you should memorize the most common commands. If you are just starting your career, it is good to create a cheat sheet where all of the useful commands are listed. Slowly, you will remember all of them without looking at your list.

Managing File Systems

In programming, a file refers to any recorded data stored in the computer, including documents, directories, and programs. A system should be created to properly index and organize these files to avoid confusion and foster work efficiency. File systems differ from one operating system to another, so Linux has its own, too.

Managing all of the file systems is among the essential tasks you will do as a Linux system administrator. In preparing for this role, it is advisable to read about the file systems and file system hierarchy in Linux. Learning the usual commands that will be used for this task is also a requirement.

If you have any previous experience as an admin for another operating system, it will help to read how Linux file systems compare with others. Some of the commands that are used in Windows and macOS probably have a counterpart in Linux.

Dealing With People Within the Organization

If you want to become an exemplary Linux system administrator, you should possess all the necessary IT knowledge needed for the job. More than that, though, you should also have some social skills because it is highly likely that you will need to interact with other people within your organization or company.

In most cases, you will work with a group of other IT professionals, so all of you should be able to work as a team. Sometimes, you will be called to check and repair a certain computer. When this happens, you will have to explain the problem to the user to prevent it from ever arising again.

The ones listed above are just a few of the primary duties of a Linux system administrator. There are other tasks that you might need to do, depending on the company you are working for.


Being a Linux system administrator is not easy, but it is a pretty rewarding profession. If you think that this is the kind of job that you want to do in the future, contact us at Yellow Tail Tech.
