Learn Unix with online courses and programs

Whether you want to discover more about server operating systems, scientific computing, and system administration or upgrade your skills in programming, courses in Unix can help build the skills you need for many different careers.

What is Unix?

Unix is a group of computer operating systems that Bell Labs produced in 1969 for AT&T. It is a versatile system with multi-tasking capabilities, where one user can perform multiple tasks simultaneously, and multi-user capabilities, where many users can share the same resource. It influenced many other operating systems, such as macOS and Linux.1

Unix programs work with a standardized text interface, with specific requirements, like single-purpose and interoperability in heterogeneous environments. They have a core kernel that takes care of the system and processes. Kernel subsystems can include the management of different networks, files, and processes.

The creators of Unix built it using a high-level language, which makes it easy to read, write, and understand. It also has portability and is easily movable from one system to the other. Unix follows the hierarchical directory structure (file system). This file system is known for its simplicity in terms of information storage, management, organization, and retrieval.2

How does Unix work?

The interface of Unix is similar to that of Microsoft Windows, which some users find easy to operate. The Unix operating system consists of three layers: the kernel, the shell, and the programs.

  • The kernel is the core of Unix. It distributes time and memory to programs.
  • The shell is the interface between the kernel and the user. It’s an interface that interprets the user’s commands and carries them out.
  • The commands that users input are the programs the shell passes to the kernel for execution.

Unix is a part of many applications and systems, such as Android and iOS. It has many tools and features that help developers design software and applications effortlessly.

    What are Unix and Linux?

    Linux is a Unix-like operating system. They are similar but not the same. There are two key differences between them. Most iterations of Unix are closed-source and require a license, while most Linux distributions are open-source and don’t require a license. There are a few different versions of the Unix operating system, but hundreds of different Linux distributions.

    How long does it take to learn Unix?

    It can take some time and effort to become a Unix programmer, but with the right instruction and commitment, you can become proficient. Coding can be difficult if you are a beginner, but give yourself time. Overall, the length of time it takes to learn Unix or any other programmatic skill will depend on your prior experience, education, and resources available.

    Is Unix easy to learn?

    Unix can be difficult to learn, especially for those new to command-line interfaces. However, with resources and motivation, anyone can learn Unix.
