How to Learn Linux: A Guide for Beginners

Are you interested in learning Linux but don’t know where to start? Linux is a powerful and popular operating system that is widely used in both personal and professional settings. This guide will give you an overview of how to get started with Linux, including tips for learning both Debian and RHEL-based variants of Linux.

Understanding Linux

Linux is an open-source operating system that is widely used in server and desktop environments. It was first released in 1991 by Linus Torvalds, and has since become one of the most popular operating systems in the world. Linux is known for its stability, security, and flexibility, and is used by many companies, including Amazon, Google, and IBM.

Benefits of Learning Linux

There are many benefits to learning Linux, especially for professionals. Here are some reasons why you should consider learning Linux:

  • It’s in high demand: Linux is widely used in enterprise environments, and there is a high demand for professionals with Linux skills.
  • It’s cost-effective: Linux is open-source, which means it is free to use and distribute.
  • It’s customizable: Linux is highly customizable, which allows for greater flexibility in configuration and deployment.
  • It’s stable and secure: Linux is known for its stability and security, which makes it a popular choice for mission-critical applications.

Getting Started with Linux

To get started with Linux, you’ll need to install a Linux distribution on your computer. There are many different distributions of Linux available, but some of the most popular include:

Each distribution has its own strengths and weaknesses, and the choice of distribution will depend on your specific needs and preferences. For beginners, we recommend starting with Debian or Ubuntu, as they are widely used and have a large community of users who can provide support.

Learning Linux Commands

One of the first things you’ll want to learn when getting started with Linux is how to use basic Linux commands. These commands are the foundation for many tasks in the Linux environment, and you’ll likely use them frequently as you work with the operating system.

Here are some of the most common Linux commands and what they do:

  • ls: Lists the contents of a directory. For example, if you type ls in the terminal, you’ll see a list of all the files and directories in the current directory.
  • cd: Changes the current directory. For example, if you want to change to the Documents directory, you would type cd Documents.
  • mkdir: Creates a new directory. For example, if you want to create a new directory called test, you would type mkdir test.
  • rm: Removes a file or directory. For example, if you want to remove a file called file.txt, you would type rm file.txt. If you want to remove a directory and all of its contents, you would use the -r flag, like this: rm -r directory/.
  • ps: Displays information about running processes. For example, if you want to see a list of all the processes running on your system, you would type ps.
  • ifconfig: Displays network configuration information. For example, if you want to see the IP address of your network interface, you would type ifconfig.

These are just a few of the many Linux commands you can use. To learn more, you can consult online resources, such as the Linux man pages or other Linux documentation. Additionally, many Linux distributions come with a built-in help system, which you can access by typing man <command> to get more information about a specific command.

Learning Debian-Based Linux

Debian is a popular distribution of Linux that is known for its stability, security, and large community of users. If you’re new to Linux, we recommend starting with Debian or Ubuntu, as they are both based on Debian and have a similar structure and package management system.
