In the world of Linux operating systems, **updating programs** has become much simpler and more convenient compared to Windows or macOS. One of the **key advantages** of this process is that you don't need to **uninstall and reinstall** a program to get the updated version. Instead, using **package management systems**, users can easily update programs with minimal effort.


In Linux systems, programs are typically distributed through **repositories**, centralized collections of software packages. When a new version of a program becomes available, developers update the **package** in the repository. As a result, users can update programs with just a few simple commands.

The `sudo apt update` command is used to **refresh** the list of available packages. After that, you can use the `sudo apt upgrade <package_name>` command to **update a specific program**. This process allows users to **quickly and efficiently** receive program updates, ensuring the **security and stability** of the system.

`<package_name>`: This is a command-line argument that specifies the name or part of the name of the program you want to update.

Compared to Windows or macOS, where updating programs often requires **large downloads** and **system restarts**, the update process in Linux is much **less intrusive** and **more efficient**. As a result, Linux users can enjoy **up-to-date versions** of programs without spending a lot of time and effort on it.

If you don't know the name of the required package, you can use the command `dpkg -l | grep <pattern>` to find the package among those already installed.

Learning Linux is valuable for many IT professions. For system administrators, DevOps engineers, and backend developers, it enables efficient server management, automation of software development and deployment, and the development and management of server-side applications. For network administrators, cybersecurity professionals, and data analysts, Linux knowledge helps effectively manage networks, ensure security, and analyze data.

In this section, we'll learn about what Linux is, and also download one of the operating systems based on it.

In this section, we will create a virtual machine on your computer and install Linux on it.

In this section, you will learn the basic skills for working with the Linux operating system, which differ from working with Windows or macOS.

In this section, you will learn how to work with users and their groups, as well as how to configure access rights for them.
