Updating programs in Linux is simpler and more convenient than in Windows or macOS. You don't need to uninstall and reinstall anything, package managers handle updates automatically.

Software is stored in repositories, centralized collections of packages. When developers release new versions, they update the repository, allowing you to upgrade programs with just a few 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.
