dnf: Upgrade installed packages to the newest available versions.

$ sudo dnf upgrade

try on your machine

The command "sudo dnf upgrade" is used in Linux systems, specifically those that use the DNF package manager (such as Fedora and CentOS), to upgrade installed software packages.

Here is a breakdown of the command:

"sudo" is a command that allows users to run programs with the security privileges of another user, typically the system administrator. By using "sudo" at the beginning of the command, it confirms that the command will be executed with administrative privileges.
"dnf" stands for Dandified YUM, which is an open-source package manager used primarily in Fedora-based Linux distributions. It is used to manage the installation, removal, and upgrade of software packages.
"upgrade" is an argument of the "dnf" command, specifying that the command is intended to upgrade installed packages. When executed, DNF will check for newer versions of installed packages and upgrade them if available.

By running "sudo dnf upgrade," you initiate the upgrade process for all installed packages on your system. This command will prompt you for your password (as "sudo" grants administrative privileges), and then DNF will check for available updates from the enabled software repositories. If newer versions are found, it will prompt you to confirm the upgrades, and then proceed with the installation of the updated packages.
