Dnf Cheatsheet

DNF (Dandified YUM) is the package manager for RHEL, Fedora, and related Linux distributions. It handles installation, updates, and removal of software packages while managing dependencies. Most DNF commands require root privileges, typically using sudo.

DNF provides powerful options for removing packages from your system, including handling dependencies, orphaned packages, and cleaning up cached data. These commands require superuser privileges.

DNF provides various options to update your system packages. You can update all packages at once, target specific packages, apply security updates only, or schedule automatic updates for system maintenance.

DNF repositories are sources for packages. Managing repositories allows you to control which software sources are available for installation and updates. This section covers how to add, enable, disable, and configure repositories.

DNF provides powerful commands to query package information, search for packages, inspect dependencies, and verify system integrity. These tools help administrators identify what's installed, find packages to install, and troubleshoot package-related issues.

System maintenance with DNF involves keeping your system clean, efficient, and reliable. These commands help you manage package cache, verify system integrity, fix dependency issues, and perform system upgrades safely.

DNF maintains a history of all transactions (installations, removals, and updates) allowing you to view past actions, roll back changes, and analyze problems that might have occurred during package operations.

Advanced DNF operations enable system administrators to customize package management behavior, work with modular content, handle complex package relationships, and automate routine tasks for enterprise environments.
