Day 10 of 30 Days of Linux Mastery focuses on managing software packages using the dnf package manager.
dnf, standing for Dandified Yum, is the package manager used in RHEL 9 systems for installing, updating, and removing software packages. It also handles repositories and software streams.
Core dnf commands include installing, removing, updating, searching, viewing package info, listing installed packages, and cleaning cache. Auto-confirm prompts in scripts or labs using -y.
Real-world scenarios demonstrate installing, confirming, and removing packages with dnf commands. Additionally, enabling specific software versions and checking package dependencies are covered.
