DNF
DNF (Dandified YUM) is a package manager for RPM-based Linux distributions, such as Fedora, RHEL, and CentOS, that handles software installation, updates, and dependency resolution. It is the successor to YUM (Yellowdog Updater, Modified), offering improved performance, better dependency solving with libsolv, and a cleaner API for automation and scripting.
Developers should learn DNF when working on or deploying applications for RPM-based Linux systems, as it is the standard tool for managing software packages in modern distributions like Fedora and RHEL 8+. It is essential for tasks such as installing development libraries, updating system dependencies, and automating deployments in server environments, ensuring efficient and reliable package management.
