Yum
Yum (Yellowdog Updater, Modified) is a command-line package management utility for RPM-based Linux distributions, such as Red Hat Enterprise Linux, CentOS, and Fedora. It automates the process of installing, updating, removing, and managing software packages and their dependencies from repositories. Yum simplifies system administration by resolving dependencies and handling package transactions efficiently.
Developers should learn Yum when working with RPM-based Linux systems, particularly for server administration, DevOps tasks, or deploying applications on enterprise Linux environments. It is essential for maintaining system software, installing development tools, libraries, and managing dependencies in production or development setups, ensuring consistent and reproducible environments.
