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 by resolving dependencies and fetching them from configured repositories. Yum simplifies system administration by providing a user-friendly interface to handle software packages and their dependencies efficiently.
Developers should learn Yum when working with RPM-based Linux systems, as it is essential for managing software installations, updates, and system maintenance in enterprise and server environments. It is particularly useful for DevOps engineers and system administrators who need to automate deployments, ensure consistency across servers, and handle package dependencies without manual intervention. Use cases include setting up development environments, deploying applications, and performing system updates in production servers.
