Linux Journal ☛ Mastering Software Package Management with Yum and DNF on CentOS and RHEL
Software package management is an essential skill for any system administrator working with GNU/Linux distributions such as CentOS and RHEL (Red Hat Enterprise Linux). Managing software efficiently ensures that your system remains secure, up-to-date, and optimized for performance.
