The Linux rpm command is used to manage packages.
rpm (full spelling in English: redhat package manager) was originally a program used by the Red Hat Linux distribution to manage various Linux packages. It is very popular because it follows the GPL rules and is powerful and convenient. Gradually adopted by other distributions. The emergence of the RPM package management method makes Linux easy to install and upgrade, which indirectly improves the applicability of Linux.
