Which command is used for package management in Red Hat systems?

In Red Hat-based systems, the command used for package management is yum, which stands for Yellowdog Updater Modified. This is a powerful package manager that simplifies the process of installing, updating, and removing software packages on systems like Red Hat Enterprise Linux and CentOS. Yum allows users to resolve package dependencies automatically by retrieving them from configured repositories, making it easier to handle software installations and updates without manually downloading each dependency.

The other options are specific to different Linux distributions: apt is used in Debian-based systems, dpkg is the low-level package manager for Debian, and zypper is used in openSUSE for package management. Each of these commands is tailored to the package management system and architecture of their respective distributions, further emphasizing why yum is the appropriate choice for Red Hat systems.
