Which command is used to list all currently installed packages using RPM management?

The command used to list all currently installed packages using RPM management is "rpm --query --all." This command specifically interacts with the RPM Package Manager, which is commonly used in distributions like Red Hat, Fedora, and CentOS. The "rpm" command allows the user to query the database of installed packages, and the "--query" option specifies that the user is interested in retrieving information about those packages. Including the argument "--all" instructs the command to return a list of every package that is currently installed on the system.

Other commands listed relate to different package management systems. "dpkg --list" is used for Debian-based systems, such as Ubuntu, to list packages managed by the dpkg tool. "yum list installed" also pertains to RPM-based systems, but it's a higher-level package manager that can handle dependencies and install packages from repositories. "apt list" is specific to the Debian package manager (APT) and is not applicable to RPM management either. This highlights the importance of using the correct package management command according to the system's underlying package management technology.
