rpm:tldr:15426

This command is using the RPM package manager to upgrade or reinstall a specific package that is specified by the variable ${package_name}.

Here's a breakdown of the command:

• rpm: This is the command that invokes the RPM package manager.
• --upgrade: This option tells RPM to upgrade the package if it is already installed, or install it if it is not present on the system.
• ${package_name-rpm}: This is a variable that should be replaced with the actual name of the package you want to upgrade or reinstall. The -rpm suffix indicates that it is an RPM package, but you should remove it and replace it with the actual package name.
• --force: This option instructs RPM to override any dependency checks or installation conflicts and forcefully upgrade or reinstall the package. It is useful in situations where you want to ensure that the package gets installed or upgraded regardless of the current system state.

Overall, this command is used to forcefully upgrade or reinstall a specific package using the RPM package manager.
