Explanation

rpm -qa queries all installed RPM packages. When combined with a package name like rpm -qa perl, it returns the installed version of Perl if it is present, or no output if it is not - this verifies whether the prerequisite is met. rpm -Uf upgrades or installs a package from a file, not a query. rpm -iv installs a package verbosely; it does not check if it is already installed. rpm -eh is not a valid rpm option combination.
