To determine whether the required packages are installed, enter commands similar to the following:

# rpm -q package_name

Alternatively, if you require specific system architecture information, then enter the following command:

# rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE} (%{ARCH})\n" | grep package_name

是不是很详细？
