Show RPM dependent packages
Dependencies are often a problem when manipulating packages, such as installing, upgrading, or removing RPM packages.
So to avoid these problems, it is important to check the dependencies in advance.
To check what package a particular package depends on, run the rpm command with the "-q" option in combination with the "-R" option to display the name of the dependent package.
