How do I find what dependencies a rpm file has?

RPM is a Package Manager for popular distribution such as Red Hat, Suse and many others. It is a powerful command line package management system for installing uninstalling, verifying, querying, and updating Linux computer software packages.
You can finding out what dependencies a rpm file has i.e. it will tell you what you need to install package with following command:
rpm -qpR {.rpm-file}
rpm -qR {package-name}

Otherwise you can try to install it end will get error message if some of the deps wouldnot be installed.
rpm -ivh {.rpm-file}
