Here\’s a one-liner to get the info on all the packages installed on your system.
rpm -qa –info |tee All_rpms_Info
This is what it does, when you query the rpm database with the –info parameter, then the output looks something like the below, which is quite helpful.

Summary : The RPM package management system
The RPM Package Manager (RPM) is a powerful command line driven
package management system capable of installing, uninstalling,
verifying, querying, and updating software packages. Each software
package consists of an archive of files along with information about
the package like its version, a description, etc.
So, this is probably much more useful info. All the output is displayed on the terminal as well as written in the file called All_rpms_info. 🙂
