What RPM command is used to display detailed information about a package?

The command option that displays detailed information about a package in RPM is the one that includes the '-qi' flag. When you use rpm -qi package_name, it shows the package name, version, release, architecture, and other information such as the package's summary, description, and installation date. This makes it useful for obtaining comprehensive details about a specific RPM package that is installed on the system.

The other command options serve different purposes:

• The '-qd' flag would be used to display the documentation files that come with the package.
• The '-ql' flag lists all the files that were installed with the package.
• The '-qf' option is used to find out which package a specific file belongs to.

Each command provides a different facet of information related to RPM packages, but for detailed package information, '-qi' is the correct choice.
