The command "rpm --query --changelog ${package_name}" is used to display the changelog of a specific package in RPM-based Linux distributions.

Here's a breakdown of the command:

• "rpm" is the command for managing RPM packages.
• "--query" is an option that tells RPM to query the package database.
• "--changelog" is another option that specifies that we want to display the changelog of the package.
• "${package_name}" is a placeholder for the actual name of the package you want to view the changelog for. You need to replace it with the name of the package you are interested in.

For example, if you want to view the changelog of the package "httpd", you would run the command: "rpm --query --changelog httpd". This will display the changelog entries for the "httpd" package, providing information about the changes, updates, and bug fixes made to the package over time.
