Displaying (dpkg and rpm) package space

Package management systems such as dpkg and rpm are used to install, remove, and manage software packages in Linux and Unix operating systems. The dpkg tool is used in Debian-based systems such as Ubuntu and the rpm tool is used in Red Hat-based systems such as CentOS. These tools not only provide an easy way to manage software packages but also offer valuable information about disk space usage by the installed packages. One important use of the dpkg and rpm tools is to display the package space, which refers to the amount of disk space used by the installed packages. By using these tools, administrators can identify the packages that are consuming the most disk space and make decisions on whether to remove or keep them. This is particularly useful in systems with limited disk space, where optimizing the use of disk space is critical to avoid system crashes, performance issues, or data loss.
