As we know, package managers are one of the most contributors to the Linux system.
Most of us prefer the command line interface for package management such as the YUM command, DNF command, APT command, Apt-Get command, PACMAN command, and ZYPPER command based on Linux distributions.
Package Manager allows us to perform actions such as installing new software packages, removing unused software packages, updating the existing software packages, searching for specific software packages, and updating the system to latest available version, etc.
As a system administrator you should keep track of the packages installed on the system, which can save you a lot of time when setting up a new server or migrating them.
Since we already have the list, this list will help you to quickly install the required packages.
Many tools are used to manage packages on Linux, from the graphics or text-based interface to the lower-level tools used to install packages.
This is a very short and powerful exercise for newbie to manage package management.
In this tutorial we will include all major Linux distributions such as RHEL (RedHat), CentOS, Fedora, Debian, Ubuntu, openSUSE and Arch Linux systems.
1) How to List All Packages Installed on RPM Based Systems Using the RPM Command
You can use the RPM command with the -qa option to get a list of packages installed on RHEL (RedHat), CentOS, Fedora, and openSUSE systems.
RPM stands for RPM Package Manager formerly known as Red Hat Package Manager is a powerful package management system for Red Hat Enterprise Linux (RHEL) as well as other Linux distribution such as Fedora, CentOS, and openSUSE. RPM maintains a database of installed packages and their files, so you can invoke powerful queries and verification’s on your system.

8) How to Calculate the List of Packages Installed on Your System
Run the following command to calculate the list of packages installed on your Linux system. Use the package manager command according to your distribution.
$ rpm -qa --last | wc -l or $ yum list installed | wc -l or $ dnf list installed | wc -l or $ zypper se --installed-only | wc -l or $ pacman -Q | wc -l or $ dpkg -l | wc -l or $ apt list --installed | wc -l 2466
