“pacman –query” is an option for the pacman package manager in Arch Linux and its derivatives. It is used to query information about installed packages on the system.
This option allows the user to retrieve information about installed packages, including package names, versions, dependencies, and files. The user can also use this option to search for packages that match specific criteria, such as searching for all installed packages that contain a certain file or belong to a specific group.
