What flag is used in DPKG to list information about a package?

The flag used in DPKG to list information about a package is the '-l' option. When you use this flag with the DPKG command, it allows you to display a list of packages that are currently installed on the system. This includes information such as the package name, version, and description, giving you an overview of what is available on the system.

Using the '-l' flag is particularly helpful when you want to quickly check the status of installed software packages, troubleshoot issues, or determine if a specific package is present. It is a common practice for system administrators when managing packages.

Other options, such as '-s', '-i', and '-v', do not serve this purpose. Specifically, the '-s' flag is used to display the status of a specified package, the '-i' flag provides detailed information about a package, and the '-v' option usually signifies verbose output, which is not directly related to simply listing packages. This precise functionality of the '-l' flag highlights its significance in package management with DPKG.
