dpkg-deb:tldr:43ff9

The command dpkg-deb --info ${filename-deb} is used to display information about a Debian package (.deb file).

Here's a breakdown of the command:

• dpkg-deb: This is the command-line tool used for working with Debian (.deb) packages. It allows you to perform various operations like installing, removing, querying, or extracting information from packages.

• --info: This is an option or parameter for dpkg-deb command. It specifies that we want to display information about the package.

• ${filename-deb}: This is a placeholder for the actual filename of the Debian package (.deb) file you want to get information about. You need to replace ${filename-deb} with the actual filename and extension (e.g., package.deb).

So, when you run the command with a specific .deb file, it will provide you with information such as the package name, version, maintainer, installed size, description, dependencies, and other metadata associated with that package.
