How do you get a list of files that have been installed from a dpkg package?

`dpkg -I` is not a standard or recognized option for listing files within a package; `-i` is typically used for installing a package.

The `dpkg -C` command is used to check for broken or partially installed packages, not to list the files within a package.

The `dpkg -s pkgname` command displays the status information (e.g., installed, removed) about a package, but it does not list its files.

The `dpkg -S filename` command searches for which installed package owns a particular file, which is the opposite of listing files within a known package.

The `dpkg -L pkgname` command is specifically designed to list all the files and directories that are installed as part of the specified Debian package. This allows users to see the entire file structure provided by a package.
