Find Packge for Linux Command

I want to find the package which installed the command xfce4-display-settings.

To find out, where the command is located, I can use the which command.

$ which xfce4-display-settings
/usr/bin/xfce4-display-settings

Now, I want to know which package installed the command.

• Fedora:

  $ dnf repoquery -f /usr/bin/xfce4-display-settings
  xfce-settings-0:4.12.0-6.fc23.x86_64
  

  (Source, search for “Display package name that owns the given file”)

• Debian/Ubuntu:

  dpkg --search /usr/bin/xfce4-display-settings
  

  (Source, Section 8.5)

Now, I can search for the package and find the website of the package. There is also the source code available in a repository.
