Commands and packages relationship

Question

I want to find out what commands installing a package makes available in my console.

For example: If I want to run the command quiz in bash, I have to install a set of packages by asking apt-get to install bsdgames.

Answer 1

You can either do:

apt-file update
apt-file search quiz

or directly go to http://packages.ubuntu.com/ and use the feature "Search the contents of packages".

Answer 2

Open a terminal and run

sudo apt-add-repository universe
sudo apt-get update
sudo apt-get install bsdgames

to add the Universe repository, to update the package information and to install bsdgames, quiz is part of this package.

After that you can run

quiz

in your terminal.

Why? That's why.
