title: Ubuntu equivalent of Yum's WhatProvides, to find which package provides a file
body: <p>Fedora's <code>yum</code> package management tool has a nice option called <code>whatprovides</code>, which lets you find what package has installed a specific binary or file. What is the equivalent command on Ubuntu?</p>
  
  <p>For example, say I'd like to find what package provided <code>/usr/bin/mysqladmin</code>. I know it should be something like <code>mysql-server*</code>. I've read that <code>apt-cache search blah</code> is a similar command, but running <code>apt-cache search /usr/bin/mysqladmin</code> returns nothing. Is there a better command?</p>
