title: Git GUI and gitk is not present after installing Git
body: <p>I am using <a href="https://en.wikipedia.org/wiki/Ubuntu_version_history#Ubuntu_11.10_.28Oneiric_Ocelot.29" rel="nofollow noreferrer">Ubuntu 11.10 (Oneiric Ocelot)</a> and have just installed Git using</p>
  <pre><code>sudo apt-get install
  </code></pre>
  <p>The basic Git commands seem to work.  (I have created a repository and added a directory structure to it.) But not Git GUI or gitk.  This is what I get:</p>
  <pre><code>sudo git gui
  </code></pre>
  <p>Output:</p>
  <pre><code>git: 'gui' is not a git command. See 'git --help'.
  
  
  Did you mean one of these?
  grep
  init
  pull
  push
  </code></pre>
  <p>For gitk:</p>
  <pre><code>sudo gitk
  </code></pre>
  <p>Output:</p>
  <pre><code>sudo: gitk: command not found
  </code></pre>
  <p>Do those commands run on Ubuntu and do I need to install them separately?</p>
