title: Android command list
body: <p>I have many questions about Android command. I do not know where I should start But, anyway, I have put all question related Android commands. Here ;</p>
  
  <ul>
  <li>Is subset of Linux commands come in Android by default ? Or, Are we installing something ?</li>
  <li>In system/bin, there are lots of commands. Where can I find their meaning ? I have tried <code>man</code>, but <code>man</code> is not built in.</li>
  <li>Can I start and stop application via <code>start</code> and <code>stop</code> command ?</li>
  <li>Why cannot I run the reboot from  terminal emulator ? The error <code>permission is denied</code>.</li>
  </ul>
