title: Unlock multiple android devices through adb
body: <p>I have been successfully using <code>adb shell input keyevent 26</code> to unlock an android phone over adb.</p>
  
  <p>However, when I connect multiple devices to my mac this is reutrned:</p>
  
  <blockquote>
    <p>error: more than one device/emulator</p>
  </blockquote>
  
  <p>Is there a way to unlock multiple android devices at once through a shell script?</p>
  
  <p>Thanks,</p>
