title: (Android recovery) how to let /cache/recovery/command execute more orders?
body: <p>I want to install zip from sdcard by recovery  and I write a file named command :</p>
  
  <pre><code>--update_package=/sdcard/my-rom.zip
  </code></pre>
  
  <p>put the file into <code>/cache/recovery</code>  then  run </p>
  
  <pre><code>*adb reboot recovery*
  </code></pre>
  
  <p>It works.</p>
  
  <p>but if not  wipe_data ,there are problems about android system sometimes.
  so I write the code into command file.</p>
  
  <pre><code>--wipe_data
  
  --update_package=/sdcard/my-rom.zip
  </code></pre>
  
  <p>it is not working only run the last command ,not wipe_data.</p>
  
  <p>How can I let the command execute by order?</p>
