title: cp exits with a 64 error status
body: <p>I am using a preflight bash script in <strong>packagemaker</strong> :</p>
  
  <p><code>run cp -pf "/folder/to/my/db" "/Library/Application Support/app/db</code></p>
  
  <p>The run function (that I found on StackOverflow by the way) :</p>
  
  <p><code>run() { $*; code=$?; [ $code -ne 0 ] &amp;&amp; echo "command [$*] failed with error code $code\nERROR: $@\n"; }</code></p>
  
  <p>The command <code>cp</code> returns a 64 code. What is this 64 status please?
  How can I resolve that?</p>
