title: how to start growl via the command line
body: <p>I have a bash script that uses growlnotify to send notifications. However, growlnotify doesn't work if Growl isn't already running, and it won't auto start Growl if it needs it, either. So I want to be able to check if Growl is running, and then start it if it isn't.<br>
  I'm thinking of doing something like:</p>
  
  <pre><code>g=$(ps -e | grep Growl | grep -v grep)
  if [ -z "$g" ]  # Growl isn't running
  then
  # (start Growl)
  fi
  </code></pre>
  
  <p>How would I start Growl via the command line?</p>
