title: Create ActiveRecord migration then edit in one step?
body: <p>I find myself doing this a lot:</p>
  
  <pre><code>script/generate migration my_new_migration
  </code></pre>
  
  <p>.. then select &amp; copy the generated filename, then paste it into vi to actually write the migration. </p>
  
  <p>Is there any way to do this in one step?  i.e. when the script/generate migration runs, it creates the file the automatically opens that file in an editor?</p>
  
  <p>(I'm working in an SSH terminal window on linux..)</p>
