Execute a command with a timeout

  <td>
    <div class="text codecolorer">
      &nbsp;timelimit -t100 somecommand

If you are looking for a command to see the disk usage by each of the rpm‘s then you can use this command:

And if you use this command very regularly then you can create an alias like

  <td>
    <div class="text codecolorer">
      &nbsp;alias rpm_size='rpm -q --queryformat "%10{SIZE}\t%{NAME}\n" '
    </div>
  </td>
</tr>
