write the output of a command to /var/log/user.log… each line will contain $USER, making this easy to grep for.

  <td>
    <div class="text codecolorer">
      &nbsp;log() { (echo "$ $@";$@) | logger -t $USER; }
    </div>
  </td>
</tr>

This command is useful if you want to copy the output of a series of commands to a file, for example if you want to pastebin the output from ‘uname -a’, ‘lspci -vvv’ and ‘lsmod’ for video driver trouble-shooting on your favorite Linux forum.
