      Spooling</a></h1>

      <p>The <tt class="COMMAND">lpr -r</tt> option is extremely
      dangerous and has proven to be fatal to a large number of
      system administrators, so it should be used with caution.
      Unfortunately, it is used in a large number of shell scripts
      and by default in a vast number of programs so it is present
      in the <b class="APPLICATION">LPRng</b> software.</p>

      <p>Its action is quite simple. After sending the print job to
      the spooler, it will try to unlink the original files. It
      will do the unlinking operation as the original user, but if
      the original user had permissions to remove, say, <tt class=
      "FILENAME">/etc/password</tt>, then the file will be
      removed.</p>
