The messageindicated whether the whole path was removed or whether part of the path remained for some reason. The STDERR section requires thisdiagnostic when the entire path specified by a <i>dir</i> operand is not removed, but does not allow the status message reportingsuccess to be written as a diagnostic.</p><p>The <i>rmdir</i> utility on System V also included a <b>-s</b> option that suppressed the informational message output by the<b>-p</b> option. This option has been omitted because the informational message is not specified by this volume ofIEEE Std 1003.1-2001.</p></blockquote><h4><a name="tag_04_123_19"></a>FUTURE DIRECTIONS</h4><blockquote><p>None.</p></blockquote><h4><a name="tag_04_123_20"></a>SEE ALSO</h4><blockquote><p><a href="rm.html"><i>rm</i></a> , the System Interfaces volume of IEEE Std 1003.1-2001, <a href="../functions/remove.html"><i>remove</i>()</a>, <a href="../functions/rmdir.html"><i>rmdir</i>()</a>, <a href="../functions/unlink.html"><i>unlink</i>()</a></p></blockquote><h4><a name="tag_04_123_21"></a>CHANGE HISTORY</h4><blockquote><p>First released in Issue 2.</p></blockquote><h4><a name="tag_04_123_22"></a>Issue 6</h4><blockquote><p>The normative text is reworded to avoid use of the term "must" for application requirements.</p></blockquote><div class="box"><em>End of informative text.</em></div><hr><hr size="2" noshade><center><font size="2"><!--footer start-->UNIX ® is a registered Trademark of The Open Group.<br>POSIX ® is a registered Trademark of The IEEE.<br>[ <a href="../mindex.html">Main Index</a> | <a href="../basedefs/contents.html">XBD</a> | <a href="../utilities/contents.html">XCU</a> | <a href="../functions/contents.html">XSH</a> | <a href="../xrat/contents.html">XRAT</a>]</font></center><!--footer end--><hr size="2" noshade></body></html>⌨️ 快捷键说明
